The other day I was using my computer online when a load of clicking noises started. I immediately shut down the window but since then, my AVG has picked up 5 trojan rootkit-agent.DI's and gives the object name as "C:windowssystem32driversndis.sys". Also, my task manager shows that something called SVCHOST.EXE is running the hell out of my CPU at a startling 99%.

Can anyone please help. My laptop has slowed to an agonising crawl- seriously, it's like being in a really old bus going up a very steep hill!! I have tons of work to do this weekend and Christmas is coming (Boo Hoo).

Also, I've had this machine for 4years now and I've never had a problem like this one.

Any help greatly appreciated.

Kind regards,


i scanned with hijackthis and AVG's resident shield has detected the infections but doesn't allow me to do anything.

Thanks for your help. I downloaded Spybot Search and Destroy and scanned. It identified 12 infected items and two of those were Trojan horses. Malwarebytes is currently doing its thing so I'll see what happens there.
