Tips to Avoid Malware

Certain websites and programs should be avoided on both your home and work computers. Given the prevalence of malware, cryptographic hijackers, advertising and marketing software and other malicious programs, this list can serve as a general guide as to what types of websites and programs can pose a risk to your computer and information. Please be aware that even legitimate, well-maintained business and institutional websites can occasionally promote harmful software, so no list can guarantee that you will never encounter a virus or other malware while Internet browsing.  Awareness and making a habit of following best practices is your best defense.

There are additional protections you can use, such as browsing the web only when using a non-administrative computer account. For more information on protecting yourself while online, go to or contact your departmental IT Support or UNH Information Security Services.

Dangerous Websites: 

  • Pornographic sites
  • “Free Service” third-party sites
  • Music/Video/Software piracy sites offering “free” or “cracked” downloads, “Warez” etc.
  • Peer-to-Peer (P2P) sites
  • Obscure search sites. Use mainstream search engines such as Google, Yahoo or Bing.
  • Websites that require a download to access or use, or which try to force a software installation
  • Web-based Flash or Java games
  • Pay-To-Click services
  • Coupon or “Deal” sites
  • Third-party fee-based sites offering services that are often obtainable without cost from the original source. These include but are not limited to credit report sites, government information, and public databases, texts of state and federal laws, travel information, maps and directions. 
  • Social Media Quizzes (…for example, popular Facebook quizzes like "Which Type of nnnn  Are You?". These are typically data mining scams.)
  • Free People Search Sites

Risky Software

  • Icons or Icon kits
  • Screen savers

  • Wallpapers (static or automatically rotating)
  • “Exclusive” offerings
  • Downloaders for music, movies & hacked programs

  • Search Engine Settings “Protectors”
  • Coupon generators
  • Product Key Generators
  • Electronic Greeting Cards
  • Animated desktop characters or animals (“eSheep”)
