Process Lists

Firstly, sorry if this is in the wrong section - I couldn't work out where it should go...

Secondly, my fan starting going nuts earlier so I checked with task manager to see what was eating my available memory and I had 3 entries for svchost.exe - I checked with the Windows Process Library and this entry is essential for running .dll stuff, but 3 entries? I got one for the local service, one for a network service and a system claimed one... Does this sound about right? If not, which should I kill off?

Cheers

i have more than that, like 7, and it is essential. kill it, and kill the os untill you restart.

The only reason that I asked was cos I read this on the Windows Process Library:

svchost.exe is also a process which is registered as the Trojan.W32.Dasher. It takes advantage of the Windows LSASS vulnerability, which creates a buffer overflow and instigates your computer to shut down. To see more information about this vulnerability please look at the following Microsoft bulletin: http://www.microsoft.com/technet/sec.../ms04-011.mspx

Wasn't quite sure how to approach it. What do you reckon the chances are that any of them are malware? I ran Spybot S&D, Windows Defender, AVG Free and Windows Registry Repair Pro and none of them picked anything up...
