For over a year I could not do any updates on my laptop because of this Avira antivirus error. It left me totally frustrated, I tried to find it to uninstall, couldn't, and I knew I sure in the hell didn't install it, so it just got left wherever it was hiding because I am not a great techie person and because everything I googled every month or so to fix it left me more confused or if I was able to follow along, absolutely nothing worked.
Finally my windows became so unresponsive and outdated I knew I had to either throw my laptop away. pay some kid a million bucks to fix it, or give it one more try. Lucky day for me, I found the above information, applied it (easy to follow directions), and BAM, it worked like a hot damn. Got all my thousands of updates in and my laptop is working 100% Best site ever !!!!!!! Thank you, thank you ,thank you!!!!!!!! (This comment required lots of !!!!!!!)
