Hey there everyone, I've been having a big problem with my new laptop that I bought a few months ago. For the first few weeks I had it it ran no problem. Then it started running brutally slow. To the point I couldn't do something as simple as check email without it taking all day. Anyways, long story short, no hardware faults were found by either the retailer or manufacturer. Virus scans turned up nothing. A system reformat also failed to help. Lately it's been better but still almost unusable because of the slow performance.
Anyways, I've been led to believe that it's some sort of malious virus that an ordinary scan wouldn't pick up, and would even linger after a reformat. I'm not sure, I'm not too knowledgable in such things.
Any help as to how to fix this would be greatly appreiciated. Thanks!

Can you check whether any particular process or file is using more CPU or Memory Usage in the Task Manager?
Press CTRL+SHIFT+ESC to start Windows Task Manager. On the Processes tab, click CPU and you can scroll down to find which process is utilizing the CPU. On the same Processes tab, click Mem Usage and scroll down to find which process is utilizing more memory. Let us know the results.

Well, I tried what you suggested but when I try to run the RootRepeal from the desktop I get an error message like this one.
Then the same thing happens whether or not I press Yes or No, I get this message.
Then of course nothing loads up and the program doesn't work. Any suggestions?

I looked into the Task Manager and found tha Firefox was said to be using between 18 and 50 of the CPU only when 2 browser windows were active. One being this page, the other being a simple low res YouTube video. When I looked into the Performance Tab I saw that the CPU useage would flucuate up and down quite rapidly between 50% and 97%. Again, only the previously mentioned browser windows were active along with the Task Manager. Nothing taxing on the task bar either.
Going back to what you asked about the Processes Tab, it's Firefox again with explorer.exe behind it using about 5. The memory indicates the same kind of useage.
Not sure if these stats are normal but I know that if I try to load up Facebook or someother program the CPU peaks out to 99% if not 100% and everything slows to a craw and causes video and music to become all staggered and jumpy. Extremely annoying.
Any suggestions would be welcome. Thanks!

Try running ChkDisk to see if there is any harddrive problem and then do a disk defragmentation on your computer. Here are the links to Microsoft Articles with detailed instructions. (Both links are for Windows XP, I think it is similar in Windows Vista also).
If possible, try to remove the windows temporary files before you run the chkdisk scan:
1. Click the Start button and then click All Programs > Accessories > Run.
2. Type %temp% and click OK.
3. In the windows temporary folder, select all files/folders and press Delete.
4. Click Yes to confirm.
After that, check whether the problem(computer slow) still persists.

If necessary, go into safe mode in order to provide the Rootrepeal and GMER logs. Some rootkits are able to survive reformatting, depending on the procedure used. The links are in Dbrisendine's post. Please post the logs using the attachment link below the post button.
