You may not know it, but at this moment your computer is most likely being crawled by Internet bots. What are these software applications doing? They are scanning your machine, dropping snippets of code on to it and watching your surfing habits. Generally these bots are sending information back to numerous companies in an effort to market to you more efficiently. The good news is you can fight back against the bots by installing a couple of free programs that will remove their malware.
I have been running both programs on my machines because they seem to work differently and catch unique items. Note: These programs are not virus protection software; they are programs designed to only remove bots from your machine.
Spybot Search and Destroy
Did you find a bunch of bots after you ran the software?
