There was a question of 'Cezar' about an assumed virus (COMMAND.COM
increased in size, message 'P-CK (1M), etc.). Jeroen W. Pluimers and
Jeroen Smulders ask some questions to get more information about the
problem.

My opinion: P-CK has nothing (?) to do with a virus, it is the
announcement of a parity-check error of the memory on the PC mainboard
( or memory card).  The system will not boot (i.e. 'hangs') if parity
errors occur in the RAM- banks. You should boot your system from a
known-good floppy and run a good memory test program. If your system
appears sick, you will have to fix it before you can go for the
virus-bust (if present at all ...)

Good luck!
