Malware

What is malware? 

Malware is malicious software installed on your computer, smartphone and other devices without authorization. Malware typically collects information about you — the passwords you use or the websites you visit — simply by noting what you type and where you surf online. Malware may also send emails you didn’t write or spread computer viruses.

Malware is usually installed through:

• Links in phishing emails
  
• Websites that attack computers with out-of-date operating systems or antivirus software
• Links in pop-up ads
• Shareware and other downloadable software
• Deceptive security software offers or fake antivirus programs
   

Your computer may have malware if it:

• Operates slowly
• Is inundated by pop-ups
• Redirects you to URLs different from those entered
• Includes unknown toolbars and icons
• Displays unusual error messages
   

If you suspect your computer has been infected with malware, take the necessary steps to remove the unwanted software from your computer.
