I run windows xp, and, well, let me describe the problem(s) from the beginning. I have several accounts and I noticed this passed week that sometimes, when I started windows, I was unable to login into my account, because the password window just wouldn't come up. I thought "oh oh, virus/malware trouble???" Until then, I was only running the free version of AVG, so I decided to get serious, and foolishly rushed ahead without further thought: I installed the pro, paying version of avast, without uninstalling avg first. Now even when I can login, well first my computer looks busy starting up, with the sand-timer thingie showing up, but it never gets to the stage where any icon shows up at the bottom right of my screen near the time (sorry for my lack of technical terms, I can't remember what that bar is called). Then whenever I try doing anything, my computer just hangs. Once I succeeded in checking what processes were running, and there didn't seem to be anything running, not even avast (ok so some small numbers would flicker on near different things every so often, too fast for me to read, and then go back to 0). And then it froze anyway (I'm using another computer right now). Since it's abundantly clear that I am clueless what I'm doing, I thought I'd better stop and ask for advice... what should I try to do? I'm thinking maybe uninstalling either AVG or Avast...??? Assuming I can get that far that is... Or would it be wiser to just seek professional help right away before I cause further harm?
Thank you so much for your help.
