Antivirus: This year's first choice in PC Mag....

Among the 'freebies' (my old neighborhood!) this one gets the nod as best at doing its thing unobtrusively in the background without a whole lot of semi-skilled twiddling from the nervous user. (That would be me!) And it's small, powerful, quiet, friendly with its neighbors like Malwarebytes, and SUPERAntiSpyware, and you don't get to annoy it with requests for scans, because it decides all that for itself. It automatically updates, and it periodically scans to suit itself, without any heckling from the cheap seats. I like that. You can get it and forget it, and your precious posterior is still adequately protected.
