Most worms begin as email attachments that infect a computer when they're opened.
The worm scans the infected computer for files, such as address books or temporary webpages, that contain email addresses. The worm uses the addresses to send infected email messages, and frequently mimics or spoofs the "From" addresses in later email messages so that those infected messages seem to be from someone you know.
Worms then spread automatically through email messages, networks, or operating system vulnerabilities, frequently overwhelming those systems before the cause is known. Worms aren't always destructive to computers, but they usually cause computer and network performance and stability problems. A trojan horse is a malicious software program that hides inside other programs.
It enters a computer hidden inside a legitimate program, such as a screen saver. Then it puts code into the operating system that enables a hacker to access the infected computer. Trojan horses do not usually spread by themselves. They are spread by viruses, worms, or downloaded software. Spyware can install on your computer without your knowledge.
Spyware can track Internet search habits and can also redirect your web browser to a different website than you intend to go to. A rogue security software program tries to make you think that your computer is infected by a virus and usually prompts you to download or buy a product that removes the virus.
The names of these products frequently contain words like Antivirus, Shield, Security, Protection, or Fixer. This makes them sound legitimate.
They frequently run right after you download them, or the next time that your computer starts. Rogue security software can prevent applications, such as Internet Explorer, from opening.
Rogue security software might also display legitimate and important Windows files as infections. Typical error messages or pop-up messages might contain the following phrases:. Do not click anything inside the dialog box. Are you sure you want to navigate from this page? Your computer is infected! They can cause data lost and file corruption and need to be treated as soon as possible. Return to System Security and download it to secure your PC. Press OK to Continue or Cancel to stay on the current page.
