I'm Infected. Please help

[jmmessin]

Other than my computer seems to run a bit slower, I don't seem to have any visual or other performance problems with the computer but I noticed in the "hijack this" log that there is an entry which doesn't look right; O18 Filter Hijack.
I ran the 8 steps and created the 3 log files. Please review these logs and advise.
Thanks

Its better

I ran combo-fix and it fixed the O18 entry. What does this entry mean? Is this something I need to worry about?
I need you to review these log files attached and advise on anything else to fix.
Thanks so much.

The 018 entry was bad, do you want it back?

Lets remove these entries from the hijack this log:

Fixed everything except two

I checked and tried to fix all the ones you suggested.
However, there were two which did not get fixed. It appears like my McAfee Antivirus blocked it based on what is in the log file. I'm attaching the "AccessProtectionLog1-28-10.txt" which shows the blocking and another "hijackthis" log.
What do I do next?
