This is the third in a series of articles highlighting reasons why we need a new model for anti-virus and security solutions.

Reason #2: the Desktop Security Software Risks

The risks of placing software on the desktop are such that I will be breaking this article into two parts.

There are many advantages to putting security and anti-virus software on the desktop. They range from efficiency to money. Under previous ways of thinking if I can capture security and virus problems at the desktop I can prevent them from going any farther. That works well in a non-connected environment. In the connected environment it makes more sense to centralize the software and monitor connections in and out. Basically “firewall” all the appliances from each other.

In a previous article we discussed the security risks inherent with desktop software designed to be the protection layer between you and all those bad people out there on the Internet. Here now we will discuss some more mundane issues regarding the risks of putting security software on the desktop:

Drag

Drag steals clock-cycles from your processes so that it can run in a higher priority mode. Anti-virus software especially places a drag on your computer. Depending on your settings (and the default settings are usually very aggressive), every time you run a program or open a file, real-time file scanning takes place and your files are scanned for viruses. This slows down your processing. Accessing larger files takes longer. You can see a discernible lag time between when you start a program/open a file and when you can actually access it.

Compatibility

After the obvious issue of “drag” is compatibility. Often security and anti-virus rules get in the way of your doing business on your computer. While you may get away with using older versions of such packages as Word, Sims, Photoshop, etc. on your computer with the new XP operating system, it’s unlikely your security software will be completely compatible. Why? Many packages rely on very low-level functionality to be able to do the tasks they set out to do. Anti-virus packages have to be able to operate at a level closer to the hardware than most packages. They need to do this to prevent virus software from taking precedence from them. While many packages offer backward-compatibility the opposite is not true: forward-compatibility. There are several reasons for this: a package written for Windows 98 will not anticipate all the changes to the operating system that are
