I doubt you have an virus attack your svchost...
Then you wouldnt be able to post on here since it would be attacking your programs that are active.
Press ctrl + alt + esc and tell me how much process's memory is being used up.
Also only the REAL program would pop up in services in also so look for "svchost.exe".
Tbh why do people use such weak programs like this any way...
Rats are the way to go
