What antivirus software do you use?Watch
Yet to have a virus it hasn't blocked, as well.
Windows Defender is another great choice (Microsoft has improved it a lot now) as well as Avira and Qihoo (best free option IMO).
Used to be an avast and AVG user but their recent versions have turned into bloated software with performance issues and mediocre protection.
