While I had AVG protection on my computer I was attacked by hackers claiming to be Microsoft. They froze the computer and told me it would be permanently disabled if I didn't correct something that they would correct for me. I figured out that it was a scam but not before I allowed them to remotely control computer for five minutes or so. I then contacted AVG as to why I was hacked when I am paying them for protection. They told me I had let the hacker into the computer so they were not responsible. They told me it would cost me $200 for them to fix some corrupted and missing microsoft files that the hackers had created. They refused to take responsibility for allowing the hackers through in the first place. Besides this, they never stop popping up with sly ads for upgrading your service designed to look like alerts that you have a problem. If you don't respond you start having virus like problems on the computer.
