I'm Having a problem With my MS-DOS Program\~Tmpa. I rebooted my COMPUTER and several popups come up on the screen and the only optoin that is given is to ignore or cancel. There is about Five To Six Popup windows the show up every 20 to 25 min. I fact they just poped up right now the hole window states from top left.

16 bit MS-DOS SUBSYSTEM
~tmpa.exe
The NTVDM CPU has encountered an illegal instruction.
CS:0def IP:0113 OP:ff ff ff d4 d0 CHOOSE 'Close' to terminate the APPLICATION.

\Close\ \Ignore\

The windows that popup with this window have a blue bar at the top and are label ~tmpa.exe they are showen with black backgrounds and suply no data at all. Again this happens every 20 to 25 mins and will continue to show up. If I leave the preveus windows there every 20 to 25 mins it will build up with more windows of the same.Your system is infected with malware...if you google ~tmpa.exe
there are LOTS of talk about it and how to remove the malware.
