Best of the antivirus programs IMO At the time of AVG version 4,which messed up my monitor settings to the point I thought I needed a new monitor or new driver or new computer...I took out AVG and went to Avast which felt clunky. Monitor problems remained. I tried Avira and almost immediately it told me my monitor settings were wonky and do I want them fixed? Yor N? It is the first program that saw that issue. Norton did not see it either as it slowly did a pc scan.. That sold me right there. That has been years ago and every once in awhile I check my computer with another AV just to see what it sees. When there are no bugs then I guess the program is doing its job. Can't be happier.

Avira is the best antivirus program I've used. I'm keeping it, I just don't install the optional extras
