Spyware
Spyware is software that is installed on your computer without your consent to monitor the way you use your computer. It can be used to display pop-up ads, send you to websites you did not mean to visit, monitor the websites you surf or record keystrokes, meaning the software could record your usernames and passwords.
Clues that spyware may have been installed on your computer are:
- Onslaught of pop-up ads
- Your browser taking you to sites you did not enter in the address box
- A change to your Internet home page that you did not make
- New toolbars
- New icons in your browser window
- Keys that don't work properly
- Random error messages
- Slow performance when opening programs or saving files
Tips to help protect your computer from spyware
- Update your operating system and Web browser software to make sure you have the latest protection.
- Only download free software from sites you know and trust.
- Don't install any software without knowing exactly what it is.
- Set your security setting to at least “medium” to avoid unauthorized downloads.
- Avoid links in pop-up windows.
- Don't click on links in spam that claim to offer anti-spyware software.
- Install a personal firewall to stop uninvited users from accessing your computer.
How to get rid of spyware
If you think your computer might have spyware on it, follow these steps:
- Get an anti-spyware program from a vendor you know and trust, choosing one that can undo changes spyware makes to your system.
- Set it to scan on a regular basis — at least once a week — and every time you start your computer, if possible.
- Delete any software programs the anti-spyware program detects that you don't want on your computer.
