I have Windows XP SP2 and in task manager I have 6 "svchost.exe" (without quotes) s. Three of the them are under username "SYSTEM", two of which use about 5 mb of memory each and the other one using about 17.5 mb. Two of them are under username "NETWORK SERVICE", using about 4 mb each. The last one is under username "LOCAL SERVICE", using about 4.5 mb each. This seems like a lot, and it seems more after I have been infected by viruses/trojans four days ago. I am not sure if it really is more though - it just looks like a lot. Any comments will be appreciated.
