either your virus scanner is crap or the client was infected with a virus that was already on your computer - Google: Computer Virus The client from our downloads section on the site is virus free. I've checked it with multiple virus scanners. Also, there is no virus during updating because I have several on-access scanners. No command or application execution gets by without my permission and I have not seen anything out of the ordinary. You're talking to a very paranoid guy. I assure you, thats not from us.
The only other reason could be is: you are telling a lie mr. someguy with only 1 post.
Welcome to the forums by the way.
