I have a veeery weird and interesting problem.
I downloaded a little piece of code, in *.txt form. It it said to be a polyglot, that is, exactly the same code would compile and work in more programming languages.
In this case, the languages are : COBOL, Pascal, Fortran, C, Postscript, sh, 8086 asm.
I downloaded it and renamed the text as "polyglot.com". Then i opened it.
A DOS window did pop up, no text on it, just some "_" were poping in the window randomly and thats it. BUT, in the exact same moment i opened "polyglot.com", my printer started to roll the paper without stopping.
I have a very old matriceal printer, Epson LX-300+. It uses rolls of paper, not A4 papers. After i opened the program, the paper started to roll, like it was printing, but nothing was written on the paper. It was just moving the paper, over and over.
I stopped the program imediately with Task Manager and deleted it from the desktop.
I stopped the printer, but when i opened it again, it was still rolling the paper without printing anything.
I restarted the computer, with the printer closed, everything was fine, but when i started the printer, damn, it was rolling the paper again.
I restarted in safe mode. The printer was fine...
This is the link to the nasty program. : http://www.nyx.net/~gthompso/poly/polyglot.htm
Search for "polyglot.txt", authors: Kevin Bungard, Peter Lisle and Chris Tham.
The text file seems to be innocent, it is not a virus or spyware. I have Avira Free installed on my system and updated everyday and i also scanned the file, (renamed as .com) with Nod32.
In source code form, it is even more innocent. A lot of commented lines and 2-3 lines of code.
I don't understand how this program acts as a COM application, that's the problem.
And WHY, does this program affect my printer driver, even AFTER i reboot?
I checked the startup with msconfig, but nothing new was added
Can anyone suggest a solution, or an explanation?
(My system is mb: Kobian KOB KT133a FSX, cpu: AMD Athlon, 1000 MHz, mem: 512 MB (PC133 SDRAM), vc: NVIDIA Vanta, os: Xp Professional SP2 with all the updates and security patches.)
Thank you very much.
