The following precautions are recommended in the fight against spyware: install Microsoft security patches, avoid downloading and using freeware; and disable ActiveX downloads in Internet Explorer. In addition, install at least one anti-spyware program, some experts actually recommend that you have two installed. For starters you can download one of the free spyware removal programs such as Spybot Search & Destroy or Ad-aware. There are also a few good anti-spyware programs on the market that proactively protect your computer (alert you before the spyware is installed). When purchasing an anti-spyware program you need to be sure it is from a reputable company as many of the anti-spyware programs available actually place spyware on your computer. They do this by offering a free scan, which places the spyware on your computer as it is scanning. Then they entice you to purchase the product to remove the spyware.

In conclusion, if you take a few precautions and install anti-spyware software on your system you should be well protected in the fight against spyware.
