Well, I managed to get my laptop infected with a virus. It's still semi-functional, but it has that annoying virus that keeps on using up all the CPU on svchost.exe. Are there any apps that can easily be downloaded that you recommend for trying to cure this problem, or am I best off just reformatting?

SpySweeper from www.webroot.com is a very good product. They used to have a free trail version. They still offer a "free scan" download, but they might have neutered it so that it only detects. Its unclear from their website. Still, it might be worthwhile. Its a free download of a very strong detection engine, and if you can ID the virus, you can probably google for a manual fix or a tool to fix it.

Do not terminate it. I have 7 copies running on my main desktop; it's an integral part of the windows os. You very well may have a program hijacking through this functionality...but it's not that file in itself that's the problem...as you now know finding 250 infected files/registry entries. Surprised

svchost.exe runs Windows "services" and DLLs. It can be hi-jacked and killing it is not a real solution. Many of those "infections" might be as simple as cookies. Did you try the SpySweeper demo? I run the retail version, and it does a good job of sorting out the serious malware verses the other minor stuff. Not that my machine gets infected, but I have cleaned up systems for many family members and friends.

All of the freeware tools ToughSox mentioned are well known. They are usually run together since coverage is not as good as the retail products. But the price is right.

To answer your question: "Am I best off reformating?", the answer is YES. But that can cause more pain than folks suspect. Especially if you don't have clean backups to restore from.

You could also try Start/Accessories/System Tools/System Restore. It doesn't work as well as it used to since modern malware is very good at spreading and hiding. But it might be worth a try.

I don't think you would do any damage by killing the copy of svchost.exe process that is eating all the CPU as a short term work-around. It might help the machine run better while you back stuff up or continue trying to fix it.

Don't forget to backup your TFC configs and maps. Shocked

Bleh, my laptop crashed both times during the scan (through no fault of the program as far as I'm aware).

Since I have my main computer back up and running (installed new power supply woohoo), there's no data of any worth on my laptop, so I'm just going to reformat, and use that as an excuse to install Linux on it, heh.

Much thanks for the help anyways, peeps.

norton and spybot, tra.... nevermind, its not nice so so wont say it.

AVG or avast for antivirus.
Dr. Web's Cureit ( www.drwebfree.com ) for a one-hit-wonder av and malware removal, works when another AV prog cant be installed because an infection is preventing it.

sv_chost is a windows thing (Windows Generic Host Process, or some crap like that), and if there are many versions of it running, it's normal. hell, it takes 5 minutes for it to stop taking 99% of my CPU away form me.
If you want to know what sv_chost is doing, read this
http://www.computerhaven.info/svchost.htm
It'll give some info on what to do to check what it is actually managing.

I would try Trend Micro's HouseCall -

http://housecall.trendmicro.com/

I also use Avira AntiVir.. very low-profile virus scan, and it's free.. so even better.

Yea I have basically the same as most. Ad-Aware, and Spy-Bot Search and Destroy, and I use Mcafee for my V-Protection. I had the free trial of AVG but I let it expire and really dont need it with the Mcafee bundle I use. Another good program to use that i have is called End It All. Basically it does what it says it ends any no vital program running on your computer which is good to free up some CPU and memory usage.
