US-CERT Cyber Security Tip ST06-009 — Coordinating Virus and Spyware Defense

Hey everyone,

     It’s been a while since I posted.  So, I’m planning on making up for lost time and posting a few articles this weekend.  This first article is about coordinating your Anti-virus and Anti-Spyware programs.  It’s something that comes up occasionally with the people I know.  They always ask me about running more than one AV or Anti-Spyware program at the same time.  So, this article provides the best advice that I’ve found.

     I’ve always told people that you shouldn’t have more than one AV program installed.  I’ve had others tell me that you can, but you should only have one “active” at any time.  What this article says is a combination or middle-ground of both arguments. 

    You can have more than one AV and Anti-Spyware program installed, however you need to research them before you do it.  Make sure that they are compatible with each other (especially if they’re not made from the same company).  And only have one of them providing active “Real-time” scanning.  The other can be used for manual scans on a regular basis.

    One reason for this hasn’t been used before (but is true and obvious).  Each active program uses up some available memory.  So, the more AV and Anti-Spyware programs that you have running, the less memory you have for your other programs.

     I’m still of the mind-set that you should only have one anti-virus, and one firewall installed.  However, you can have more than one Anti-Spyware program.  If you choose to have multiple copies of Anti-virus programs installed, follow the advice in this article.  Most importantly be careful.

    My next article will be over “Recognizing and Avoiding Spyware.”  Have a great weekend everyone.

Patrick.
