Hello - My home PC boots up and runs very slowly. I noticed that the CPU usage pegs at or near 100% usage almost constantly with a process "rundll.exe" taking up 95-100% of the CPU usage. This begins at start-up.

I've run all virus and spyware scans. I used BleepingComputer to help me eliminate the Vundo malware (thanks BC, it worked great). Have run Adaware, Spybot, Stinger, Norton AV, AVG, Avast, you name it.

What could be causing this rundll.exe to dominate the processor? Thanks for your help.

Use Spybot or msconfig to look at your startup programs and eliminate any that aren't necessary but be very careful not to disable firewall, av or antimalware programs as well as explore.exe.

Dear Enthusiast - THANKS MUCH! Although I understand business software app's., I'm a real neophyte on topics at the OS level and below. Using Spybot's advanced capabilities, I found a bunch of things in startup that (I believe) were causing the problem. Since rebooting, my CPU usage stays in the 1-2% range (since I only have IE and Outlook open). MUCH FASTER.

Follow-up: I've been getting the WinFixer pop-ups from that piece of malware, I believe is called Vundo. I used BC's solution to get rid of it, and it appears to have worked.

However, I noticed that there was a WinFixer program in the startup. Obviously, I disabled it, but though the Vundofix would've taken care of that. Put another way, I fear that I still have WinFixer remnants.

Any thoughts?

Hi, I'm a great supporter of AČ, which is a Trojan finder, but has helped me greatly in the past with obscure pests. Free to download, slow but thorough scan.
