Thanks for your response. In fact, I'm already using TrueCrypt right now and so far, I'm really liking it alot.

I remember reading somewhere that backdoors are left in some commercial encryption software so that the government can easily access encrypted files, saving them man hours and computers cracking the encrypted file to recover the plain text.<br />
<br />
Is this true?<br />
<br />
Should I use an open-source software TrueCrypt (which my friend advised me to use) over the closed-source MyWinLocker that came with my recently bought Acer Aspire Timeline AS5810TZ-4274 NoteBook?<br />
<br />
And how does MyWinLocker compare to TrueCrypt in terms of features?

Encryption: open-source more secure than closed-source?

Operating system security (OS security) is the process of ensuring OS integrity, confidentiality and availability. OS security refers to specified steps or measures used to protect the OS from threats, viruses, worms, malware or remote hacker intrusions. OS security encompasses all preventive-control techniques, which safeguard any computer assets capable of being stolen, edited or deleted if OS security is compromised, including authentication, passwords and threats to systems and programs.

OS Security

Encryption is the process of encoding messages or information in such a way that only authorized parties can read it. In an encryption scheme, the intended communication information or message, referred to as plaintext, is encrypted using an encryption algorithm, generating ciphertext that can only be read if decrypted. For technical reasons, an encryption scheme usually uses a pseudo-random encryption key generated by an algorithm. An authorized recipient can easily decrypt the message with the key provided by the originator to recipients, but not to unauthorized interceptors.

Encryption

Digital forensics encompasses the recovery and investigation of material found in digital devices, often in relation to computer crime. Digital forensics investigations have a variety of applications. The most common is to support or refute a hypothesis before criminal or civil (as part of the electronic discovery process) courts. The technical aspect of an investigation is divided into several sub-branches, relating to the type of digital devices involved; computer forensics, network forensics, forensic data analysis and mobile device forensics. The typical forensic process encompasses the seizure, forensic imaging (acquisition) and analysis of digital media and the production of a report into collected evidence.
