How to clean up your Windows 10 PC of viruses

There’s a simple and easy way to remove malware or viruses from your Windows machine. If you are new to computing, or if you don’t have any third party security software, you can use Microsoft’s Windows Defender program to keep your PC clean at all times. 

Before we proceed to the main topic though, we would like to remind you that we accept requests for assistance regarding their Windows computers. If you have a problem that you can’t seem to find a solution to, send us your issue by following the link at the bottom of this page. Just remember, windows problems can sometimes be difficult to diagnose so kindly make sure that you give us very detailed description of the problem. You want to mention relevant history that may have led to the issue. The more information that you can provide, the higher the chance of us diagnosing the issue more efficiently. We also expect that you mention whatever troubleshooting step/s that you may have done before contacting us in order to prevent repeating them in our article. Again, the more details you can give us, the faster it is for us to pinpoint the cause and its corresponding solution.

How to scan your Windows 10 machine for viruses

  1. Right click on the Start menu at the lower right hand side of the screen.
  2. Select Control Panel from the list.
  3. Set the View by panel to show Large icons or Small icons.
  4. Find Windows Defender and click it.
  5. Click on Update tab.
  6. Click Update or Update definitions button.
  7. Wait for the application to download and install the new virus definitions. Virus definitions are files needed by Windows Defender to identify old and new viruses identified by Microsoft.
  8. Once the updates have been downloaded and installed, click on Home tab.
  9. Under Scan options panel, select Full.
  10. Click on Scan now button.

Wait for your machine to finish the system scan. If there’s a detected virus or potentially malicious software, Windows Defender will alert you about it. You’ll then be given options what to do with the detected item. Depending on the size of your hard drive and the speed of your computer, a Full scan may take hours to complete. While it may take that long compared to a quick scan, Full scan option performs a more thorough search in the system so it’s a more effective way to detect viruses. We suggest that you do a full scan when you are not using your computer, like when you’re about to sleep. That way, you can leave the computer do its thing while you rest.

If you have a slow system and you perform a Windows Defender scan, your machine’s performance may suffer horribly so try to do it when you’re not using the computer.

Try using other security software

While Windows Defender is a pretty decent malware detection tool, it’s also good if you can add a third party antivirus or security software to enhance your computer’s defence. There are many reputable security software that offer a trial version of their products so take advantage of such software so you’ll know their strengths and weakness. Just don’t forget to uninstall the unused security software if you’re planning on replacing it. Having two antivirus or security software running at the same time can cause problems on your machine. Don’t worry about Windows Defender as third party antivirus will automatically disable it so you don’t have to do it yourself.

Prevention is better than cure

When it comes to computer viruses, it’s best if you take smart, precautionary moves to prevent them from infecting your machines in the first place. Some viruses are designed to scan for security software first and disable them so they can have free rein afterwards. If you’re not careful with what websites you visit, or what files to download, you’ll most likely fall victim to malware. Avoid using pirated or cracked software and always be mindful of things you click online. If you get a pop up in your browser telling you that you won something and it’s too good, it’s probably a scam. Never click on ads that pops up on your screen. They’re usually the first step towards infecting your machine with a virus.
