Sometimes a problem with Firefox may be a result of malware installed on your computer, that you may not be aware of. This article describes what common symptoms are and how to prevent malware from being installed and get rid of them.

Hvordan forhindre jeg at malware bliver installeret?
There are simple rules to follow in order to prevent malware from being installed on your computer:
- Keep your operating system and other software updated: Installation of malicious software usually takes advantage of known security vulnerabilities in other programs, which may have been patched in later versions. Make sure you are using the latest version of each piece of software you use, including plugins using Mozilla's plugincheck website and Windows using the Windows Update feature.
- Don't install untrusted software: Some websites offer you software to accelerate your browser, to help you search the Web, to add toolbars that make things Firefox already does. Some unwanted programs also come bundled in software packages. Usually, these programs gather information on your browsing behavior that serve only people who designed them and interfere with Firefox. Make sure you install add-ons from Mozilla's add-on website and you uncheck unwanted programs in software wizards.
- Don't click inside misleading pop-up windows: Many malicious websites try to install malware on your system by making images look like pop-up windows, or displaying an animation of the website scanning your computer. For more information on detecting a misleading pop-up, see Pop op-blokering, indstillinger, undtagelser og fejlfinding.
- Don't run a fake Firefox: Download Firefox from mozilla.org/firefox.Note: Please report misuse of the Firefox trademark in websites using the Mozilla's Violating Website Report page and in emails by forwarding them to Mozilla's abuse email.
- Run anti-virus and anti-spyware real-time protection and scan your system periodically. Make sure your anti-virus and anti-spyware real-time protection is enabled. Scan your computer at least every month.
Hvordan slipper jeg af med malware?
The Apple Support article Harden your Mac against malware attacks has information and recommendations for Mac users. The Wikipedia article Linux malware has information and recommendations for Linux users. If your anti-virus and anti-spyware software hasn't detected malware, scan your system with the free malware scanning programs listed below. You should scan with all programs because each program detects different malware and make sure that you update each program to get the latest version of their databases before doing a scan.
