I am having the same problem as described in this post:

I downloaded the program file (for Pocket PC software) from edonkey2000 P2P program. After unzipping the file, there were two *.exe files.
I ran the file named "setup.exe". But I received a following error message:

The instruction at "0X10312ea4" referenced memory at "0x03c91000". The memory could not be "written". Click OK to terminate the program.

After this incident, I am getting a small icon with the following message:

"Invalid filename"

This message keeps popping up on my windows every one minute or so..

I ran the Norton Antivirus 2003 and Trend Micro (online virus scsn) and there was no virus detected.
I also ran Ad Aware 6.0. I removed all the spyware files. But still I am getting the "Invalid Filename" message.

I don't think it's the virus - because after reboot, everything runs fine - however, I still get annonying "Filename Invalid" message.

PS: thereīs nothing unusual on startup itens, registry included

did anyone find any solution for this?? itīs so damn annoying.
