Possible Malware problem

My computer has been intermittantly slow and unresponsive, and I've gotten a blue screen once this week (but alas not quick enough for info from that). This morning I surprisingly found some extra tool bars in all three of my browsers, which I either disabled or removed. I have no idea how they got there so I thought I'd follow the malware removal procedure, which I have. And now I want to see if someone can offer advice based on the logs that have been produced.

There is a complication. I have also had a hard drive failure warnings today indicating that I should perform a back up. The Intel Matrix Storage Console tells me " A hard drive is reporting a SMART event", and that I should refer to replacement and recovery instructions in the manual. This seems like it could be a totally different concern, but before I do anything with the hardware, I just wanted to see with the experts about the malware logs.

Thanks.
