I like Webutation a lot better than Web of Trust, which I think has too much mere gossip.
I suggest you look into anti-keylogger programs. Spy Shelter has the best premium version, but Zemana has the best free version. Those two are in a class by themselves.
Kaspersky IS is a great choice. Its AV testing puts it in the top 2 with marvelous consistency, and the most recent firewall test I've seen had Kaspersky's firewall ranked quite high.
If you keep your eyes open you should be able to get a giveaway of Lavasoft AdAware's Web Companion. In fact if you search, it's probably offered free somewhere now. But I don't use it because I'm on an old computer, and it strains my ancient processor. Looking forward to my next computer.
