I've heard of this trojan that can now spread through Skype. I use Skype regularly and also access my online banking account occasionally on my machine. Should I be worried? I also run ClamAV and a firewall. I'm on 12.04. What steps can this noob take to gain further protection?
No, no Linux system can be affected. Please see:
"Systems Affected: Windows 98, Windows 95, Windows XP, Windows 7, Windows Me, Windows Vista, Windows NT, Windows 2000"
Wine cannot affect Linux, because it is a virtual XP, meaning that the "Windows" folder (made by wine, because some Win applications need resources from there) is fake. Even if the virus does change things in the fake "Windows" folder, it does not affect Linux.
