One of the signs of malware infection is that your PC starts to slow down. Even if you have the best antivirus software, your computer might still be vulnerable to malware and virus. The best measure is to remove the malware from your windows PC. We will give a step-by-step guide on how to safely remove the malware from your PC.
1. Enter safe mode
First step is to disconnect your PC from the internet to prevent the malware from spreading to your hard disk. After that you can boot your PC into Microsoft’s Safe Mode. Malware will stop running during safe mode and it becomes easier for you to remove them. To boot into safe mode, you need to reboot your PC, but you need to press SHIFT key before you click reboot. When the menu pops up, select Troubleshooting -> Advanced Options -> Startup Settings. On the next window click the Restart button and wait for the next screen to appear. Then select number 4 from the menu which is the Safe Mode.
If you find your PC runs faster in Safe Mode, It is most likely that your PC is infected by malware.
2. Delete temporary files
Before you run a virus scan, you need to delete your temporary files to increase the scanning speed. Type “Disk Cleanup” in the search bar and use the disk cleanup utility.
3. Perform virus scan
Download latest antivirus software that is different to your current one because your old virus scanner could not detect the malware (that’s why your computer was infected). We recommend using a popular and highly rated antivirus software such as: BitDefender, Malwarebytes or Avast. You can use any of them, but we will use Avast as an example. Select “Scan” from the left menu and do a full system scan.
Once the scan is complete, Avast will show you the result. Follow the instruction to delete the malware. Try other software if Avast could not scan any malware.
4. Recover files if Windows is corrupt
If you can’t remove the malware (chances are rare), you will need to reinstall Windows. Before formatting your hard drive and doing a clean reinstall, make sure you have backed up all your files and software. Once you have backed up everything, you can boot your PC from Windows 10 installation CD/USB for clean install.
5. Clean your PC regularly
You should use the latest version of antivirus software to do virus-scan regularly. It’s better to get the yearly subscriptions as they provide more features. However, you can also choose the free version such as Avira Antivirus and Bitdefender Antivirus free edition.
