You might look at several things.
Your browser, are you using the built in Internet Explorer? If so get Chrome or Firefox and install Adblock Plus.
hold down the windows logo key and press the R key in the open box type in, msconfig then click on OK.
Click on the startup tab and see how much junk you are running. Uncheck all the boxes except the one that loads your antivirus. It won't remove these programs but it will stop them from loading on startup.
The reboot. See if that makes a difference.
