Review by polarvista: every time I log into vista under a different user, an error pops up stating that only one instance of the AV can be run at a time. What's the use? I can't tell other users to make sure they shut it down when logging off!! If they don't then the next user is causing the system to be unprotected. other than this, the AV worked until last week when the update crashed system! cpu at 100%? used system restore to fix. errors pop up saying files in AV are corrupt and need updating? would like to get rid of it now but after reading the other posts, that might be a nightmare!

I checked all of c: to make sure it was completely gone and only found one other folder and it deleted fine. I hope it works foe you guys also.

My computer is shutting off without cause, when it does boot back up, I go to log in via windows and tells me it's unable to let me in, even as the administrator. There's nothing else on my computer to cause this, it's less than a month old and I haven't downloaded or installed any programs that are web based until today, and have had nothing but problems. It wont let me uninstall, it gives me a runtime error, and past that, when I called their customer service they were less than helpfull telling me I need to provide a screen shot, but I'm not hooked to wireless internet on my lap top which is ha...
