trouble with viruses and trojans and command prompt?
A few days ago I started to have a lot of trouble with my computer. Command prompt is opening by itself, usually two windows at a time, and then an error pops up and closes them. Why is command prompt opening? Is it dangerous?
Another thing, I always use firefox [latest edition] and never ever use IE [for many reasons]. Now though, I'm getting pop ups that open in IE, stuff like 'crush calculator' or that pop up that says to run a system scan. Yeah, I exit out of them.
I ran AVG free edition and it detected some threats labeled 'virus lop', so I moved them to quarantine, but now when I start up windows I get an error "rundll" or something like that, is this something I need to be concerned about?
I'm getting a lot of errors with stuff like 'winlogin' and 'explorer.exe' and 'ctfmon'. I have been trying to get screenshots but my computer has been restarting automatically when these errors show up.
AVG also found some trojans and removed them.
I'm on my college's internet connection.
I'm running Windows XP and my computer is about 5 years old and getting kind of low on hard drive space [I don't know if that matters with this problem though].
I have to get through the rest of the school year with this computer. It ran fine until this started happening, now it's slow and error-ridden. :(
My main question is: what's the deal with command prompt opening without me doing anything?
and
is there anything I can do, besides run AVG, to figure out what's going on with my comp and how to fix it?
I'm not the most tech-savvy person, but I'm not completely ignorant either [at least I hope I'm not that dumb haha], so is this something I can fix on my own?
thanks to anyone who reads this and helps.

Well, you know this type of virus that you are describing is probably a Troajn.vundo or a Trojan.Hachillem or an adware.win32.intdlim345 or a spyware.Go to the site below and follow the instructions below too.

Download Spybot. Its amazing.
Search for and download updates. Run the immunization, then search for problems. Let it eat whatever programs it wants.
Also, you need norton antivirus. I wish I still had the link to the corporate edition, it doesnt require subscriptions.
Now, back up important files. Pictures, documents, etc. Anything you can re-download doesnt fall into this category.
If your computer isnt fixed, I recommend a wipe. About every 6-8 months I back up everything I have thats important onto CDs or an external hard drive, and reformat and reinstall windows. It gives you a clean slate to work off of. Thats pretty easy, you just put in the windows installation cd, boot from the CD, and reformat your hard drive.
If it helps, I'm in your position. I'm running a laptop that was top of the line about 5 years ago. I have to be very careful these days because my CD drive died about two months ago. Save for a new computer in the meantime.

Yes, you should be worried. You are missing important windows files, probably because AVG deleted them. You have mutliple kinds of malware. Your are probably running a lot of unnecessary programs which are slowing down windows. What I do when I get multiple problems like that is just completely reinstall Windows. That fixes all the problems.
Follow my guide for unexplained popups and then my guide for speeding up windows:

If you still have any problems, post on a malware removal forum:
That should get your computer cleaned up pretty well, but the best solution would still be to reinstall.

Some of these are vital windows exe's that obviousley are missing the path they need to run correctly, also I had a similar virus that attacked my computer, and it restarted pretty much over anything, even during playing a game, You need to flatten your computer, make a back up dvd disk of everything you want saved, but ONLY save music and pictures, and reinstall XP, use automatic updates, and run AVG at the end of everyday, leave it overnight, if it should find anything, find the path of the threat, go to start, run, then type the path in and delete the file.
