Try running a scan on malwarebytes with the window open.
If that doesn't work try doing an online scan in IE at http://www.eset.com/onlinescan
. Tick remove found objects, and remove unwanted applications.
Try using RogueRemoverFree which is from the same people that made Malwarebytes Anti-Malware, which can be found at http://www.malwarebytes.org/rogueremover.php
Might i also suggest trying out another product... I use Spyware Terminator as my main product, which provides free real-time protection as well this can be found at spywareterminator.com and integrate ClamAV from within the settings.
Apart from that im not allowed to really help you, and this thread should be removed to the am i infected? what can i do? forum.
Try my suggestions, but if they don't work then seek professional help from our HijackThis team.
