Why can't you update your virus definitions?
Adaware doesn't detect viruses, it detects spyware/malware/adware. Just
delete the ones it finds. The ones you list are not viruses.
After a format and reinstall, what comes back? Explain exactly in detail and
post all error messages.
Did you fdisk or just format?
