Do not open email attachments from suspicious senders. Do not open email attachments from known senders if they look suspicious. Even if you do know the sender of a suspicious attachment, it would be wise to follow up with them and ask if they intended to send the attachment as his or her mail account could have been taken over. In short, be very cautious and skeptical of any attachment you receive from unknown senders or in suspicious emails. It is also good practice to not use Windows as an administrative user. Windows keeps hidden backups of files via a technology called Volume Shadow Copy. Not running as an administrative user ensures that the ransomware cannot encrypt those backups as well. Your system administrator will know how to recover files from Volume Shadow Copy. The same applies to Mac OS X as it is just as vulnerable to these types of attacks.


If you are afflicted with Testlacrypt, do not pay the ransom. There is no guarantee that you will receive the encryption key after doing so. Your best bet is having a good recent backup to recover from.
