I recently had a malicious worm located in the "svchost.exe" file. I contacted Symantec (I use Norton Anti-Virus Program) and they advised me on how to deal with it. I did this, but now, whenever I start up my laptop an MS-DOS window opens and a warning box appears telling me that the program could not be initialized and would need to close down. I then close it, and receive no further problems with it. The only problem I do have is wating for it to initialize and fail as my laptop starts up is just plain annoying!
