Virus spreads into other files by attaching itself into computer. It needs a carrier to get into computer and harms other files. Worm has an ability to copy and transmits itself into other computer by email, this will not spread into other file but harm network instead. Trojan could not spread into other file, could not transmit itself into other computer but fools a user to download it to set into computer. Since Trojan has installed, it is incontrollable. There are many kinds of Trojans.

Spyware will not spread into other file, not even transmit itself into other computer, but fools a user to download it into computer or by a gap of web browser to install and infringe a user's privacy.

Hybrid Malware/Blended Threats is Malware which includes all the ability of Virus, Worm, Trojan and Spyware together.

Phishing is a technique of making a social engineering by using email to fool user to reveal financial statement such as credit card or online bank account.

Zombie Network Many computers which become a victim of Worm, Trojan and other Malware will be used by attacker/hacker to be an address for sending spam mail, phishing, DOS or possibly to keep some illegal software inside.

Malware has an abbreviation from Malicious Software means all programs that have hostile towards to computer and network, or it could be a name to call an ill intention of program such as Virus, Worm, Trojan, Spyware, Keylogger, Hack Tool, Dialer, Phishing, Toolbar, BHO, etc.

Owing to Virus is the first Malware which occurs and knows for long so, some news or an informal article that is less emphasized will use this word "Virus" instead of "Malware" In the fact, this is incorrect. Anyhow each Malware is difference.

 

When you first startup the new Mac, the Setup Assistant will offer to transfer your files from your old computer. If both computers have FireWire, you just need a FireWire cable to connect them. If your new computer doesn’t have a FireWire port, you can use an Ethernet cable or wireless network to migrate files, as long as both computers are running Mac OS X Tiger 10.4.11 or later. See Apple support article HT3231 for instructions.

If a migrated printer setup fails to work, you may need to delete the printer in the Printer Setup Utility and recreate it.

You can also transfer files after you’ve already setup your new Mac by launching Migration Assistant (in the Utilities folder). If you plan to do this, do NOT create a new user account with the same name as any user account you plan to transfer. If you do, you’ll be forced to rename the user account you restore and it will cause little annoyances later on.

Over the Internet--since that approach gives you both a constant, background backup and physical separation.

The easiest Internet backup service I know of is Carbonite. Once you set it up, it quietly backs up your files in the background as you work. The first, full backup can take days (you didn't ask me for the fastest way to back up data, did you?), but you'll barely notice it after that. Unlimited backup (for one PC) costs just $59 a year.

Leaving your PC on permits your system to scan for viruses and to back up data while you sleep, and it lets you avoid the hassle of booting in the morning. But shutting down saves power. What's more, Windows tends to build up garbage and problems as it runs, and a fresh boot a day keeps the errors away.

You should be aware that compromises are possible. One option is to hibernate the PC, which won't get rid of the garbage but will save as much power as shutting down the PC. Alternatively, you can put the PC into sleep mode (also known as Standby), which saves some power (though not as much as hibernation does) and allows your PC to wake up very quickly.
