Couple questions about ESS

I recently upgraded from NOD32 to ESS.
In the ESET folder I notice a lot of the remnants of Nod32. Can these be deleted

CAN/SHOULD I do a scan of the puter from "Safe Mode"? I tried scanning ESS in safe mode but the puter seemed to be frozen. Running Vista Business.
Will try again after posting this msg.
Thanks

 

One problem solved.
I was able to go into Safe Mode and execute the ESS scan. However, I fail to see the advantage of doing it this way. Still got tons of Open file failure.

 

Hi, the ESET folder should have been manually deleted after uninstalling NOD32. At this point though, you don’t have to delete the nod32 files.

The time to run a safe mode scan is if ESS found a threat and was having problems deleting it. Just curious, is there a special reason you ran the scan in safe mode?

 

Not sure if I remember correctly but I think I installed ESS on top of NOD32. That's probably why the NOD32 files were still there. I have since deleted all NOD32 files.
Second problem.
Somewhere on the Wilders forum I read that the ESS scan should be done in "Safe Mode". The reason I tried that was to see if all the files that ESS couldn't scan for whatever reason might be able to be scanned in "Safe Mode". It didn't seem to make any difference.
