in the last year I've gone through a ton of antivirus programs.I have generally used avast free for years with little issue until it started to cause problems with a vmware application I needed to use.Since then I've tried avira.but I scrapped that last week when I got a bad Trojan,first I had in years.Im currently using bitdefender 2015 because I got a free 8 month licence,but I'm interested to know what antivirus people are using at the moment ? I usually go by av-comparatives recommendations and I prefer a free option
