information to know


Why does my PC get slower every passing month? Nearly every month, Microsoft issues security patches to protect us from things the "bad guys" are doing.   Microsoft has to re-engineer the way Windows works to fix problems, bugs, and vulnerabilities, which often has a negative effect on performance.  Often times, in which you may be aware, fixing one problem creates another problem. It's tricky work!   After Windows XP ServicePack 2, there are about 75 additional security patches.

In addition, how many programs you install on your Computer, whether or not these programs are running all the time have impact.  Your PC will generally never run as fast as it did when you first bought it, because installing programs and connecting devices such as Printers, Scanners, and accessories all impact the PC.  Similarly, if you run four applications at once, say Word, Outlook, Excel, and Powerpoint, Windows has to allocate resources to service each program, which slows down your PC.

Security software, the very programs trying to protect you from the bad stuff from the web, e-mail, and other Internet Sources can have a tremendous impact on PC performance.  In situations where we have verified there are no viruses, trojans, or other malware running on your PC, we have to take a look at the event logs and rely on our own experience and intuition to see what may be going on.

In a 15 month period, viruses increased from 99,165 to 168,923, or about 4,650 viruses each month.   In the period from January 2006 to November 2008 (23 months), new viruses increased to 13,315 per month.   This means a typical PC owner is having to replace their PC sooner, because the virus explosion is causing Antivirus software go grow exponentially, at a much faster pace. The more viruses to be detected, the larger the footprint and the more system overhead.

Common causes for Computer Slowdowns: Replacing and installing a new security product without uninstalling the older previous software. Old antivirus (or Internet Security) software cannot coexist on the same computer, even if the old product has expired.  Generally speaking it is okay for different Antivirus and Antispyware software from different manufacturers, however that line is beginning to blur as Antivirus software crosses into the realm of Antispyware, and Antispyware software implements features (such as process monitoring and registry blocking) characteristic of Internet Security Software.  If in doubt, consult the Software manufacturer's Support site.
