How to Remove Adware and Spyware

Spyware and adware are small software apps that get installed in the user PC and do all sorts of undesired stuff. There is very thin line differentiating between spyware and adware. As name suggests a spyware is a program that can keep an eye on what the user is doing on a particular machine, like keystrokes logging, database of site he/she is visiting and other personal information. This information is then intended to be sent to third party, who can use it for marketing research or simply to steal the particulars. It’s a big security vulnerability and risk for the user.

On the other hand, typical free programs (free wares) use adware to recover or reduce the cost of application development. Adware will simply pop up advertisements at pre-programmed moment for the user to see. Advance adware can also use the Internet connection to update or download new ads. Sometimes it could be quite annoying and distracting for the user who is unknown of this. In this tutorial we have mentioned the utilities and steps that can be followed to get rid of these undesired apps.


Preventive Measures
