Be carefull. These sites are actually the main reasion of the problems.
These sites actually fraud advertisement sites. Their main purpose is to first install their spywares or adwares on users system.
These spywares or adwares are installed with many freeware software, pirated softwares or while we are surfing onto those types of sites without a proper internet security software installed.
if you visit on these types of sites they will convince you to purchase their software to remove these spywares.
so be carefull and install best antivirus and spywares as posted by dhanusaud:
