Hi all, this is my first post here (hopefully the first of many, not on this thread though). My computer was infected with a virus recently (anti virus 2008 and perhaps more) I did not install this thinking it was anti virus software (I know better), though it installed itself. Since then my desktop background has changed into one saying that i have a virus (a fake alert basically). Since then every time I switch it on, it starts normally until it starts to load the desktop, it shows my desktop with a black background (it's not normally black) with the fake alert after this my computer restarts again and this is continous never reaching desktop. I have a HP but that F10 trick doesn't work, I don't have a boot CD or floppy dick (my computer is quite old), and I can't boot using the windows XP CD (I only have a copy, not original). I can't do any virus scans because I can't go into desktop, safe mode doesn't...In fact none of the advanced options work and if i select debugging mode the computer just freezes, if anyone can help (other than saying take it into repairs) I would be most greatful. Thank you.
