Sorry to hear that you're out of work! Seems to be the big story these days, I hope it's short lived. However, you've found a great temporary solution, especially if you're going to be working on virus and malware removal because that's about the only thing more rampant than job loss at the moment.
A couple of really useful tools that you can use on a consistent basis, in conjunction with checking this forum and others like it for suggestions, would be:Malwarebytes Anti-MalwareSuper Anti-Spyware
Beyond using those, I would advise you to look at the Spyware Removal
page and read threads in the Am I Infected?
forum to get help from the experts until you're more familiar with the advanced solutions. Also, there is a discussion forum for different applications and such if you click here
that will give you some pointers.
Best of luck!
