In Registry: HKU/Software/Microsoft/S-1-5-21-(blabla)/Search assistant/ACMRu/5603, I see entries like 000 *.ject, 008 Gigex speed delivery, 024 gator. Norton, Ad-Aware, and RegSeeker show no identifiable problems, and HiJack This shows nothing out of the ordinary. I there anything to be concerned about? I run with Norton & Zonealarm, and use PestPatrol about weekly.
