I also have been getting duped with Iwin, first my Opals wouldn't update, contacted support, did what they suggested, got into a bigger mess, then the games quit loading online, then I uninstalled their games manager, via their instructions, re-installed, next thing I know I had a very blue frozen screen. My Antivirus program, isn't as quick to respond. I can't find one that will detect AND remove for free. I tried Iwin about 5 months ago, had some of the similar problems, even got two trojans as a reward, Conficker, and Downloader, and also some worm, called Lovasan. ( not sure about the spelling sorry) It just seems these games sites and others too, could be better monitored by these antivirus and antispyware programs, and that we wouldn't have to pay an an"arm & leg to use.
I'm now using Lifetime/Roiworld, Shockwave, Bigfish, Popcap, and a few others, no more Iwin, because ILOST!!!
