This Russian trojan horse appears to be a download manager called “uFast Download Manager”. Once you launch it, a message will inform you that you’ve violated the terms of this application and it has disconnected you from the Internet.
If you want to get back online, you have to send a text message (SMS) which will charge you a certain amount of money. You will get a message back, containing the verification code you will need to enter to once again get Internet access.
CA has created an utility that will generate the verification code for you, so you don’t have to pay for the text message. For more information you can search for “Win32/RansomSMS.AH” which is the name for this new trojan, or click here.
