this is spyware that is damn hard to handle, so get cwshredder (if you don't know what this is click here->
http://en.wikipedia.org/wiki/CoolWebSearch) ,if you get it you get owned by a zillion ads and it sucks, so just in case you are pissed at ads.
CWS - WTF it does: CWS itself attempts to evade by not labelling its ads, not providing an EULA, not providing any data about itself and not having a website. Other attempts to access websites are redirected to pay-per-click search engines that may install more malware display ads, so be careful!
so its spyware.
