Example: Kaspersky Anto-virus says there is a worm in CK3: PDM.Worm.P2P.generic Process (P.I.D. 66068) <--- This is a false positive, we have submitted Chess King 2 and Chess King 3 to all major virus protector companies and they have whitelisted our program in new virus definitions, so you should not get this warning if you have fresh virus definitions in your virus protector program. If you still get a warning from your virus program, first be assured there is no virus or worm in Chess King, we guarantee it, and please send us a copy of the warning so we can write and have Chess King whitelisted everywhere.
