One_Half is a dangerous virus. It slowly encrypts any hard drive that it infects. The encrypted portion of the drive is available to the user as long as the virus remains in memory. When about half the drive has been encrypted, the virus displays the message:
Dis is one half.
Press any key to continue...
Once the virus is removed, the encrypted data is lost unless the antivirus program is capable of un-encrypting it.
