Slashdot has the dope on it.
I haven’t had a problem with AVG until just recently. The past week or so, it’s had boxes popping up urging me to upgrade to the pay-edition.
I used Avast before that, until I downloaded a questionable file. I scanned it with avast just to be sure it wasn’t infected, and it came back clean. Ran the file… and a huge spyware bomb exploded everywhere. After I got everything restored, I installed AVG, and had IT scan the file, which came back a “OMG Get rid of this thing!” message.
I’m going to give Avast another try, though.
