Review title: Corrupts hard drive
Product review: I had used Norton antivirus 9.0 without problems, although it never found a virus except in a few old files the first time I ran it. When it ran out of time (1 year) I got 10.0 and regret it. It hangs up the system requiring restarts and cleaning up with diskaid and Norton Disk Doctor, which has not fully resolved the problems. Don't buy it.
