How to Get Rid of Malware - What is Malware and How Do I Get Rid of It?

Malware is becoming more and more of a problem these days as we shift more of our lives online, so knowing how to get rid of malware and how to avoid it in the first place will stand you in good stead for the future and help you to enjoy more of your online experience.

What Exactly Is Malware?

Malware is an abbreviated term for "malicious software", and refers to a wide variety of "virtual nasties", as I like to call them. These nasties can be sometimes be difficult to get rid of and include things like:

Worms - these "burrow" into a system and cause damage often via email, and use your email contacts or address book to continue the process.

Trojans - harmful or annoying software that comes in by the back door, often disguised as a normal file.

Spyware - often comprising keyloggers and screen capture systems, designed to track your online movements and extort personal details, like bank account numbers, social security numbers etc. for the purpose of online fraud.

Adware - a normally harmless but annoying piece of code or software that monitors your online movements and presents advertisements linked to your browsing habits, generating revenue for the creator of the code. They are often linked with illegal or illicit sites such as pornography or hacking.

The damage these parasites cause can range from slight slow downs in your computer's performance, or annoying pop-ups, all the way to harvesting your personal details and information and even the irreparable damage to files your operating system as a whole.

How Do I Get Rid Of Malware?

Now that we've established what it actually is, we can get on to the task of how to get rid of malware.

Get An Anti-Spyware Software

While many people may have an anti-virus software, these days it is always good practice to have an anti-spyware application too, as this will create a double barrier of protection and take care of all the latest malware and virus definitions. If you don't have an anti-spyware software yet, you can find some recommendations and get a free scan at my website, at the bottom of this article.

Switch Off Your Internet Connection and Run A Scan Immediately

Run your anti-virus and anti-spyware scanning software immediately if you suspect you may be infected. Running both softwares will stop malware "falling through the net". Switching off your internet connection will avoid any slow down and prevent any new attacks to your computer, as well as stopping the malware that may be on your machine from communicating or spreading itself to other computers.

Once Detected, Zap It!

Once your software has detected the rogue in question, follow the instructions on how to get rid of the malware. Simply deleting it may not work - if it's a program file it will need to be uninstalled through the Add/Remove Programs utility in your Windows Control Panel. If the parasite has made changes to your registry, you may need to use a registry cleaner to help restore things back to normal, and get rid of the malware completely.

How Do I Avoid Malware In The Future?

Here are some good practice tips to help you avoid getting malware in the future.

Always Use A Firewall

The firewall helps to prevent attacks against your computer without you knowing. Making use of a firewall is essential when going online today. In fact if you're not using one right now, make that your first priority. Windows computers all come with a default firewall which is pretty good, so get that set up immediately if you haven't already done so. Most anti-virus software and anti-spyware softwares come with some pretty beefed-up firewalls these days so there's no reason to be without one.

Use Anti-virus Scanners To Check All Downloads and Emails

All downloads and emails should be run through your anti-virus software before being placed on your computer system, even if they're from a trusted friend. This will eliminate many possible problems.

If you're running on Windows, and downloading executable files, .exe files, (such as programs or software) you should often get a dialog box telling you whether the site you're downloading from is authenticated by Microsoft. While this is not 100% effective as not all legitimate sites have been through the authentication process, it can help you think twice if you have any doubts.

Be Careful What Sites You Visit

Particular care should be taken on Torrent and Peer-2-Peer file sharing networks as these have become a haven for hackers to spread their plagues via seemingly harmless Trojans.

This goes without saying really, but please avoid illegal or immoral websites as these are where the most dangerous and lethal virus and malware attacks occur. However, it is always good practice to follow the above tips and make sure your anti-virus and anti-spyware systems are up-to-date, just in case you get redirected to any of those questionable sites...yes, this does happen.

Define Computer Hardware

It is quite well known that the working of the computer is pulled by hardware and software. One can define computer hardware as the electronic, magnetic, and electric devices that carry out the computing functions. Hardware is the physical components of the computer like microprocessor, hard disks, RAM, and motherboard. The peripheral devices such as monitor, mouse, keyboard, printer, and speakers can also be included in the list of hardware parts. The programs that run on the computers like Windows, C++, and Photoshop are the software parts of the computer. A good example for an easy understanding of hardware-software definition is music CDs. The actual compact disk is the hardware, while the songs and music in the CD are the software parts.

There is another way to define computer hardware. Hardware devices are the executors of the commands provided by software applications. For example, let us see what happens when you click the print button of the web browsing software. The software application provides a command to the processor, which is the central part of all computer hardware. Processor in turn checks for an attached printer. If the printer is ready, the software will get a positive response from the processor. Then the software application provides instruction to the printer via the processor to print the web page. In that sense, hardware parts are the foot soldiers and software applications are the commanders in the digital operation that takes place within a computer.

The main player of computer hardware is undoubtedly the microprocessor. It is the sun in the solar system of computer hardware devices. It is the central component and all other components work around it. It is an integrated chip on which a number of functions are incorporated. Two specifications determine its efficiency. One is its processing speed, which is measured in gigahertz. The other is its bit rate. Commonly available processors are 32 bit and 64 bit. The bit rate is a measure of the efficiency of a processor to carry out multiple operations at the same time.

One cannot define computer hardware without mentioning the two types of memory used in computers. One is permanent memory. It refers to the magnetic storage capacity of hard disk. It is measured in gigabytes. The second is RAM or random access memory. This memory is able to store data only when the computer is switched on. The memory will lose all the data when the computer is switched off.

Another important product that one should mention when one defines computer hardware is motherboard. It is the electric and electronic circuit board on which all the other components are inserted. There are several other kinds of products such as sound card, video card, network card, and modem that complete the hardware spectrum.
