Virus & Spyware
Many computer viruses are stopped before they can start, but there is still an ever growing concern as to what do computer viruses do and the list of common computer virus symptoms. A computer virus might corrupt or delete data on your computer, use your email program to spread itself to other computers, or even erase everything on your hard disk.
Viruses can be disguised as attachments of funny images, greeting cards, or audio and video files.
Computer viruses are often spread by attachments in email messages or instant messaging messages. That is why it is essential that you never open email attachments unless you know who it's from and you are expecting it.
Spy & Malwares?
Spyware is a category of computer programs that attach themselves to your operating system in different ways to suck the life out of your computer's processing power. They're designed to track your Internet habits, bother you with unwanted sales offers or generate traffic for their host Web site. According to some estimates, some 80 percent of all personal computers are infected with some kind of spyware.
