Till today I was using the AntiVir PersonalEdition but the latest upgrade to version 7 made it very fishy. All configuration options for the automatic updates are basically gone, it tries to update itself whenever it wants (thank you, dear popup window, I really wanted to know that while playing LFS), it reports that it might be out of date EVERY fricken day (even though I set it to report every 7 days) and reaching an update-server is pure luck since the version upgrade.
In my point of view it starts to go down the road of all the other "big" AV companies like McAfee or Norton which I really don't like. I have to admit, it once indirectly saved me from a virus attack (which came over from the network share of a, lets say a bit careless friend), but it wouldn't have saved anyone with "standard" computer knowledge because it didn't actually do anything against the process that spread the virus, it just started reporting more and more infected files. I had to kill the process, and thank god I was fast enough so it only got 10 files. It completely trashed the system of my friend though :rolleyes:
Whatever, goodbye free AV, welcome Avast.
