Hello, i usually got 6 instances of svchost.exe running. While 5 of them are using about 4000 kb of memory, the other one uses more than 20000 kb and when it gets over 25000 kb an error of Generic Host Process for win32 appears which cuts the internet connection and disables sound. Im pretty sure i got no virus, also i checked similar posts but none was able to solve my problem, what can i do?

On a side note, ive been checking about the generic host process for win32 error and it seems i found a solution for it, but since then one instance of svchost.exe uses 45000+ kb of memory, is this ok?
