First off I fell victim to the ZA+MS update conflict after resolving that issue, I decided to try **bleep** firewall.
I removed ZA as per the uninstall guide and installed **bleep**. Now I am getting the following message when Windows is booting:
16 bit MS-DOS Subsystem
NTVDM CPU has encountered an illegal instruction. Click "close" to shut down the application
CS: 1082:IP0266 OP:63 65 6c 74 65
This pops up just before **bleep** starts, which makes me think something is conflicting with **bleep**, but I just can't find out what it could be.
Operating System:Windows XP Home Edition
Product Name:ZoneAlarm (Free)
