DACS General Meeting
Meeting Review:
August 2011—Security Risks on the Internet

By Patrick Libert

Bob Gostischa’s opening comments were a wakeup call.

Global Internet users are numbered in the area of 2.1 billion with approximately 272 million in the United States.

85 percent of all new virus infections come from the Internet with 6 out of 10 originating from “legitimate” web pages. Given that percentage, it is very likely that we have all been exposed to potential security breaches on our own computers. Small sites stay infected for the longest time while large sites clean up quickly but it is virtually impossible to identify an infected site before one access it.

There were 5 million infected domains reported in the last twelve months; fifty thousand virus signatures detected per day and one billion cumulative virus reports per month. Do you still feel safe?

Whereas past threats were from the like of viruses with colorful names such as the Melissa virus, the I Love U virus, and the My Doom worm, present threats originate from cyber criminal groups and infections from malware with the sole purpose of stealing your personal data and identity.

How can we protect ourselves? Enter Bob’s favorite antivirus software Avast! This antivirus program is available for a free download, which, according to Bob, should be more than sufficient to protect the average user from malicious intrusion. It is important to remove any other antivirus program on your computer before installing Avast. Their handy guide will walk you through the procedure.

Avast uses a combination of the traditional antivirus programs such as:

  • Identifying virus signatures,
  • Heuristics – which detects virus-like behavior,
  • Behavioral – a more complex heuristics that analyzes the entire computer.

Bob also suggested safety tips for social networking:

  • Use strong passwords that are unique for each service,
  • Keep your antivirus software up-to-date,
  • Install updates in a timely manner,
  • Manage your privacy; don’t expect the site to do it for you,
  • Avoid third party applications.

In closing, Bob recommended the following four additional antivirus programs which are available as follows:
