Hi luvabeard,
I recently encountered the same problem and sent Stars an email, this is their response.

Thank you for your email.
First, I would like to assure you that the PokerStars software is completely virus and adware free. We continually run virus and adware checks on our software and servers to ensure that the software stays clean. So we do not know why Kaspersky is classifying our software as dangerous.
However, please check the settings of Kaspersky to ensure that our software is not blocked any longer.
To configure Kaspersky Internet Security suite please visit the software support page below for more detailed instructions:

Here's the list of programs that you need to add to the firewall's safe zone:
PokerStars GUI (or .exe)
PokerStarsUpdate.exe
PokerStarsCommunicate.exe
PokerstarsBr.exe
Tracer.exe
xc.exe
If you have any further questions, please do not hesitate to contact us again.
Regards
Andre
