When spyware is on your PC it will almost certainly cause your Internet connection to dramatically slow down and you will get an excessive amount of annoying pop-up windows. Left untreated, spyware could begin to crash your computer and even lead to identity theft.
Proactive anti-spyware protection is essential in keeping your data private. Programs such as Webroot Spy Sweeper and eTrust Pest Patrol are offered for a small yearly subscription fee and they will help prevent, scan for and remove the bulk of unruly spyware from your computer. Once installed, ensure that your software program is automatically downloading updates on a weekly basis and set to perform a full system scan every month.
Firewalls Are Your Friend
Information travels between computers and networks through various data ports. In addition to other security measures, firewalls implement a "stateful inspection" of these data ports, preventing unrequested (which is to say — bad) data from coming into your computer or network. In essence, firewalls hide your PC from others trying to get in through the Internet. Various software companies offer firewall protection, but hardware-based firewalls, like those frequently built into network routers provide a better level of security.
