Firewall..: I just got cable - we live in a rural area... and I networked through a router with a built in fiewall (but its not that great). Zonealarm doesnt work (unless you pay) with networks.
The software that I think/hope killed it is found here
http://www.prevx.com/
it is a 60 day free trial.There may be others that kill it. AVG doesn't.
Just deleting this file:
\sngpt\sng pokertools\unins000.exe
I'm not sure will work - the bloody thing will just respawn. BUT if you have the above file then do something about it....
