Microsoft Internet Explorer (aka ie) had been in version 6 for a long time. Recently, they released version 7. Essentially, they adopted many features that have existed in both Opera and Firefox for years. The engineering efforts on the Microsoft Internet Explorer engineering had been placed on other projects, abandoning growing security concerns directly caused by using Internet Explorer. Consequently hackers and virus builders have learned to exploit it to steal identity and take control of your Microsoft Windows operating system.
The most vulnerable feature of the IE browser is something called ActiveX. The advantage of ActiveX was while surfing the Internet, the browser will automatically download and install programs on the computer. The disadvantage is there is nothing stopping a virus author from using it to install a destructive piece of software, or a marketing company from installing software monitoring your web surfing activity.This single aspect of ActiveX is the reason many computers become infected.
Menlo Technical promotes Firefox and Opera to stop the potential hazard of automatic virus downloads, because these browsers do not use ActiveX, which will completely remove the exploit.
There are OTHER browsers besides Opera and Firefox to replace Internet Explorer. Many are just wrappers that use Internet Explorer with some protection. These wrappers are still trying to interact with ActiveX, and are still susceptible to automatically placing viruses on a computers.
Apple recently offered up their Mac OS X browser Safari to run on Windows machines. This is available through Apple, and is a viable alternative to IE.
Menlo Technical has been installing Firefox on almost all new and repaired machines. It has proven to be one of the smartest and easiest ways to protect Microsoft operating systems like Windows XP, Windows 7, etc.
