I installed avira10 latest version after I clean installed my OS. It detects many clean files as virus, worms, trojans. It's so annoying, it detects something frequently now and then. It even detected very simple html file containing my high school marks as some kind of infected file which it detected nothing back then,when used version 9.I loved avira but this latest version... It became so annoying, I couldn't tolerate it and have uninstalled it. I've just downloaded and installed avast free. Hope, it will do good job on giving virus protection and won't be annoying. Anyway, which antivirus do you guys use???
