so in the 24 hours or so since i first got the program, and updated it, it has updated the database 7 more times?
Essentially yes, that doesn't necessarily mean all the updates were offered one at a time.
I find it very unusual that the scan would take 8 hours, there must be something slowing it down. How large is your hard drive?
A full scan for me takes about 1 hour. I have seen them take a couple but honestly not 8 hours. Can you tell me, is it actually scanning all the time or does it seem to freeze? They are currently examining a possible issue with freezes during scans which might be cause by Zone Alarm firewall, they are not certain at this point but it is a possibility. The scan should never take 8 hours.
I wasn't meaning to be critical when asking if you had rebooted, it is just that many people don't understand they must reboot if the log says -> Delete on reboot. They will run the program and then immediately run HijackThis without rebooting. We have to ask to be absolutely certain.
