Just an FYI for everybody playing WoW, since I think most people use Curse Client for their WoW addons. Apparently one of the ads on Curse client infected not 1 but 2 of my computers, also Templar was infected by the same virus. Please do not treat this as I did when Templar told me about it and kinda blew it off because I didn't think Curse client was infected, they are. This one is kinda scary as it requires NO user input to download and install the virus. Simply by having curse client you are leaving yourself open to this virus which I believe includes a root kit virus as well. It's the most nasty virus I've ever seen and was quite a chore to remove. It's a rogue virus as well which means it will automatically change it's name and location to avoid detection and removal.
I have tried letting the folks over at Curse know about this virus but they seem to want to push it under the rug and it appears they have no intention at this time of finding its source and removing it.
I HIGHLY RECOMMEND YOU UNINSTALL CURSE CLIENT AS SOON AS POSSIBLE.
I'm just one of lots of people who have tried telling Curse that one of their ads is infected. You can visit their forums if you wish to research this further. The scariest part was my laptop which has only WoW and Curse client installed was infected with the virus this morning without even touching it. I will be adding a guild message of the day to help spread the word to other guildies.
The virus will act like a piece of anti-virus software titled "Win 7 Security 2012", it will also hijack your browser (all browsers) and redirect to infected websites. Also, it will take over the Windows scripting program and make any program you open instead just open the virus and the fake anti-virus program.
If you have been infected you will want to go to the following site and follow their directions explicitly. In fact, I'd recommend everybody that has curse client go here and follow directions for removal.
