Can you recommend a free anti-virus aside from AVG and Avast? Right now our home desktop is using AVG but there are issues like the computer had markedly slowed down and the booting takes eons. With Avast, it's not very slow but there are software that would run properly. Our desktop used to be fast when it had the Symantec anti-virus. However, the license expired in 2015 so we resorted to a free downloadable anti-virus.
