I am having the same problem as described in this post: http://www.computing.net/security/wwwboard/forum/4628.html --- 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.
