If you are not on dialup, you can disable that.

Info here:  http://www.bleepingcomputer.com/startups/DSC.exe-1245.html

You can use msconfig to do that:  http://www.netsquirrel.com/msconfig/msconfig_win7.html

(Sorry, for some reason I cannot post live links at Dell today.)

The links are not working--it id not show in my previous post. --sorry. 

DSC.EXE could also be the dell suport center file. You can research this here.  I also have a XPS 8100 and do not see this running in the processes.  

I do not recommend the Computer Hope website as posted above.

The OP did not include enough information. If it is Dell Support Center, it should be located here:  C:\Program Files\Dell Support Center\GS_Agent

Here is a link to someone else who had a similar problem.  This may or may not be your problem.

There's no way of knowing unless we have more information. :emotion-42:

bestis1980, you have replied to a topic that is several months old.

I would suggest that anyone having a malware problem post on the Malware Removal Forum.

Often the more you fool around trying to clean something by running general scanners, the more you are at risk of making things worse.
