that you have at least Windows XP in which case you have access to the 'system retore' function.
what you have fallen victim to is what are called 'rogue' AV, which tempt you into using them to scan, advising you that you have X# of viruses, and telling you to buy their product in order to fix and taking control of your PC while you are at it.
System restore to the pont b4 you got started on this journey will restore you PC to b4 the madness.
I had a virus on both my computers - i finally fixed one computer. I was going to try the same remedy on the 2nd computer so I rebooted. I was asked for username/password - then the wallpaper appeared but the desktop/icons do not. I tried rebooting, tried again and I even waited up to 1.5 hrs to see if they would appear. When I do ctrl+alt+del the task manager is disabled. I have tried rebooting in "last config" mode - still the same and it will not let me reboot in "safe" mode (it doesnt recognize domain?). I have read several postings online and someone suggested ctrl+alt+esc to access task manager - that does nothing.
Just some background - the virus i had on my computer (which appeared to have been removed) it kept telling me i had a security virus and to download software (i did not) and there was a red circle with a white X in the center on the bottom right hand on my screeen. After running AV i finally got rid of the messages and the red circle but my computer was still not really running properly.
I would appreciate any suggestions and I am not super-techie so any advice please provide step-by-step instructions
Also, I noticed a lot of people answer by telling people to download stuff - please remember i have NO access to my desktop.
Thanks so much!!
