I think you shud block the pop-ups in ur IE but this also 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 Protector , it not only blocks the spyware b4 it can enter your system,and will also clean the infections if any and it gives routine updates of the latest definitions and is very easy to use..
The On Execution Scanner & Alert Shields make it more efficient in the case of internet access.
For me the Advanced System Protector is the Best Antispyware...U can also give a try...
