almost any computer guy will tell you to use spybot search and destroy/hijack this/avg free antivirus to maintain the security of you machine. I have been using these tools for years without a single issue on my machines, and hijack this will digg you out of a hole for sure! Oh, I too hold a Bachelors in Information Systems, and have found firefox ran in a native unix environment to be, if anything, a hassle for the average user. IE is/was/will be the end all of browsers. Google Chrome was looking good for a while, but I think it got held up.
