Luqnet.com: How Computer Viruses Are Spread

How will you feel? You wake up one day and realize that you have a virus on your computer, ?and you don?t know quite how to get rid of it.

Most people these days understand

what a virus is and how harmful it can be, but they are still somewhat unsure how computer viruses spread. The truth is that there are many different ways in which a virus can spread from computer to computer, but let?s take a look at the most frequent ways in which people run into viruses, spyware and Trojans on the Internet.

Rogue Websites

It is depressing to know that you may become infected with spyware or a virus by doing nothing more than simply visiting a website, but it is true. Many adult websites, gambling websites and other less than trustworthy websites will attempt to automatically access your computer when you visit them. They often install adware bugs that will cause a flurry of pop ups to appear on your screen. This adware will often allow for other programs with even more nefarious purposes to be installed and before you know it, your computer will be swamped.?

To protect yourself from these, adjust the settings on your antivirus software and firewall so that no outside connections can be made and no programs can be installed without your express permission.

Networks

If your computer is connected to a home network or if your work computer is part of a larger network, you may find yourself with an infection through no fault of your own. Someone else on the network downloaded a bug by accident, and within minutes, the entire network could be infected.?

There isn?t much you can do to stop these kinds of infections, short of having your network administrator ensure that everyone?s antivirus software is up to date so that the invading bug can be removed as quickly as possible.

Email attachments

The world became familiar with the phenomena of email attachments carrying viruses thanks to Microsoft?s Outlook Express automatically opening every attachment to every email you received a few years back. Now that email clients no longer do this, the infection rate from email attachments is significantly lower, but it can still be a common problem. The golden rule is that if you don?t know what an attachment is, don?t open it.?

To this day, many email users never open attachments, no matter what. You don?t have to take such drastic steps to protect yourself, however; simply use common sense when opening attachments in your email.

Infected Boot disks

?Now that hard drives are obscenely large, the overwhelming percentage of us don?t bother to use boot disks anymore, but a virus can still be spread if an infected disk is in your hard drive and you attempt to restart. When you start your computer, your machine will always check your drives to see if a disk with boot information is present. If one is, your computer will likely automatically attempt to boot from the disk and not from your drive. If a virus is present, it will often be activated and you will become infected. Always know the status of any disk you put into your drive.Phishing Schemes

Learning how computer viruses spread is important to keep yourself, and your personal information, safe online. Phishing schemes are one of the chief ways in which people end up with their identity stolen and a computer fill of viruses. A phishing scheme starts when you receive an email from a website claiming to be your bank or Credit Card Company. You are asked to click a link and log in, but the truth is that you?ve just given away all of your personal information. Often times, when you visit these sites, spyware, adware and viruses are automatically installed on your computer. This also works like the Rogue Websites.

The smartest thing you can do is to simply call your bank or credit card company if you receive an email saying there is a problem with your account instead of blindly following links in your email.

Hackers

The Internet today is a much more law abiding place than it was ten years ago. Not only did most people not have antivirus protection and firewalls that could stop incoming attacks, most people didn?t even know what they were. Today, people understand the value of good online protection, but hackers can still pose a problem if you allow your protection software to lapse.?

The best way to beat hackers is to ensure that you have a firewall and up to date antivirus software.

Infected Software & Fake Anti Virus?

One of the great things about the Internet is how many free games and programs there are out there, but these free programs often come at a price. Too many rogue websites intentionally infect their freeware (like Kazaa) with Trojan viruses so that you unknowingly infect your computer every time you download a free game or piece of software.?

The key here is to only download freeware or shareware from a trusted source that always ensures your safety.

Also, the most frustrating ways to become infected with a virus or worm. There are many antiviruses and anti spyware programs you can download for free on the Internet and a surprising number of them actually do exactly the opposite of what they claim. The product websites make outrageous claims that their product can protect you from a whole range of threats, when, in reality, their product will only make things a thousand times worse.?

Only download antivirus programs from trusted sites or from websites that you know are completely legit.

?Instant Messaging

It is difficult to find a computer in this day and age that doesn?t have at least one instant messaging service installed on it. Unfortunately, these programs are often targets of hackers who see an easy way to trick people into clicking links that lead them to rogue websites.?

Only chat with people you know and never follow links to sites that you don?t recognize. You should easily be able to keep Internet worms, viruses and other bugs at bay.

Note all this simple ways that viruses use to attacks your computer.

Unfortunately, we are sent viruses through our email from people that we know and trust. The social networking site Facebook has had to battle this very problem when their serves get a bug and automatically send out emails to everyone on the system that are infected. Often times, these emails are extremely generic sounding and come with suspicious attachments, but people often open them anyway since they have come from a friend or from a site they trust, like Facebook. Remember, if you get an attachment with an .exe extension or a .dll, don?t ever open it.

Finally, learning how computer viruses spread is the best way we can put an end to their reign of terror online. It is only with the right knowledge and the best antivirus protection software that Internet users everywhere can beat online bugs for good.
