It never fails to frustrate. You are working hard on a project and just as you are about to click that save button, suddenly your system begins to run very slow or worse, it locks up all together. Another day's worth of work down the tubes. Malware is what causes a computer to be slow and it is the bane of every computer owner's existence (what cause a computer to be slow ' repair with registry cleaner).
Malware is short for malicious software and it is a coverall term for many varieties of hostile, annoying, and intrusive code. This software is designed to infiltrate your computer system without your consent and it includes viruses, worms, trojan horses, spyware, adware, and crimeware. There are no common features denoting malware, instead its designation is determined by the intent of the programmer. And, this malevolent intent is on the rise. Several computer security companies claim that the amount of malware produced in 2007 is equal to that of the amount produced during the previous 20 years.
Probably the most commonly understood type of malware is the computer virus. A virus is a computer program that can copy itself (reproduce) where by it infects one computer after another through the use of executable code introduced by host (usually another legitimate type of software) to the target computers. In other words, it 'piggy backs' on a real program and is executed when that program is used. The virus then reproduces itself and piggy backs on another program.
Some viruses are attached to email. These viruses replicate by automatically mailing itself to people in the victim's address book. These viruses then launch when the new victims either open the email (or, in some cases, just preview the software in using their email clients). Then replication begins again.
The word 'virus' is used interchangeably with worm and trojan horse, but worms and trojan horses are different from viruses. A worm exploits security loopholes to spread to other computers without the need of a host. Trojan horses are programs that seem to be harmless but have hidden agendas. While these sound like viruses, these pieces of code do not replicate automatically.
Adware is short for advertising-supported software which is used to automatically download and display advertisements. These programs are piggy backed on other forms of software, but unlike a virus, they are not capable of reproduction. Many adware codes are bundled into legitimate software and are used the software developers to offset the cost of distribution of their programs. Adware, while very annoying, is usually not malicious. Spyware, on the other hand'
Spyware is very similar to adware in that it is piggy backed on other programs but not self replicating, except that instead of being a marketing tool, it collects information about the computer user without his or her knowledge. Spyware collects surfing habits, redirects web browser activity (taking control from the user), and changes computer settings (resulting in slower connection speeds). Spyware can change your home page, prevent you from connecting to the internet, and make your other programs non-functional. Spyware is used to steal personal information such as credit card numbers and bank account information.
Spyware can also be adware in that it will spy on what the user does with his or her computer and then download and display ads that are more likely to be well received by the user. Spyware is not a virus, but it will exploit an infected computer for commercial gain. Many a spyware has been installed on computers via a worm piggy back.
Spyware is also the most likely culprit for a system running slow. It creates significant unwanted CPU activity which slows down all programs on your computer. This excessive CPU usage can freeze programs, cause your system to not boot, and even cause system-wide crashes. It uses up disk space and creates a lot more network traffic than normal. Chances are if you have one spyware on your computer, then you have many.
With all of these threats to your computer functionality, how do you protect yourself? The most obvious answer is anti-virus software followed up with adware and spyware removers. But, gaining popularity solving what cause a computer to be slow is to repair with registry cleaner. A registry cleaner is a utility designed for a Windows operating system and it removes redundant and unwanted items from your registry. The advantages of a registry cleaner is that it may improve the performance of your computer by getting rid of superfluous code and it many improve application performance by repairing registry keys. The disadvantage is that many registry cleaners cannot distinguish between critical errors and benign registry information. To make matters worse, some registry cleaners are just trojan horses in that they have the hidden agenda to install other malware right into the registry. It would be wise to weigh all your options carefully before cleansing your system to improve performance.
