Malware May Be Hard At Work On Your Computer

If you’ve been using a personal computer for some time the word “Malware” gets on your nerves. Malware is the nice term for malicious software, anyone that has had their PC corrupted by it will use a different choice of words. Malicious software includes viruses, adware, spyware, and Trojans.

If you don’t take precautions they will take over your computer.

Viruses are probably the most common type of malware. Viruses can do all kinds of maddening things to your computer. They can erase all the files on your hard drive, cause your computer to close windows without reason, they can eventually cause your system to not even turn on.

Adware is another type of Malware that is not quite as openly malicious as a virus but can be just as annoying. Adware is a type of software that people inadvertently download onto their computer.

They may download a screensaver or a video game and before you no it your whole desktop has changed. Adware is used to monitor a persons surfing habits so that the person can market specific messages to them. If you’re getting a lot of pop ups and banner advertising, it’s probably Adware at work.

Spyware is similar to adware but in addition to monitoring your surfing it can also record your keystrokes. The real scare to spyware is that it is looking for you to put in personal data such as financial information, like a social security number, credit card numbers, banking accounts. Like adware, spyware usually finds its way onto your hard drive through some sort of freeware download.

Trojans are some of the most dangerous types of malware.

Many Trojans. are downloaded to your computer by hackers and steal your personal and financial data and then report it back to a hacker database. Most trojans are sometimes downloaded by clicking links in email that look normal but are really hyperlinks to hacker databases where the Trojan is then downloaded to your computer.

The good news is that you can protect your information and your computer by using anti virus or anti malware software.

If you have a specific problem with one kind of malware, you might want to buy a specific product, but for all round protection, virus software usually works the best.

Virus software works by scanning your computer files, searching for viruses and malware files. Scanning your computer files can take a few minutes to a few hours depending on how big your hard drive is. Once a virus or malware file is found, the virus software puts the file in an isolation area. At the end of the scan, the virus software reports the list of any malware files found and asks what you want to do with the files. You can then erase all the files or keep them isolated until you know what they are.

Virus Overview

Computer Viruses are one of the biggest “bogeyman” of the Internet, and with attacks by Melissa, ILoveYou, Nimda, and Michelangelo, there are damage estimates and virus warnings all over the Internet. But what are they really?

A virus is a program that spreads to other computers. Like all forms of malware, it both runs without the user’s knowledge or permission and it can interfere with other programs that are trying to run on the same computer. Some viruses also carry a payload, like ticking time bombs. On a given date, or after a certain time after the computer is infected, the virus will “trigger.” This trigger can damage files, erase drives, or attack other systems over the Internet.

Viruses have two major goals. First, they need to be run and installed on the infected computer, and two, they need to spread to other computers. And they need to meet these two goals without alerting the owner of the computer.

There are a wide variety of ways for a virus to infect a system. Many early viruses used the “boot sector” of a floppy disk as their infection point. If the user powered on the computer with an infected floppy disk in the drive, the computer would try to boot from the floppy.

The virus would infect the system, but make it look like the computer had tried to boot from a blank floppy disk. The virus met both goals at the same time, because every time a new disk was inserted into the drive, the virus would put another copy of itself into the boot sector. Today, floppy disks are far less common, and boot sector viruses have all but disappeared.

One of the most common infection routes today is by email attachment. Many viruses today will even search the address book and send out emails without the owner’s knowledge.
