Strange Process 5ybb.exe

I have a weird process that keeps showing up on my WindowsXP Pro box. The process PID is 5yBB.exe I've searched my system, and I can't find it anywhere. I've searched google and it's not listed. I searched the registry and there are also no entries.

It takes up about 8MB of memory and if I leave my system running long enough more instances will eventually start running. The other night I had around 20 instances running. That's when I started to get concerned.

I'd like to find out what this process is doing and how it's started. If you have any suggestions on how I can track this sucker down let me know.




 
run hijackthis in safe mode, find it in the startup entries. Select it, hit fix, then delete the file manually.

please post your entire hijackthis log for review, that is a random file name generated by malware

Before you do anything
1. Make sure that you have extracted HiJackthis to a folder that is isolated before removing anything, for hijackthis makes backups within the folder it is in.
2. Disable system restore, malware can come back through it.
3. Reboot into safe mode.
4. Close all browsers/windows explorer.

fix the following in hijackthis(kill the process in process viewer, if its there)
