This is a continuing problem, and increasing as major websites grow increasingly dependent on 2nd and even 3rd party networks to manage the ad-placement aspect of their business.
Malware-Infested Ads Found on Major Websites
By Jill ScharrAugust 28, 2014
Break out your ad blocker or your NoScript: Malicious advertisements have been discovered infecting the Web browsers of people who visited certain major websites between Aug. 19 and Aug. 22. Users did not have to click on the ads to be infected.
What can you do to protect yourself from malicious ads? First, run a good antivirus program, which will detect browser exploit kits hidden in Web pages.
Next, you could try to use an ad blocker in your browser. You can also enable click-to-play, a setting in modern browsers that bars each multimedia file, such as an ad that plays music or movies, from running unless you give it express permission.
However, both solutions may be incomplete. Some ad blockers "whitelist" certain ad networks so their ads display, and click-to-play settings won't affect simpler ads.
It might be best to install a plugin, such as NoScript for Mozilla Firefox or Script Blocker for Google Chrome, that blocks all executable browser content. Users will generally be able to temporarily or permanently allow content from certain sites, while continuing to block others — such as that from ad networks.

I believe this has been prevailing from the past 7 to 8 years. Earlier, when i used to use windows 6 or 7 browser i was also a target for such malware. In fact my desktop which had no AV protection was struck by such malware. I had a terrible time for almost 20 days. Then after using adware antivirus, i got rid of it a bit. But again i failed. So, i had to format my hard drive and reinstall the oS.
Nowadays, with windows 7 i am bit comfortable with Win IE 11. But sometimes still the problem persists. But my AVG protects me from such malware to a certain extent. This happens when i visit some online shopping websites
