Need Free HIPS

Just bought my new notebook. I am looking for a free intrusion detection software( HIPS) for my new PC. I tried winpatrol but it does not seem so effective, mainly I think only monitors new srtart up and active processes. Also used Prevx R1, I like it but I think it makes my PC slow. I have used ZA Pro for a while and really liked it but I want some free one.

I have choosen already these appliances in addition,

Antivir
MS Antspyware
ZA firewall free

In addition to these utulities, I use following on-demand scanners.

Spybot
Ad-aware
SpywareDoctor( old trial version)
Yahoo antispy( small and cute, how effective I don,t know but it is really fast scanner and takes out cookies and some bigger files)


Online scans --- TM online spware scan( really fast and nice, even removes spyware free of cost)
Webroot Spuaudit

Using Toshiba satellite M 70, 1.73, 512, 40, xp home

 

have u tried antihook or system safety monitor?
