DNA Super Computer.

One gram of your DNA can store 716,800 Gigabytes of data. The total mass of DNA in your body is about 250 grams. This means, your whole DNA can store 179,200,000 Gigabytes of information. On the other hand, your brain can store approximately 2,621,440 Gigabytes of data.

Combining the storage capacity of both your DNA and your brain, the total would be 181,821,440 Gigabytes.

Although I also included the mass of DNA that makes up your brain cells, the subtraction wouldn’t change much in the final result. To sum it up, your body can store approximately 181,821,440 Gigabytes of information.

Titan, which is the world’s most powerful supercomputer, can store 41,943,200 Gigabytes. That’s only 23% of your body’s storage capacity.

Your body has a storage capacity that is more powerful than 4 supercomputers combined.

Difference between Viruses, Trojans, Worms and Malware.

I. Malware
The word Malware is short for malicious software, and is a general term used to describe all of the viruses, worms,spyware, and pretty much anything that is specifically designed to cause harm to your PC or steal your information.

II. Viruses - Wreak Havoc On Your Files
The term computer virus is often used interchangeably with malware, though the two don’t actually have the same meaning. In the strictest sense, a virus is a program that copies itself and infects a PC, spreading from one file to another, and then from one PC to another when the files are copied or shared.
Most viruses attach themselves to executable files, but some can target a master boot record, auto-run scripts, MS Office macros, or even in some cases, arbitrary files. Many of these viruses, like CIH, are designed to render your PC completely inoperable, while others simply delete or corrupt your files the general point is that a virus is designed to cause havoc and break stuff.
You can protect yourself from viruses by making certain your antivirus application is always updated with the latest definitions and avoiding suspicious looking files coming through email or otherwise. Pay special attention to the file-name—if the file is supposed to be an mp3, and the name ends in .mp3.exe, you’re dealing with a virus.

III. Spyware - Steals Your Information Spyware is any software installed on your PC that collects your information without your knowledge, and sends that information back to the creator so they can use your personal information in some nefarious way. This could include key-logging to learn your passwords, watching your searching habits, changing out your browser home and search pages, adding obnoxious browser tool-bars, or just stealing your passwords and credit card numbers.
Since spyware is primarily meant to make money at your expense, it doesn't usually kill your PC—in fact, many people have spyware running without even realizing it, but generally those that have one spyware application installed also have a dozen more. Once you've got that many pieces of software spying on you, your PC is going to become slow.
What many people don’t realize about spyware is that not every antivirus software is designed to catch spyware. You should check with the vendor to make sure the application you are using to protect you from malware is actually checking for spyware as well. If you come across a PC that is already heavily infected, run a combination of Malware Bytes and Super Anti Spyware to clean it thoroughly.

IV. Trojan Horses - Install a Backdoor Trojan horses are applications that look like they are doing something innocuous, but secretly have malicious code that does something else. In many cases, Trojans will create a backdoor that allows your PC to be remotely controlled, either directly or as part of a botnet—a network of computers also infected with a Trojan or other malicious software. The major difference between a virus and a Trojan is that Trojans don’t replicate themselves—they must be installed by an unwitting user.
Once your PC has been infected with the Trojan, it can be used for any number of nefarious purposes, like a denial of service (DoS) attack against a web site, a proxy server for concealing attacks, or even worse—for sending out buckets of spam. Protection against Trojans works the same way as viruses make sure that your antivirus application is up to date, don’t open suspicious attachments, and think long and hard before you try and use a downloaded crack for Photoshop—that’s one of malware authors’ favorite spots to hide a Trojan.

V. Worms - Infect Through the Network Computer worms use the network to send copies of themselves to other PCs, usually utilizing a security hole to travel from one host to the next, often automatically without user intervention. Because they can spread so rapidly across a network, infecting every PC in their path, they tend to be the most well-known type of malware, although many users still mistakenly refer to them as viruses.
Because worms often exploit a network vulnerability, they are the one type of malware that can be partially prevented by making sure your firewall is enabled and locked down.
