Hello Everyone, Thanks very much for all the good help. I had AVG running fine on this Vista system some days ago. Then, I had a problem with an email I couldn't delete. So, someone helped me go into some part of this system and do some configurations I don't understand, 1 procedure was a system restore. After this, I discovered that AVG was no longer on my desk top, or in the system tray. So, I was trying to download it again and again, but to no avail. Then, I discovered something disturbing today, I went into programs and features and was studying what was there. I also went into programs and files, would you know? That AVG was there. I couldn't restore it, or anything. So, I think that the reason I couldn't download AVG again, is maybe because, it looks like I have it, even though its not running now. Any ideas, how to restore it? Or what I should do next? Again, So, Many Thanks, Cheryl
