If you are wondering where infections like System Check come from, they are coming through Flash ads on many sites. I got system check through a flash ad just today, and had a terrible time getting rid of it. There should be a law banning flash-based adverts. The ad that inserted system check came from radio.com. So any website you go to could insert malware through flash based ads. Radio.com almost certainly has no idea that some of the flash ads being served are inserting malware.

I call upon Congress to enact a law making flash-based advertising illegal. That is the only way to stop infections like system-check.

Such a law were to pass by Congress, it would only deal with U.S. based web sites. Vistors going to sites based in other countries would not be protected.

In April 2009, nine incidents of Flashbased malicious advertisements affected major web sites such as guardian.co.uk and perezhilton.com (both appear on the Alexa Top 500 Global Sites list.)

That has been known for a while. However, I have noticed that using the Flash ads to download malware isn't as popular as it was a few years ago. Today, it appears that the hidden elements that the advertising services use to track the user are what actually download the malware. Most ad blockers only prevent the visible ads from being displayed, so this is a more effective method to infect computers. I haven't seen any way to block the tracking services besides using a custom Hosts file or an add-on like NoScript to block Flash and JavaScript.
