Word of Warning

For Microsoft Windows, Windows Defender provides totally adequate virus protection in most cases. These tools are intended for single-use in detecting/ removing threats on an infected machine, and are not recommended to be left running in the background, use portable editions where available.

Many anti virus products have a history of introducing vulnerabilities themselves, and several of them seriously degrade the performance of your computer, as well as decrease your privacy. Never use a free anti-virus, and never trust the companies that offer free solutions, even if you pay for the premium package. This includes (but not limited to) Avast, AVG, McAfee and Kasperky. For AV to be effective, it needs intermate access to all areas of your PC, so it is important to go with a trusted vendor, and monitor its activity closely.
