3 Types Of Computer Malware

There are three major types of malware: spyware, adware, and computer viruses. Malware is just an overarching name for computer programs that are not built for the user. They exhibit similar qualities, which usually leads to major nuisances for computer users. But what exactly are the differences between the three and why does it matter?

Spyware  - does not intentionally harm your computer - it gains nothing from damaging a host system. This is because they create backdoors to let others in additional to the computer owner communicate with the computer. Usually, spyware records which web sites you visit; this information is then aggregated and sold to advertisers to allow them to send you unwanted emails and pop-ups.

As a result, spyware should be avoided as much as possible. It is much more intrusive than adware, sending private information to third parties. Spyware often exists as a separate executable program which allows them to scan files on your hard drive, record your keystrokes, and see information in other applications that you use. Some spyware even attempts to steal passwords and credit card numbers as you type them, then send them off to identity thieves.

Adware  - consists of advertising content which is surreptitiously packaged into a program, often without mention, and activated automatically once that particular program is installed into the computer. Then, the adware serves up the advertisements at will on your computer, leading to annoying distractions as you try to accomplish your work.

Signs of adware or spyware infections include pop-up ads that seem unrelated to the site you are viewing. Also, spyware pop-ups are frequently ads for adult content. If you notice your computer taking longer than usual to perform its usual tasks, there's a high probability that spyware has found its way to your computer. When the desktop takes forever to load on startup, your best bet is to scan your computer for potential spyware infections.

Viruses  - are a malicious form of software. They are programmed for one sole purpose - to destroy your computer, either by deleting important data, or replicating as many times as possible to fill up your hard drive, or worse! They also have systems in place to move onto other computers, thereby ensuring that they have more victims in the future.

Currently, many anti-virus programs also provide spyware and adware scanning and removal utilities. But regardless of whether your security suite is an anti-virus program or a anti-spyware scanner, they both search your computer and identify the malware installed on your system. After identification and isolation, they then remove any detected malware. It is wise to regularly update your virus or spyware scanner to ensure that your computer is protected from the hundreds of malware programs spawning everyday on the internet.

Don't be fooled by ads that claim their offering only contains adware as there are usually worse things inside. The adware may in fact be spyware in disguise and are just waiting to be installed to harvest your information. Learn to set up firewalls to block them from communicating with their master and always enable a pop-up blocker to minimize computer infection and ensure the safety of your files.
