I also updated to v8 on XP/SP3 via the GUI with no problems from the process, BUT I wish I hadn't. Now avast is very intrusive and constantly doing unwelcome things like slowing down internet browsing, spinning up sleeping hard drives, it's worse than a virus!
Can I revert back to version 7 and if so, how long will that be supported with new definitions, or would it keep nagging me to upgrade to v8?
Oh, and as a new user of this forum, I find it ludicrous that I have to type a verification code just to post. Do you really hate your members that much? They already had to pass that test to register so it's a redundant burden/annoyance.
