I've been trying to uninstall avg free with no success.When I try to uninstall I get an error code 0xC0070782 and it says it can't complete the process. I can't update the program and it will not reinstall. So it's just sitting there and I can't use it and I can't get rid of it. I'm using windows 7 on my desktop with a 64 bit os. We are not tech saavy people but this is the first trouble we've ever had with avg and we've been using it for years. The avg site says to download their removal tool but I'm skeptical of that as well. When we tried to reinstall it we ended up with avg zen and had to do a system restore to get rid of that. Any advise would be appreciated
