When you’re online, Trojans or worms can be installed on your PC through a loophole in your software that you haven’t patched, through shareware you’ve downloaded, or through an e-mail attachment.
These Trojans or worms can be used to take remote control of your machine for various harmful actions as displaying ads, monitoring your browsing behavior, launching a denial-of-service attack, hosting a phishing site, or capturing your keystrokes to record information such as usernames, passwords, and credit-card details.

Theft of passwords and game resources is spreading in the virtual worlds and multiplayer online games.
Vishing, similar to phishing which executes through phone calls to your mobile number, has made an appearance, and is growing.
