Security should be a very important and concerning issue in you every day activity. No matter you are part of a company or a home user, it is very important to protect your files. Computer Security does that for you encrypting sensitive data, hiding it in innocent carriers, allowing safe transfer through encrypted self-extract package, deleting files beyond recovery and locking application from your children or "welcomed quests".
Encryption is done using one of over 20 algorithms like Twofish, Cast128, Blowfish or Shaphire II. A special algorithm is used for secure erase that overwrites every bit of information with a random number of layers of data.
