I'm experiencing this one more recently. An example of this (which happened now). This doesn't come at the start or end of a program. But, while I'm working on it. I was just watching a video, when this one popped out suddenly. I accidentally pressed the "OK" button (which caused my dial-up to get disconnected). But, thats not important now.
Another example, I got the same error while saving a game (with the game's executive file). And so, I have to terminate it. If it isn't an error, well - then, Is it a VIRUS?
"Sadly, My antivirus doesn't detect any..." And, this has been a serious problem for me (as its appearing frequently). I get this one on some unlucky days. But, not every time I run the program.
Well, I thought the issue will be as Josh answered. I have a thought that it is actually a virus. Now, it has wide-spread over my computer. When I click several EXE's it must say
Application. But, it indicates them as
"%1" %*. Most of my exe files return the same error-message if I try to access them. And, a process named
ntvdm.exe runs every time with the help of another process named
F.exe. When I end the process, it loops again. I think, all these are related issues. The problem is, my AVG now detects itself as a virus. So, I uninstalled it in order to prevent it from deleting files.
What do I do now? (other than formatting?)
