Thread: computer problems

I need computer help.

I have ran ad-aware, spybot, avg and ewido and it catches all kinds of stuff, i'll list a few...
Downloader.tiny.nch
rootkit.agent.ef
downloader.agent.awf
hijacker.agent.jh
downloader.nurech.bh
trojan.kloan
trojan.qhost
prozy.small.osw

the list goes on. But.....nothing has worked, the computer closes pages on its own, shuts down and restarts on its own. I start it in safe mode with networking and i start to type something in the search bar and it closes out. I have been scanning the friggin computer for 3 days now and says it has fixed the problems but it acts up again so i scan it again and same thing...there were 47 trojan horse, hijacker...etc when I scanned it this morning.
I disconnected the eathernet cord from the comp and the damn thing went crazy pulled up over 50 pages in a matter of seconds by itself.

HELP

btw , the PC in question is my kids computer ....need I say more?

Thanks in advance
