Should have been more clear. Sorry. I installed avast when my McAfee subscription expired. All was fine, but knew I needed to remove McAfee and did so. After I used windows xp uninstall, the next time I booted my pc and ran avast, avast found the trojan and cleaned it. at that point I was unable to access the internet because the pc could not renew the ip address. I attempted to manually renew the ip with no success. The pc has no internet access and has been loosing other capabilities as well. It no longer recognizes the DVDRW/CDRW drive as that. It recognizes the CDRW drive as a CDR only. It will not boot from either the CDRW or the DVDRW. Since I have no internet access I am unable to download any fixes or run any scans using online resources. anything that is suggested, I will have to access on another pc and move to the infected one using a thumbdrive, the only thing that is still working! Sorry! I am a bit frustrated at the moment.
