Originally the suspect file that showed up as running on startup was "Mirka4". However, a new file named "Mirka4a" has appeared in its place, after an attempt to fix it with Hijackthis. Unfortunately I no longer have the exact dll files that showed up as BHO's on Hijackthis, but I have included one sample of each of the random sys and dll files that my SYSTEM folder was filling up with as a result of this program (I'm 99% certain these sys and dll files are associated with Mirka4a, but I guess there's a chance they may not be).

Hmmm....I cannot upload Mirka4a because it has a ".exe" extension. I tried to rename it, but that did not work. Well, here are those sys and dll files anyway.

Ok, 2nd try: I forgot to put them in a new file and compress. Sorry about that. I am now uploading the files in Mirka4a.zip

Hi DB33,

Your zip file was corrupt. Would you try again please? Create a new Folder. Move the uncompressed files into that folder.

Then right click on th folder containing the files and choose send to>Compressed.

This will compress the folder and the files inside.

Thanks in Advance,
Mo
