I downloaded version 9.0 today and restarted my PC. When I made the first mouse click in a text box I got the BSOD (blue screen of death) referring to file - icsak.sys not being verified. I traced this to the Check Point directory and then deleted Zone Alarm. The problem went away.
I then re-installed and was back to same position. I checked on web on my other PC and there seemed to be some doubt as to the status of this file. It could have been a virus. after further searching, I renamed the file and turned off Force Field.
Is there a better solution to this?
