hp deskjet driver false positive?

the fresh install of xp sp3, comodo, hp driver reported the following problem:
Backdoor.Win32.PcClient.~a@88561940 in h:\program files\HP\digital imaging\bin\hpslpsvc32.dll

all these softwares are up to date right now, so windows update, comodo update and hp software updates are all completed (and almost nothing else installed - but firefox)
I think it is reported after comodo update, but I’m not really sure
Comodo version: 3.14.129887.586, virus database 3773
the printer is hp deskjet F4500 series

the suspicious dll is sent to you by “submit suspicious files” of CIF Misc window.

Can you please investigate …
Thanks
