This family of virus takes information found in the infected PC and presents it to the user as a serious violation of privacy. The user is then blackmailed into paying $300 or all private information will be destroyed or disclosed. As Kaspersky notes, actual payment should not be rendered as AV companies work to decrypt any encrypted files and one can never trust that the persons behind these malicious attacks will honor any payments.

QUOTE
Some of our non-Russian users told us their documents, photos, archive files etc had turned into a bunch of junk data, and a file called read_me.txt had appeared on their systems. Sadly, the contents of this file were all too familiar: But in the meantime, we'd just like to remind you – if you've fallen victim to Gpcode or any other type of ransomware, you should never pay up under any circumstances. Always contact your antivirus provider and make sure you back up your data on a regular basis.
