We need the exact message.Blah blah tells us nothing about the program and if it is a windows app. or malware. Also need to know about NT. Is it NT4 and what service pack?

Hi noelckc,

You're getting that message because you still have some malware on your system. I looked at your log posted here:
http://www.bleepingcomputer.com/forums/ind...topic=46952&hl=

Wait til Grinler declares your log clean before you start asking for other help. Grinler is one of the best.

No big deal, I know this may not seem related so just as a explanation, this line in your log is what's causing the problem:

O20 - Winlogon Notify: winopn32 - C:\WINDOWS\SYSTEM32\winopn32.dll

That is a registry key that allows this malware to start when you log in, it essentially has hooked into Windows itself, and conventional removal methods don't work. Stick with Grinler's guidance, tho, and he'll find a way, it just may take a few more tries.

1) It depends on your computer. Why P-III 500mhs with 512mb RAM does. But I have friend with a Dell 3.0 2gig thank never slows down no matter what he runs.

2) We have new members that have just found the site, but have been IS\IT professionals for years. It will depend on the advice. We monitor e forum very closely. While we may not know the answer, we came usually tell when someoneis speaking f something they know nothing about or just made a mistake. We usually correct te bad information, and on occasion put the entire post or even the enire topic.

If at any time you feel you have been give bad advice or been wrongly treated, please contct a staff member and make them aware of the problem. We cannot correct a proble if we do not know it exsists.
We are here for you not the other way around.

In regard to your first question, assuming you are talking about a full system scan, then yes it will make your PC performance lag. Just like running a scan with your anti-virus. I would recommend that you not do anything with your computer when you run such scans. Go out and walk your dog or something.

As a matter of fact these scans are most effective if you run them in safe mode--without networking. Because some of the malware that may need to be removed is running in normal mode which makes cleaning it up more difficult. And no networking because some malware will communicate with its servers and may be downloading more malware to an area already scanned.

Something else I've noticed in your log that will slow your PC's performance down--you are running two antivirus--Avast and Nod32. This is never recommeded because AV's are heavy on resources and can cause several other problems that can actually reduce your security. And I would think even with a screaming fast PC. You really need to choose one and uninstall the other. If you've paid for Nod32 I would suggest keeping it as it's highly rated among security experts. Avast is fine too, and it's free, so the choice is up to you.

I only mention this because Grinler handles a bunch of logs and focuses on malware, so he could miss this fact.
