Once you are connected to the internet it is important that you protect your personal data by avoiding spyware infections. Luckily there are some easy ways in which this can be achieved simply and without breaking the bank.
Firstly a firewall is one of the best line of defense against unwanted software finding its way on to your PC; there are a number of good ones available for free download on the worldwide web. They work by monitoring the flow of information over your internet connection, allowing only the traffic you specify from your PC and not some data transmitted by spyware, that may have installed itself onto your system. Indeed if you start with a clean computer the firewall shouldn't allow any spyware to find its way into your PC.
Secondly hackers and software writers of malware, adware and spyware have primarily targeted the users of internet explorer as this is the most common browser. Switching to a more secure alternative like Firefox, is a prudent decision.
Most spyware is installed without your knowledge, through file-sharing programs like Kazaa, and through some (but not all) Web sites that prompt you to install special software in order to view the page, or through e-mail messages that lure you with tempting links. Be aware of such prompts to download new plugins when viewing websites. If in doubt do a quick internet search of that which is trying to install.
Some browsers offer a specific option to limit pop-up windows, it is wise you use this option. Be aware of the security settings of your browser, only allow cookies for the website you are visiting.
Should you find yourself with a symptoms of a spyware infection, a legitimate removal tool can go a long way to cleaning up the effected computer. There are some good basic free tools that protect your system from most malware, you'll want to periodically run a combination of anti spyware programs. I recommend running Ad Aware and Spybot; one program can miss something that the other will detect. Note that these don't need to run on startup; just run scans with them periodically to make sure your system is safe, it is also recommended that you update each software package before use, by doing so the latest spyware threats are looked for.
Avoiding spyware and protecting your personal data is mainly being aware of what you are doing online and following a few simple safe practices.
