Last night AVG kept telling me I had a trojan, so I tried to fix it myself and have completely nuked my computer. I found how to do it online, followed the instructions exactly, and after 3-4 hours of searches, fixes and general stress it rebooted.
And refused to work correctly.
The computer wouldn't connect to the internet, everything went very slowly, and I've spent the last 8 hours trying to fix it.
I tried restoring what I'd moved to quarantines, ran it in safe mode, ran it normally, no joy anywhere.
So I've backed everything up and I now just want to restore it to Factory Settings. Problem is the F11 pressing/holiding F11 isn't bringing anything up, and the Restore System option won't work either. I get the feeling there isn't a system restore installed, and as the computer came preinstalled I have no recovery CD.
Really need some guidance here, hope someone can help?
Computer is an "HP Compaq dc5750 MICROTOWER BU ALL"
I have the 'hp s/n' and the 'p/n' written on the case (Although I don't know what these are?).
I also have the "Microsoft XP Home Edition" product key, or at least I have all but half of three of the numbers. Pretty sure I can guess them as the label has worn off slightly, but assume I have it.
Currently I'm on my laptop, which accesses the internet fine and has no problems.
The PC seems to load up fine but some programs don't function and the network connection doesn't register at all, the error message from 'Network Diagnostics for Windows XP' read...
"Windows has detected a problem with the Winsock provider catalog on this computer. This catalog allows programs to communicate with the computer across a network. Would you like Windows to reset the catalog to the default configuration?"
...which I've tried several times without success.
Any further information required, please shout! Thanks in advance to anyone who could help...
