Great support on removing spyware from a system can be found <a href=”http://www.spywareinfoforum.com/”>here</a>.
I would definitely start with <a href=”http://www.safer-networking.org/en/index.html”>Spybot Search & Destroy</a>. You should also be running a strong anti-virus program on your computer. It is likely you may be infected with trojans or other malware also if you are having lots of pop-ups. Do a Google search for “online antivirus scan”. Check this <a href=”http://housecall.trendmicro.com/”>one</a> out as a start.
Spyware programs could be effectively eliminated using a latest and updated antispyware software like AdAware SE Pro. You should perform a full system scan to effectively remove all hiding spyware programs installed in your computer.
