Webroot Antivirus: The best protection against viruses, spyware data theft and hackers.

Description: Details
YesNo.862

It is a very dangerous memory resident parasitic virus. It hooks INT 10h, 16h, 21h and writes itself to the end of EXE files that are executed. Depending on the system time the virus exchanges keystrokes:
r -> t
n -> m
y <-> n
ESC <-> ENTER

As a result, a message box or some menu will receive wrong key, and data may be lost while saving them to disk, copying and so on.
