SpywareBlaster's "immunizer" is similar to Spybot SD's Immunizers. It prevents spyware from being installed, or actually the sites that lead to spyware and malware. I appreciated this software's system "snapshot", something just like system restore but on a diet version. The updates in small, simple files is also great.
I would like a daily interval of updates, well at least one a week, since SpywareBlaster takes an awfully dreaddul 3-4 weeks to update once. I would also suggest upgrading V.3.5.1.
