Sometimes, nasty little things get onto our computers. These little nasties are called "spyware/adware/malware" and are usually a real nuisance to get rid of once they've found a home on our PC. They might cause ads to pop-up, or worse yet, they might collect our keystrokes and send them back to some bad people for bad intentions.
We recommend you install a software like AdAware (http://www.lavasoft.de/) or SpySweeper (http://www.webroot.com/En_US/consumer-p ... eeper.html) and use it at least weekly.
These softwares prevent these unwanted "squatters" from finding (or at least "keeping") a home on your PC, and thus, they keep your computing experience safer.
