A friend has a windows 7 (not sure of exact flavor) that is running the paid version of AVG ( 2011 I believe ) and it says it has found a rootkit in DFSC.sys but cannot clean as it is a system file. He ran some other scan he found online and it removed about a dozen things but it still reports same. I have run dss and have yet to post to that forum as it also says to run gmer... which has been running for about 4 hours is this normal? I haven't had to do anything like this since the days of Hijackthis logs...several years ago....I'm wondering if something is keeping gmer from completing or if there is something else I need to check/do...

Thanks for any help you are able to provide.

Hello and welcome.. Yes this needs special attention to safely remove without killing the PC.
We need a deeper look. Please go here....
Preparation Guide ,do steps 6 - 9.

Create a DDS log and post it in the new topic explained in step 9,which is here Virus, Trojan, Spyware, and Malware Removal Logs and not in this topic,thanks.
If Gmer won't run,skip it and move on.
Include a link back to this topic.

Let me know if that went well.

OK, should that topic get closed you can PM me to re open it,

Now that your log is properly posted, you should NOT make further changes to your computer (install/uninstall programs, use special fix tools, delete files, edit the registry, etc) unless advised by a Malware Removal Team member, nor should you continue to ask for help elsewhere. Doing so can result in system changes which may not show it the log you already posted. Further, any modifications you make on your own may cause confusion for the helper assisting you and could complicate the malware removal process which would extend the time it takes to clean your computer.

From this point on the Malware Removal Team should be the only members that you take advice from, until they have verified your log as clean.

Please be patient. It may take a while to get a response because the Malware Removal Team members are very busy working logs posted before yours. They are volunteers who will help you out as soon as possible. Once you have made your post and are waiting, please DO NOT make another reply until it has been responded to by a member of the Malware Removal Team. Generally the staff checks the forum for postings that have 0 replies as this makes it easier for them to identify those who have not been helped. If you post another response there will be 1 reply. A team member, looking for a new log to work may assume another MRL Team member is already assisting you and not open the thread to respond.

The current wait time is 1 - 5 days and ALL logs are amswered.

To avoid confusion, I am closing this topic.
