If you are concerned that you may have badware, there are a number of “symptoms” that you can look for. Please note that many badware applications are difficult to detect and may not cause your computer to exhibit any of these symptoms.

I’m constantly bombarded with pop-ups:

Although browsing certain websites may cause you to see occasional pop-up advertisements, if you find that you are being inundated with pop-ups there is a good chance that these ads are being displayed by unwanted software that is installed on your computer. You may even start to see pop-ups when you aren’t connected to the internet, which is an even stronger indication that your computer is infected with badware.

My homepage or browser preferences have changed

Many types of badware change your browser or operating system settings in order to show advertisements or make their own websites more visible. If when you start your browser you are taken to a page you didn’t select, or your internet toolbar is no longer functioning correctly, your computer may be infected. You may also find that you no longer have control to change your settings or preferences back to their defaults.

My computer is running slowly

Many types of badware can put a significant load on your system without ever identifying itself. The resources used by these programs to show advertisements, transmit information, or track your behavior can crash or slow your computer. If you find that your computer is crashing or running slowly with increased frequency, you may have badware.
