BitDefender researchers are warning of a new Trojan that scrambles victims' data, then offers a free trial of what turns out to be malicious software.

"For the most part, Trojan.Crypt.VB.U and its variants behave much like any other ransom scam," writes PCWorld's John E. Dunn. "Once loaded on a Windows system it scrambles any data files it finds before offering to unlock them for a fee, this time by sending them to a web page demanding a rather steep $69 (£44)."

"The malware's real innovation is its attempt to overcome reluctant victims' willingness to pay the fee by offering to decrypt three files in advance of them buying a full license," Dunn writes.
