How To Remove Viruses From A Computer

The best way to protect yourself online is with a solid firewall, as well as a frequently-updated antivirus program. However, if a virus has infected your computer despite these precautions, don’t panic! Follow the instructions below to remove viruses and rid yourself of those malicious threats.

If you have antivirus software installed, it should alert you to the presence of viruses or malware. If it warns against downloading something, follow that advice if you are unsure of the original source of the download. You can also follow these steps:
