I expected more information on viruses, spyware, adware, and malware
Example: I checked several FREE antiVirus, antispyware, antiadware and antimalware programs to see how well they performed, example try "A squared", performs better than expected for free software. Some of the old standbys are no longer tops - You may want to add a review to compare different FREEWARE and different commercial software - they also have instructions (step-by-step) on how to manually remove these pests. If all else fails, reload the system - Microsoft and other vendors have detailed instructions - and hard disk manufactures give free software (downloads) to check disk performance.
If you want some of this information to add to your site, either search the internet (I did) or look it up on my site (it's free)
