Is this false positive? (CHKRZM.EX_/chkrzm.ex Win32:Malware-gen) Win XP SP3!

So avast found this from my computer (did a clean install of XP today and it still finds it)

CHKRZM.EX_/chkrzm.ex Win32:Malware-gen

i have Windows Xp SP3 and avast is the only av to detect this file. I have scanned it with virscan.org, kaspersky virus removal tool, avira and few others and no detection on anything else, but avast…

Avast only detects the file if i scan i386 folder myself

Upload as a false positive from the chest, it appears to be a part of the windows chess game
