The
msdos.exe is not a valid MS Windows file. The ONLY files with that similar name that do exist on the system are;
1.) msdos.sys
optionally may exist
1.) msdos.inf
2.) msdosdrv.txt
So your safe deleting it, as long as it was named MSDOS.exe. More than likely it was a file from the virus/trojan creator to appear as a valid msdos file.
If the files were not detected from F-Prot, then it is possible you did not download the updated signature and definiton file? If you did also download those updated files, then you may wish you send a report to the creators of f-prot so they can examine and include those files into the next def file release.
I am not aware of the current abilites of any A/V program, as I am not in a habbit of even running a/v apps. I can honestly say in a 10 year span of messing with computer, and not running anti-virus apps, I have only been infect 4 times. And I've been using computers for a much longer time than that.
Maybe you can try the additional DOS program mentioned - Bit-Defender, they also do offer a windows version also.
