svchost.exe Is slowing down my computer DRAMATICALLY

Hello, I recently went on a vacation about a week and a half ago, and before hand, I shutdown my computer so there were no memory leaks for my time gone [6 Days].  I came back home and turned on computer which ran fine for a while.  But then my computer started acting up, which it does every once and a while but this has lasted ever since I got back.  Norton is my Anti-Virus, and keeps telling me that "svchost.exe" is using up lots of memory.  I must have at least 15+ svchost.exe processes open for what so ever reason.  3 of which are at high usage [One at 70,000 and the second at 20,000 and the other one at 10,000].  The first two [70,000 and 20,000] are both in the Username category of "System" and the third one [10,000] is in the "Local Service" username category.  I'm in need of help to solving this.  

 I was wondering if it may be a virus/trojan that has affected the svchost.exe program???

It may also be a good idea to boot into Safe Mode and check your memory use
as Safe Mode runs on minimum processes.

Clean Boot is another useful troubleshooting  tool -
How to troubleshoot a problem by performing a clean boot in Windows Vista or in Windows 7

If you find nothing when running via Clean Boot -
While most AV's  are supposed to detect  Spyware  as well as virus/malware
Spyware Search and Destroy  specialises  in  spyware detection, and may be another useful cross-reference.
It would seem that if you have spyware that is using a lot of RAM then it would
also be using some cpu resources as it sends it's information out on the net.

btw - I've never had malware/spyware in  ten years of using a PC (have had
false positives from my AV though), but I don't use torrent sites, social networking, or open any junk e-mails both of which are the main source of  bad stuff.
While  your problem may be something else, virus, etc are known to install when re-booting and can install into the boot sector of the HDD where they are very  difficult to remove.
