"actskin4.ocx" was detected by PestPatrol

I am using avast home under win xp home sp2 of japanese lang.
It is said in Japan that PestPatrol detects "actskin4.ocx" so that avast should include spywares.
I tried to find evidences what avast has spywares, but I haven't yet.
I wanna believe it's a false positive of PestPatrol.
How do you think about it ?

Also I tried to find evidences what AntiVir and AVG have spywares, but I haven't yet.
These, AntiVir, avast and AVG, were scanned by spybot and ad-aware SE, but no spyware.

Do they include spywares inside of a freeware version ?
Is CA making traps for them ?
Or are some ani-virus vendors trying to make traps for freeware version of antiviruses ?

 

Thats a huge false positive and avast! CERTANLY and 150% sure DOESN'T contain ANY spyware whatsoever.
Also Pest Patrol tends to report all sorts of harmless stuff as spyware so i wouldn't really rely on this program alone...
