Dangerous new virus called CryptoLocker
There is a dangerous virus that is affecting many small to mid-sized networks. The virus comes in through users clicking on email links and attachments. The virus searches out and encrypts key data files on the local computer and accessible network shares. While the virus can be removed there is currently no known method of decrypting your files, other than paying the ransom. In the strongest possible terms we recommend not paying the ransom; a better solution is to clean the virus and restore the data from backups. While we have taken steps to further tighten filtration of email against these threats, no filtration service is perfect.
