My computer is slow. What is the reason for this?
Posted on: August 12th, 2008
Basically there are a couple of reasons:
First one is: viruses. These are programs that are running on your computer in the background without showing anything on your screen. They use up your computers resources and thus making it slow.
Second one is: too many installed programs. Unfortunately there are a lot of software that installs components that start every time that you restart your computer. These are responsible for the long wait when you start your system or log in. For example AOL is a bad offender on this. It starts 3 or 4 components which stay in the memory afterwards.
So if you want to have a fast system then you need to get rid of these start-up programs. In fact only very few are actually needed, if any. Actually we have computers which have no extra programs starting up automatically and they work just fine (and fast).
Third one is: certain antivirus software. We’re sorry to say but we found several cases where the antivirus software caused the computer to run slowly. It’s particularly common with Comcast customers who can get McAfee for free with their high speed internet service. For McAfee to run well without noticeably affecting the performance of the computer it needs a system with a very fast processor and a great deal of internal memory. Downloading it to a system designed for Windows 98 almost certainly will result in a very sluggish computer. Another offender is Norton Internet Security
The reason for this is the use of system resources by these softwares. They keep many functions of the system under watch and they keep their virus identification databases in the memory. This results in less processor time and memory available for other applications. So if there are plenty of these resources you won’t notice much slowdown but if you are not so lucky then your system could get extremely slow.
The brute force solution to this is to get a better computer, or more memory. However there are another alternatives, another, freely available antivirus software that does not ‘hog’ system resources while provides nearly as much protection as these ‘giants’. With some additional security configurations the system can be made very safe without the degradation of performance.
