Gus, I suppose I don't really know the differences between virus, trojan, adware, malware, worms, rootkits or spyware. I do know my McAfee stops and eliminates some of them, my SBC Yahoo online protection finds more, AdAware finds a few more, Malwarebytes finds even more and now MS Security Essentials found about six (including that ALUREON mess) that they all had missed for I don't know how long. Since I ran the MS SE two days ago the computer and internet is faster.

I will have to see what Chrome is. I have and tried Firefox but was disappointed with it.
