OK! well my computer is running vista on 1gb, and I'm AT ALL TIMES using at least 80% of the physical memory. When I'm doing other things, it goes way up. Anyway, so I was interested to see what was doing it, so for the first time, I clicked the "Show processes from all users" button. AND to my dismay, there are 16 processes entitled "svchost.exe" with the description "Host Process for Windows Services". They range from taking up 172k of RAM to the largest, 36000k of ram... Is this a virus or what? I have CA Internet Security Suite (I know, not the best thing ever made)... but what should I do? They are all under either SYSTEM, NETWORK, or LOCAL.
Not a virus, my computer usually has 4 or 5 at a time too, the largest usually anywhere from 5000 to 25000.
Run a virus scan, because svchost.exe can sometimes be a trojan. If nothing is detected, go to Start > Run > msconfig and then turn off Startup Services you don't need. If that doesn't help, get more RAM or downgrade to XP.
That seems very excessive there is obviously something wrong. Id just run a virus scan.
If you end one it'll freeze your computer, I don't think they are viruses.
I've just ended some of those processes with no ill effects, but I wouldn't advise it. I've had several running at the same time before, but never 16.
Why Are There So Many svchost.exes Running?
If you've ever taken a look at the Services section in control panel you might notice that there are a Lot of services required by Windows. If every single service ran under a single svchost.exe instance, a failure in one might bring down all of Windows… so they are separated out.
Those services are organized into logical groups, and then a single svchost.exe instance is created for each group. For instance, one svchost.exe instance runs the 3 services related to the firewall. Another svchost.exe instance might run all the services related to the user interface, and so on.
edit:^^^ NEVERMIND! thanks man!

THis is your problem here.
Not a virus.
Either get more ram or downgrade to xp.
You will find it VERY hard to get good performance out of vista with 1gb ram.
Can I upgrade RAM myself? I have 512MB and I don't mind formatting my hard drive...there's around 30GB of stuff on my computer I can't find, as in I only have 50 GB of music, movies, programs, etc yet my hard drive's almost full.
