Avira Free Antivirus with anti-spyware

Know your enemy

Understanding how spyware works is the first step to protecting yourself.


Spyware is a type of malware (malicious software) that infiltrates your device and collects and shares personal information about your computer or network. 

  • Monitors your internet activity, tracks your login and password information, and spies on your sensitive information.
  • Commonly used by criminals to steal your name, address, passwords, and bank and credit card details.
  • Also a tool for unscrupulous advertisers and companies to collect and sell market data about you.


Spyware is one of the most common threats on the internet. There are four main types:

Adware: Tracks your browser history and downloads to display ads for similar products.

Trojans: Dressed as legitimate software, such as a Java or Flash Player update, to entice you to download them.

System monitors: Records just about everything you do on your computer, including keystrokes, chat-room dialogs, websites you visited, etc. System monitors are often disguised as freeware.

Tracking cookies: Tracks your web activities, including searches, history, and downloads, for marketing purposes.


Spyware runs hidden from the user so it’s often difficult to detect. Look out for the following symptoms: 

  • Slower system performance and more crashes (it consumes resources like an annoying house mate)
  • Increase in annoying behavior such as showing pop-ups and re-routinged web pages
  • Altered web pages or default search engines
