How to Protect Your PC from Being Infected

Last time we have discussed how to guard PC against viruses, today we are going to talk more details about how to change settings of Chrome to protect your PC from being infected with viruses while browsing online.

The Internet is an integral part of our lives, and many of us use it constantly throughout the day. But that connectedness has increased the risk of infection by viruses and malware, leading to potential data loss and identity theft.

Therefore, every internet user should be versed in how to protect your PC from being infected with viruses.

STEP 1: Avoid clicking on everything.

There are thousands of pop-ups, banner ads and in-text ads on the Internet that are designed to get your attention and make you click. Due to the way most modern browsers work, there are very few ways for you to get infected with something online useless you click on it yourself. This means you should avoid clicking on banners for offers that are too good to be true.

Make sure your browser is configured to always ask before running files and downloading automatically. If you have to confirm everything, you are much less likely to get infected.

  1. Click the Chrome menu button > select “Settings” > click “Show advanced settings”.
  2. In the Privacy item, tick “Send suspicious downloaded files to Google”

STEP 2: Beware of misleading pop-ups.

Check to ensure that your browser is configured to block pop-ups.

  1. Click the Chrome menu button > select “Settings” > click “Show advanced settings”.
  2. In the Privacy item, select “Content settings…”.
  3. Go to the Pop-ups item, choose “Do not allow any site to show pop-ups (recommended)” > click “Done”.

SETP 3: Clear your cache.

Pop-ups can store information in your browser’s cache, leading to them reappearing constantly. To help prevent this, clear your browser’s cache regularly.

  1. Click the Chrome menu button > select “Settings” > click “Show advanced settings”.
  2. In the Privacy item, choose “Clear browsing date…” > tick “Cached images and files” > click “Clear browsing date”

STEP 4: Stay away from suspicious websites.

As viruses are illegal, they usually hide on other illegal sites. Avoid sites that let you download copyrighted content or other illegal communities. Any clicking on the suspected website or staying on its webpage for a long time could lead to viruses and malware infection.

STEP 5: Install an antivirus program.

An antivirus program will actively protect your computer from viruses by scanning active programs and performing scheduled full-system scans.

As we all know, there are hundreds of antivirus programs but just some are the advanced and effective ones such as McAfee, Norton, KASPERSKY, AVG.

Mind you:

  1. You should only have one antivirus installed at a time in order to avoid conflicts between them.
  2. Make sure that your antivirus is the latest version.
  3. Scan your computer at least weekly, more often if you are heavy Internet user.
  4. An antivirus program is not a foolproof system, and should not replace good browsing habits and common sense.

How to Fix Blue Screen of Death

The Blue Screen of Death, also known as a stop error, blue screen, Blue Screen of Doom, BSOD, bug check screen or Stop screen, is an error screen displayed when Windows crashes or locks up.

The Blue Screen of Death can be caused by both hardware and software issues, and it can be difficult to troubleshoot the problem. Most BSODs show a stop code that can be used to help figure out the root cause of the Blue Screen of Death.

Did your PC restart after the BSOD? If you have the same issue, please refer guide below to fix the BSOD.

STEP 1: Boot into Safe Mode.

If Windows won’t start because of Blue Screen errors, try booting into Safe Mode try fixing the problem.

  • Restart your computer and keep pressing F8 key until Windows Advanced Options Menu shows up, then using arrow key to select Safe Mode with Networking from the list and press Enter to get into that mode.

STEP 2: Perform a Repair Installation of Windows.

This is a quick alternative to completely reinstalling Windows, as it only copies system files to your computer. This is useful if an essential file has become corrupt and is causing your computer to fail.

To perform a repair installation, insert your Windows disc and boot from it. In the setup menu, select Repair Installation. Windows will delete old Windows files and copy new ones. You will not lose any personal data.

STEP 3: Roll back your drivers.

If the cause of the problem is hardware, the first thing you should try is rolling back drivers. This process will install an older version of the driver software, potentially getting rid of the conflict.

  • Open the Device Manager. You can access this by opening the Start Menu and right-clicking on Computer/My Computer. Select Properties, then Device Manager.
  • Click the Driver tab. Select Roll Back Driver and confirm that you want to roll it back.
    Continue using your computer as normal. Once your driver has been rolled back, continue to use your computer to verify that the error does not occur again. Do not update the driver again until a newer version is released.

STEP 4: Roll back Windows updates.

If rolling back the driver did not fix the problem, consider restoring to an older, working installation of Windows. This will let you determine if the Windows updates are responsible for your Blue Screen.

Open System Restore. You can find System Restore by searching for it in the search bar in the Start menu. Open the program, and select a date from the calendar before you started experiencing errors.

This will reset all of the updates and settings to that date, effectively removing any updates added afterwards. Use this to determine if a specific Windows update is what caused your malfunction.

STEP 5: Clear up hard disk space.

If Windows does not have enough space on the disk it is installed on, it can cause system failures. Remove unnecessary files and programs if you have less than 15% of your hard disk free.

STEP 6: Apply new updates and drivers.

If rolling back drivers and updates didn’t work, installing the newest versions and updates (if they weren’t installed already) may fix your problem. Check your Windows Update program to see if there are any new system and hardware updates available.

Click Start and search for “Windows Update”. In Windows 8, tap the Windows key and then start typing “Windows Update”.

STEP 7: Reinstall Windows.

  • If you cannot track down the error, you can try a full reinstallation of Windows as a way to reset your computer. Make sure that you have all of your important files backed up before doing so, as your hard drive will be formatted for the install process.
  • If the Blue Screen is being caused by a failing piece of hardware, reinstalling Windows will not fix the problem. You will need to find and replace the piece of hardware that is causing problems.

Guide to Speed up Your PC Running Speed

Method 1 of 2: Windows

Make Your Computer Run Faster Step 1.jpg

  1. Check your hard disk space. As a rule, you want to keep at least 15% of the hard disk space free to keep the computer running smoothly. Simply go to My Computer, right-click on Local Drive, and go to Properties. There you’ll see a pie chart of your free versus used space. If it’s mostly full, you’ll want to start by removing unnecessary programs and files; if it’s not, you probably want to tackle the actual way your computer operates.

    Make Your Computer Run Faster Step 2.jpg
  2. Remove any programs you do not use. Go to Control Panel > Add or Remove Programs (or Uninstall a Program, depending on your operating system) to find a master list of programs installed on your computer. Some things will strike you as useless immediately, in which case you can remove them right away. Others won’t look familiar to you and may require you some research.

    • It may help to see how often you use the program. If you right-click one of the column titles above your program list (ex. Name, Publisher, Size, Installed On, etc.), you should be able to add additional characteristics by which to judge your programs. For example, find Last Used On on the list of options and check it; a column displaying the last time you used each program will now appear and can also be used to sort your programs. Some programs will not have been used in years and may be candidates for deletion.

    • When in doubt, don’t remove anything you don’t recognize; it may be critical to the function of your computer – and if you delete twelve different things only to discover that your computer no longer works properly, it will be very difficult to determine where exactly you went wrong.
    • Don’t forget to empty your recycling bin.

  3. Prevent unnecessary programs from starting when the computer boots. The more programs try to run while your computer initializes, the slower your startup time will be. Revise your startup programs by altering your system configuration via MSConfig.

  4. Change power options in Control Panel, to High Performance if you have a Desktop PC as it may prevent Hardware Throttling by Manufacturer!

  5. Disable any programs which run in the background. Background applications can take up valuable CPU cycles and ram, so disable the ones you don’t need.

  6. Remove any unnecessary entries from the Windows Context menu. Several programs vie to sit in your context menu, and if you’re not actively using them, disabling them will get your context menu to show up much faster the next time you bring it up.

  7. Install an anti-virus program, spyware scanner, and an anti-malware also Microsoft Security essentials works well. The fewer bugs, viruses, and bits of adware your computer has to manage, the more time it will have to devote to other processes. While you’re at it, make a point of keeping Windows up-to-date; not only will this keep Windows itself in better shape, but some viruses ride in on Windows updates that are downloaded way after the fact (and therefore not monitored as closely).

    • While installing an anti-virus program will actually slow down your computer, malware will slow it down much more. If you’re 100 percent sure that viruses aren’t going to infect you due to your safe computing habits, you might want to disable or remove your anti virus utility.
     Make Your Computer Run Faster Step 5.jpg
  8. Run a Disk Cleanup. This can clean up hundreds of megabytes of temporary files – sometimes even gigabytes (if you have Windows XP, Vista, or 7). It will also open a window in which you can chose what to delete. Go to My Computer, right-click the Hard Drive and select Properties, and then click Disc Cleanup (within the General tab). Check all the boxes except for the game files and setup files.

  9. Get an SSD. Solid State Drives (SSD’s) can complement or replace your hard disk, and they are faster and much more secure than hard drives.

     Make Your Computer Run Faster Step 6.jpg
  10. Run a Disk Defragment. This will reconfigure the way the hard drive stores information for maximum efficiency. Go to My Computer, right-click the Hard Drive and select Properties, then go to the Tools tab and click Defragment Now.

     Make Your Computer Run Faster Step 7.jpg
  11. Check for any disk errors. These will also slow your computer down. Go to My Computer, right-click the Hard Drive and select Properties, then go to theTools tab and click Check Now under the Error-Checking area. When the dialogue box opens, check both boxes.

    • If you get a window saying that Windows can’t check the disk while it’s in use, click on Schedule Disk Check and then OK. It will run on your next reboot.
     Make Your Computer Run Faster Step 8.jpg
  12. Turn off indexing. Go to My Computer, right-click the Hard Drive and selectProperties, then unclick the box indicating that the drive should be indexed. Don’t do this if you actually use any of the Windows Search functionality. The background indexing is what makes those searches fast and Windows is already very good about not getting in your way to do indexing while you’re trying to do something else.

  13. Clear your Prefetch folder. Windows saves a file of the program you are using to make it start up faster. After years of use, this folder gets stuffed with irrelevant programs.

    • Open Notepad and type:
      del C:\Windows\Prefetch\*.* /Q
      Rundll32.exe advapi32.dll,ProcessIdleTasks (Copy and paste this text to ensure you don’t make any mistakes.)

      Make Your Computer Run Faster Step 9Bullet1.jpg
    • Save as faster.bat (the .bat extension will run it as a batch file).
      Make Your Computer Run Faster Step 9Bullet2.jpg
    • Run it! Simply double-click the file to initialize. In a few moments, the command prompt will disappear and your programs should run more smoothly.
      Make Your Computer Run Faster Step 9Bullet3.jpg
  14. Change Prefetch Parameters. This a dangerous task to complete unless you follow these steps exactly. If you’re not sure about anything, don’t continue.

    • Go to Start > Run and type regedit to initialize the registry editor.
      Make Your Computer Run Faster Step 10Bullet1.jpg
    • Go toHKEY_LOCAL_MACHINE>SYSTEM>CurrentControlSet>Control>Session Manager>Memory Management>Prefetch Parameters to access the parameters.
      Make Your Computer Run Faster Step 10Bullet2.jpg
    • Double-click EnablePrefetcher. Once the new window pops up, there should be a small, editable text box with the number 3 in it. (Windows allows 4 options: 0, 1, 2 and 3.) 3, the default, fetches everything.
      Make Your Computer Run Faster Step 10Bullet3.jpg
    • Change this to 2. Your PC will boot a lot faster and your PC performance shouldn’t be affected.
      Make Your Computer Run Faster Step 10Bullet4.jpg
    • Click OK and then close regedit.
      Make Your Computer Run Faster Step 10Bullet5.jpg
  15. Disable any fancy Windows effects. Go to Control Panel>System>Advanced System Settings and click on the bullet which says ‘Adjust for best performance’.

     Make Your Computer Run Faster Step 11.jpg
  16. Add RAM to your computer. To see if you need more RAM, initialize theWindows Task Manager by pressing CTRL+ALT+DELETE. Under thePerformance tab, find the area devoted to Physical Memory. If the Free amount hovers around zero but the computer is still slow, you may need to take your computer in to add RAM or even add more RAM yourself.

     Make Your Computer Run Faster Step 12.jpg
  17. Restart your computer. The computer usually needs to reboot to implement changes.

     Make Your Computer Run Faster Step 13.jpg
  18. Remove gadgets you don’t use. All gadgets that are running slow down your computer.

     Make Your Computer Run Faster Step 14.jpg
  19. Log off the users who do not want the computer. Switch user your account then if you see that many users are logged in, log them off.

Method 2 of 2: Macintosh

  1. Check your hard disk space. As a rule, you want to keep around 30% of the hard disk space free to keep things running smoothly. Simply right-click the Hard Driveicon on your desktop and go to Get Info.

  2. Uninstall unnecessary programs. You can either uninstall them manually ordownload a program to help you sort and delete them. Some things will strike you as useless immediately, in which case you can remove them right away. Others won’t look familiar to you and may require you to do some research.

    • When in doubt, don’t remove anything you don’t recognize; it may be critical to the function of your computer – and if you delete twelve different things only to discover that your computer no longer works properly, it will be very difficult to determine where exactly you went wrong.
  3. Delete files you don’t need. Unless you have very little storage space on your computer or simply have an abundance of unnecessary documents, deleting small files won’t make much of an impact on your computer’s overall function. However, any large files like movies you never watch, photos you don’t need, or songs you never listen to can really gum up the works and should definitely be removed.

    • Don’t forget to empty your trash bin.
  4. Prevent unnecessary programs from starting when the Mac boots. The more programs try to run while your computer initializes, the slower everything will be. Go toSystem > Preferences > Accounts > Login Items. Select any items you don’t need and click the minus (-) sign to remove them.

  5. Repair the disk. Go to Applications > Utilities > Run Disk Utility to repair both the disk and the disk permissions. It’s a good idea to run this once a month or at least once every few months.

  6. Remove unnecessary dashboard widgets. Even if you don’t have the dashboard activated, these widgets can eat up RAM by running background updates while you try to do other things.

    • If you have OS X 10.4.2 or later, simply use the Widget Manager: go to theDashboard and open the Widget Bar by clicking the plus (+) sign; click Manage Widgets and then either deselect widgets to disable them or, if they’re third-party widgets, remove them completely by pressing the red delete button, which is a circle with a line through it, and click OK to confirm.
  7. If you use Mac OS X, download a free program called Monolingual. With OS X, much of your computer’s hard disk is devoted to virtual memory and gets eaten up by language-availability software. Monolingual will allow you to remove languages you don’t use on in order to free up space.

How to Guard Against PC Viruses

Protecting your computer from viruses and other threats isn’t difficult, but you have to be diligent.

  • Install an antivirus program. Installing an antivirus program and keeping it up-to-date can help defend your computer against viruses. Antivirus programs scan for viruses trying to get into your email, operating system, or files. New viruses can appear daily, so check the antivirus manufacturer’s website frequently for updates. Some antivirus programs are sold with annual subscriptions that can be renewed as needed, but many are also available for free. Microsoft offers Microsoft Security Essentials, a free antivirus program you can download from the Microsoft Security Essentials website. You can also visit the Windows Security software providers webpage to find a third-party antivirus program.

  • Don’t open email messages from unfamiliar senders, or email attachments that you don’t recognize. Many viruses are attached to email messages and will spread as soon as you open the email attachment. It’s best not to open any attachment unless it is something you are expecting. Microsoft‌ Outlook and Windows Mail help block potentially dangerous attachments.

  • Use a pop-up blocker with your browser. Pop-up windows are small browser windows that appear on top of the website you’re viewing. Although most are created by advertisers, they can also contain malicious or unsafe code. A pop-up blocker can prevent some or all of these windows from appearing.

    The Pop-up Blocker feature in Internet Explorer is turned on by default. To learn more about changing its settings or turning it on and off, see Internet Explorer Pop-up Blocker: frequently asked questions.

  • Keep Windows updated. Periodically, Microsoft releases special security updates that can help protect your computer. These updates can help prevent viruses and other computer attacks by closing possible security holes. Make sure that Windows receives these updates by turning on Windows automatic updating. To learn how, see Turn automatic updating on or off.

  • Use a firewall.‌ Windows Firewall or any other firewall program can help alert you to suspicious activity if a virus or worm attempts to connect to your computer. It can also block viruses, worms, and hackers from attempting to download potentially harmful programs to your computer.

  • Use your browser’s privacy settings. Being aware of how websites might use your private information is important to help prevent targeted advertising, fraud, and identity theft. If you’re using Internet Explorer, you can adjust your Privacy settings or restore the default settings whenever you want.

  • Turn on User Account Control (UAC). When changes are going to be made to your computer that require administrator-level permission, UAC notifies you and gives you the opportunity to approve the change. UAC can help keep viruses from making unwanted changes. To learn more about enabling UAC and adjusting the settings, see Turn User Account Control on or off.

  • Clear your Internet cache and your browsing history. Most browsers store information about the websites you visit, and information that websites might ask you to provide (such as your name and address). While it can be helpful to have these details stored on your computer, there are times when you might want to delete some or all of them, for example when you’re using a public computer and don’t want to leave personal information behind.
