infected ccsvchst.exe

hope this is the right place

 

it seems that this is a common problem. When i turn on the laptop and log in i get the message that the ccsvchst.exe is infected. I can't open anything, delete anything or even load for usb or dvd. Basically i can't do anything. It keeps saying i don't have the right permissions.

 

It runs the scan automatically and comes up a list of trojans, viruses and other lovelyt things that seem to be infecting my system.

 

i know there's alot of things about this and i've read them, and i'm still a little confused.

 

Anyone give me clear list of things to try to solve this problem.

 

cheers for any help
