I downloaded spyblocker from cnet and when it finished I found this new program called cnet download manager. ??? Since this my CPU runs 99.5%. I ran HJT and found only rundll32.exe and the cnet related objects. I "fixed" these and rebooted. The CPU continued to run at 99.5% and I then did C+A+D and found the rundll32.exe running at 99%. I proceded and terminated the rundll32.exe and CPU fell to 2%. Now the system idle process seems to run at 97%. I tried to delete the cnet manager via add/remove but it hangs up even after 5 minutes. I have ran adware6.0 and spybot both of which were updated. Now for the bad news norton firewall and NAV have been disabled w/o my authority???. I am unabe to get them turned back on. I am running Zonealert as a backup. I am also running a virus scan using one of the online virus scans. Gentlemen ant assistance would be greatly appreciated.
