AVAST Horror!!! Please help???

In reply to: See if this helps by roddy32 

I downloaded Avast yesterday b/c my Norton expired and I couldn't afford to pay another term. Avast was a nightmare!! I couldn'tbelieve how it kept popping up this active "on scanner" window on top of my window, on top of whatever I was looking at, just totally in the way and on top of everything - and it went up and down and kept animating all over my screen!! I'm like, what the....... So I tried to go in settings and figure how to stop it, nothing seemed to work or be the answer. I said to heck with this and tried to "uninstall" it - and wouldn't you know, it was impossible to uninstall AVAST. It does NOT come with an "uninstall" button, and I could NOT uninstall it through my "Programs/Features" on my Vista PC. It froze itself on my c'puter! That sickens me......it's stuck on my PC along with another AV program (AVG by the way, which I've used 2-3 yrs ago and was always happy with). My God I've never been so annoyed (well, yes actually I have) at an antivirus/spyware program for forcing itself to stay on my PC when it's totally unwanted! Any ideas? I don't even want to see that little ball with the "a" in it on my taskbar anymore! Thanks for anything that helps!
VH - so sick of annoying programs that won't politely exit.
