What viruses does zwinky have

Well, Zwinky doesn't have a virus at all, the problem is with MyWeb Searchbar, which comes with the program.
This searchbar's classified as a malware (it contains spyware and also adware), Because of being a spyware, tracks your browsing habits, showing you ads about things you like.
IAC (InterActiveCorp Search & Media) is trying to make Zwinky & related websites look legitimate. They even paid McAfee to keep them as green website (it was yellow before).
Also, if you search by "zwinky.com" on Web of Trust it has a poor reputation.
Zwinky can be *really* dangerous for your machine, so uninstall immediately because your computer can slow down and crash, or sometimes worse: your PC can never work again. It's like Zango, it consumes the processing power and internet bandwidth, slowing down your PC.
