Man. He's talking about FREE antivirus. And out of free ones, MSE is best.
No.
Last night my sister gave my her laptop to fix. Had 3 viruses on it. Guess what AV... MSE.
I did a MSE scan, found a few "tracking cookies" on her computer. Didn't find the viruses. Removed MSE, installed avast. Ran a scan. Found Viruses. Gone
I copied the infected files to a USB drive, plugged into my PC. My AVG detected them straight away.
Results speak for themselves.
