Unfortunately, you've infected yourself with aggressive
spyware that you can't simply remove by uninstalling it. The longer you wait with this type of spyware, the more it will infect your computer with different programs and trash that you really don't need. Please don't take any other words of advice (other than my suggestion below) from this forum or any other besides the one I'm linking to below.
suggest going onto http://www.bleepingcomputer.com/
, making an account the the forums, and posting in the "Am I infected? What do I do?" section. In that forum they will help you run scans, ask for logs, etc... When they decide that your issue is no longer relevant for that forum, they will urge you to make a new thread in a different forum (they'll tell you which one) that corresponds to the problem.
Don't wait, act upon this spyware today. Make sure that through the process of talking to the people on bleepingcomputer.com that you don't make any global changes to your computer as this could render all of the logs, work and conversation you had useless to the experts at bleepingcomputer.com and require you to go through the whole process again. Also remember that when dealing with the experts on this subject, you must be patient.
Often times it takes a few days for your first post to be responded to, but be assured it will
be acknowledged. In this time period you have to be careful of what you download and change to your computer.
Good luck and safe surfing.
