PC Tools Firewall Plus Free Edition

"Almost had to reinstall XP"
Pros? Are you f-ing kiddin'?
The firewall didn't even install properly. When reaching the last step of installation, pressing "next" made my PC go a fraction of a second into the blue screen of death and restart itself. Loaded the fail-safe defaults from Bios, booted into XP in safe mode, logged into my administrator account, tried to uninstall this firewall and BAM: blue screen of death and another self-restart. Tried to uninstall it with CCleaner in safe mode (awesome software I really love for keeping my PC clean), but again the uninstaller starts, I agree to uninstall this firewall and BAM-BAM: blue screen of death and self-restart. I had to go to Program Files and delete the installation folder and my PC seems to work alright once again.
This is an XP crasher! I hate it, it's an abomination and I can't believe crap like this invaded CNET lately. Download and use at your own risk, folks. I'm going to look for a good firewall that won't destroy my PC.
