Unknown process causing problems

Hello everyone I need help with the web browser
Mozilla Firefox.

Just so you do know, I have requested help
numerous times from Mozilla
and its community but nothing was working.

Okay so here is my problem, I was on google and I
clicked a link, thus I
got a numerous amount of pop-ups. I open task
manager and ended my
firefox.exe process. Then when I tried to restart it I
got this error message,
" This application is currently in use by another
program." So I just figured I
had to wait a little while, I re-booted my PC and then
when I tried opening
Firefox I got the same error.

So after about a week of trying to figure it out, I
finally found the process
that is causing Firefox to not work. The process is
"mmplayer.exe" (No, not
wmplayer.exe) so I end mmplayer.exe and then I try
starting Firefox and a
command prompt window comes up, and then this
message pops up,

16 bit MS-DOS Subsystem
" C:\Documents and Setting\All
Users\Desktop\Mozilla Firefox.lnk
The NTVDM CPU has encountered an illegal
instruction. CS:05eb IP:f9a0
OP:fe ff 1e 09 a0 Choose 'Close' to terminate this
application. "

Then I have the option to Ignore or Close that
application.

I do not know what to do, also when I restart my
computer the
mmplayer.exe process will be running again. I don't
know what it is or how
to get rid of it.

The version of Firefox is 3.5.2 and I am on Windows
XP SP3.

NOTE: I have uninstalled and reinstalled Firefox
many many times and it
doesn't work. I have used the program unlocker to
find the process that is
running Firefox, and it is mmplayer.exe. Please help.

mmplayer.exe should be found by using find files.

Be sure to look at event viewer just in case other issues.

See also msconfig to look at startup stuff.

See also systernals for more detailed tools to diag.

Since this is the first problem I have heard of like this I kind of suspect an issue with your system. Any number of issues could cause this. Might even boil down to a full reload of the OS.

I know there is a switch to make portable firefox run multiple instances so I suspect it would work on normal install if all else fails.
