Unwanted pop-ups
A common way to detect spyware is the presence of random unwanted pop-ups. This is an early sign of infection. Normal browsing may produce pop-ups from time to time, usually missed by your pop-up blocker. If you get constant pop-ups with little action on your behalf, then that is a clear sign of a spyware infection.
This specific type of installed software is referred to as adware. It got its name after a combination of the words advertising and software. Even though designed to provide advertising, usually by flooding you with a large number of unwanted pop-ups, you may find yourself going in circles while dismissing the pop-ups. Trying to close the new windows will most likely trigger new pop-ups on your browser.
Slower Internet Connection Speed
Noticing that your Internet connection speed has dropped can help you detect spyware. The programs are not designed for size and efficiency and will reduce the response and bandwidth of your Internet connection. Sometimes the increased system resources usage will cause your computer to crash. Remember, if your connection is not up to specs, you may be infected.
Changes in Web Browser Settings
Common spyware functions include, the installation of new toolbars and browser components. Your browser's settings will change completely, and they will revert to the way the program sets them after a computer restart. This also applies to some toolbars that will be replaced if you remove them.
New Homepage
Another common result of infection is the homepage hi-jacking. Your browser will present a different homepage when launched, a change you have never approved, and you will not be able to undo. These new home pages usually provide revenue for the spyware creator or one of his sponsors.
These are simple ways to detect spyware. However, you will need help to detect spyware that is designed to work stealthy and hide in uncommon places (like folders your rarely use). The user will not be aware of this kind of infection, so it is recommended the use of scanners or spyware detectors.
Anti-spyware will detect and remove spyware installations and all traces, adware, malware, keyloggers and cookies, all of this serving no use but they will decrease your computer's performance and Internet connection speeds. Simply install the anti-spyware software and after a system scan, it will report detected infections.
In some cases, besides installing scanners and detectors, you may obtain good quality specific anti-spywares like spyware nukers, removers and spyware killers. Built for specific targets, they do a great job in eliminating and terminating offending programs.
