you can try my download for some of the common problems...

Look for the Microsoft utility or unhooexec.inf as suggested by Vikram.
U can use SEP Tool to analyse the issue.

I've seen all the links you all have posted. I'm just wondering if Symantec has anything else.
The techs here also has a batch file of restoring the registry and removing well known virus from the C:\
I don't know where they got it.

 Its all available on the Internet...However Symantec doesn't have any such tool..
The most Famous of these tools are HijakThis which Trend bought it few years back.

I just thought it would be a great idea for Symantec to develop their own tool. This would be useful for installing on a new machine. At least just check if the necessary registry values and files are in proper order. Given the experience of having to wait for an installation to finish only to see it rollback like some malwares do.

Maybe the support tool will do for now. :D

Its already there in Idea's section..

Every so often I run across a virus that won't let me execute anything on the PC. No task manager and certainly no AV / Malware removal tools. And if I find the malicious files and try to remove them, I always get "access denied" Usually safe mode does the trick but this is almost impossible when I'm doing this remotely and there is no local IT support. I found a cleanup tool that consists of the cleanup.bat and cleanup.reg. I'm just curious on what reg keys the malware hijacks to cause this and if i can manually remove. I suppose all malware works in different ways but it has to be hijacking most of the same keys?
