I think you shud block the pop-ups in ur IE but this will not solve the problem completely as it may not block all the pop-ups.And yes pop-ups
can also make u install spywares accidentally so u need some gud antispyware along with blocking the pop-ups.I have 1 good application installed on my system
Advanced System Optimizer,It has a tool named System protector that blocks the spyware b4 it can enter your system and will also clean the infections if any.
it also have other Privacy Protection tool.For me it is the best antispyware.Try this
it is available at cnet.
