The past weeks have seen some interesting software that got installed on computers that started to interfere with previously installed anti-virus/security software.

“How did it get in? I don’t remember downloading anything.”

Recently i started a re-install of adobe reader, adobe flash and their shockwave products. During the installation I found that these products also had pre-checked by default, installations for Mcafee and Norton scans.

Google Apps actually had another full antivirus package pre-checked by default for installation during installation of other Google products. The installation of this antivirus package actually brought down the previously installed BitDefender suite. The Vista computer was subsequently infected with 25 different infections after this point – the computer was not even operable when It came into the shop.

What I am advising clients is to CAREFULLY read the screens as you install software from the net. UNCHECK all “free scan” software that may be included with other software as this will interfere with your existing security software.

In the case of anti-virus/intenet security software, more IS NOT better. ONE good suite/package will work better than two, three, or four. Once more than one package is installed, they start working against each other and actually leave holes wide open for attackers to gain control, load their viruses in and render your data vulnerable and eventually your computer inoperable.

Currenlty I have been using Kaspersky Internet Security Suite on all of my in-house computer. It has stopped all things evil and trust me, I work hard to infect my computers to ensure that the products work as advertised.

Kaspersky can be found at buy.com for about $35.00 shipped for three licenses.

If you have questions, please leave a comment or send me an email.
