The article is for computer users that are not computer literate on malware. 

Many of the computer problems the users face when using a computer is malware.  Malware are programs that enter a computer without the computer owner’s consent.

The two most common type of malware are viruses and worms. Viruses are files that are attached to a legitimate file and reproduce themselves.   For example, a word document, which is a legitimate file, can include a virus that can be spread by inserting a removable storage device to the infected computer.

A worm malware is different from virus. A worm, once in your computer, can travel on it’s own to more computers if it is part of a network.  A worm is a program that finds holes in a program or operating systems. When the computer is infected with a worm, it can delete files or it can allow the computer to be controlled by someone else.

Other types of malware are Trojan Horses, rootkits, and logic bombs. A Trojan horse is a program that hides from the users and runs behind on application that the user is running. It can be a music file that the user downloaded from the internet and while listening to the music the Trojan horse is doing something else like scanning for passwords or credit card numbers.

A rootkit is a program that hides in the root (main drive or c: drive) and many times is undetectable and is used to hide viruses and worms.  The rootkit is limited to one computer and it has no way of spreading to other computers.

A logic bomb is a program that is activated until something triggers it. The logic bomb can be triggered on someone’s birthday and it can be set to damage files like payroll or employee information.

Another group of malware is spam and spyware. Spam is usually unsolicited e-mail and advertised e-mail. Spam goes via internet when using e-mail. Spyware is software that is installed on your computer to collect personal information and used for malicious purposes.

The best way to protect your computer from these types of malware is to buy or download an antimalware software and to enable the computer firewall that is built-in. There is free software that you can use, but it will not protect a computer from all malware threat because they come with minimum protection. The website has many free applications that can be used to protect your systems from malware. For example, CCleaner helps the computer run faster by cleaning unused data from the hard disk and by removing the history from the browser.

Malwarebytes is another anti-virus and anti-malware that helps protect your computer. Kaspersky is also an anti-virus and anti-malware that protect the computer from viruses, Trojans, worms, spyware, adware, scans files, email, and internet traffic. 

For full protection for your PC, it is advisable to buy the full package antimalware software, for example, Norton, McAfee and AVG. You might pay approximately fifty dollars per year for an anti-virus. It is better to pay fifty dollars than to pay so much more on repairs every time your computer crashes doe to malware issues.  An important thing to remember to keep your computer safe is the update the antivirus, the operating system, and programs that are used in the computer.
