Even Trusted Websites can have Malvertising

Malvertising is especially troublesome because it often is activated without any action being taken by the computer user.  As a web page with the advertising is loading, the malware is quickly and quietly infecting the operating system.  Most people are savvy enough that they know to be cautious about which web pages they choose to visit.  Yet, malware is silently hiding even on the most trusted websites, such as Google, YouTube, and Rutgers.  Site administrators are mostly unaware of the widespread corruption being piggybacked through their credible pages because third-party advertising agencies provide the promotional content.  The ads are changed on a fast rotation, through an automated process, based on keywords entered by the user.

What You Can Do

You can protect against malvertising infections by avoiding pop-ups that say you have won a prize for visiting their site, or ones that are offering freebies of money, products or discount coupons.  Read the comments before you click to proceed with any downloads and always install the latest updates for your computer's operating system, installed software and browser plug-ins.  Computer security anti-virus programs such as those offered by Norton and McAfee are always a good idea.

Signs that your computer might be infected include:

  • System runs slowly
  • Applications won't start
  • Files are moved or have disappeared
  • Internet pages open spontaneously while browsing
  • Firewall has been disabled 
  • Anti-virus program turned off or removed
  • Emails have been sent or programs have run without your consent, suggesting that someone else has taken control of your system

If you believe your computer security has been violated, you can start by running a scan using Microsoft's malicious software removal tool that came as part of your copy of Windows.
