Prevent Spyware Infections
Spyware is a general term describing sinister programs that sneak into your computer by tricking you into installing them or by hiding in other programs you install. The dangers of spyware are that it can do the following:
• Install a “keystroke logging” program that allows a criminal to see everything you type on your keyboard (including passwords and credit-card numbers)
• Hijack your Internet browser and change its default homepage and/or search engine; track your Internet-surfing habits
• Send your private information to hackers who can use it to commit identity theft, or to online marketers who will send you customized pop-up advertisements
How Does Spyware Infect a Computer?
There are numerous ways that spyware can sneak into your computer, including the following:
• Internet advertisements: When you click on a malicious pop-up ad, spyware can be downloaded to your computer.
• File-sharing software: It hides inside programs used for illegally sharing MP3 music files or pirated movies.When you install the software, the spyware is installed at the same time.
• Pirated software: Illegal copies of software purchased on the street or downloaded from the Internet often contain spyware.
• Shareware and freeware: It can lurk inside inexpensive or free software available on the Internet from non-reputable vendors or persons.
• Fake spyware-removal programs: Believe it or not, some antispyware programs actually install spyware.To stay safe from this scam, only install spyware-removal software that has a solid, respected reputation.
• E-mail attachments: Just like a virus, spyware can be installed on your computer when you open an infected e-mail attachment.
• Hackers: A hacker who has already found a way into your computer courtesy of a virus, worm, or Trojan horse, can install spyware on your system.
