What are the chances that I got infected by Saddos Ads/pop ups?

[CGM]

One setting I always change on my Internet Explorer is to make sure that Enable third party browser extensions is deselected in Internet Options. This prevents certain types of malicious software from putting its hooks into your browser. I've never had a problem by doing this, but You can always change it back if it does mess up something that is necessary.
