whenever i start my computer and it goes to the login screen a message pops up giveing me the Svchost.exe-Application error. and when i procede to login i have no desktop and only AIM seems to turn on. my virus program Avast is also unable to provide me with a sweep because i am unable to open the program. I am on my other computer posting this because internet is also unavailable along with other programs. Help would be extreemly appreciated.
