In its simplest terms a virus is a disruptive computer code period!
A computer virus almost always repeats itself and spreads by attaching itself to other files. Viruses can be made to host a number of harmful things on any computer from disrupting files to crashing networks. It can even be laying dormant, without you knowing it's there and then attack when least expect it, like right in the middle of downloading a large file or typing a long report.
It can even be made to open at a certain date, sitting like a timebomb until it's time arrives. As you can see it can be annoying at the very least.
I do not want go into all the different types of viruses here because there are so many and more are being made everyday in some dank basement by the Dark Lord.
However, since so many viruses came from unknowingly opening e-mails I would like to mention some basics here:
Never open e-mail attachments unless you know for sure who it's from and that it's safe.
Some mail programs will even ask if you trust the attachment and if you’re sure this you want to do. Your computer software can also scan attachments for viruses.
The danger is that when the attachment is opened the virus can attach itself to your hard drive and damage files. Not only that, it can search your saved e-mail addresses and send itself out to your friends, business partners and whoever is on the list, masking the message to look like a legitimate one from you. It will probably have an attachment too and when opened will infect other computers.
Many people like to download music, video, games or other programs from different sites. If it is a site you dealt with before and trust it may be safe ok, but if you’re not sure you can always run a virus scan on the download before installation. (You will need to check the anti-virus program that came with your system on procedures). This security measure is necessary because some downloads may contain virtues, spyware or adware – these last two can collect personal information, note your browsing habits and spam your e-mail with unwanted ads. Some software sites will offer a readme file that shows technical information on the download (if you like tech talk) as well as contact info.
The better sites that offer downloads will test and scan all there software programs before going online with it. As a last resort you can do an internet search for reviews on that particular company to see if others got burned.
This may sound scary to some but the fact is in this world anyone who owns a computer will have to look over there shoulders for hidden attacks when working with online.
That said there are some things should do to prevent viruses from attacking your computer:
* Download the latest virus definition lists ( files that tell your computer what to scan for) that's used for your anti-virus program.
* Check to see if your internet service provider has tools to stop viruses before they can reach your mailbox.
* Always back-up your computer on CD-R disks or other media in case you loose some or all your data.
* You can scan software for viruses before installing it. (See system manual for procedure)
* Set your security settings at the highest level.
* Check your web browser and e-mail settings.
Doing these things at least every week will help keep your computer up to date on Virus protection and running safely.

Computer Security – It’s Bigger than Spyware and Viruses
Computer security, in basic terms means keeping your computer and the data that’s in it safe and secure. More of our personal data is stored in or accessed from our computer, now more than ever before. Yet most people lack even the basic understanding of how to keep their computers safe and secure. By following just a few simple rules you can dramatically improve the overall security of your computer.
The first thing to understand is what exactly it means to be connected to the internet. Your computer connected to the internet is similar to your house in many ways. There are many ways into your house. Windows, doors, etc. The more windows and doors you have, the more ways someone has into your house. An open door doesn’t necessarily mean you are going to be robbed, but it does improve the chances. Complicating matters, the ones that you think are locked, may not be because the lock is faulty or even the door itself may have an as of yet undiscovered flaw that would allow an intruder easy access to your home.
Your computer has many windows and doors, not all of which are locked. New flaws are being found everyday, often with the fix not coming until days after. Just like you wouldn’t leave your front door unlocked, you shouldn’t leave your computer wide open either. The first two things we will discuss to help with this task are installation of a quality firewall and regularly updating your installed software.
Updating your software is becoming easier these days, especially your Operating System. We don’t have the time here to go into detail about the many ways to update the many software packages you may have or use, but generally speaking the software manufacturer will provide you a way to do this automatically via the internet. A good example of this is the Microsoft Windows Update feature. Be sure to get the updates for everything installed on your computer, nothing is too trivial.
There are two basic types of firewalls and both perform the same functions. One is hardware the other is software. A hardware firewall is probably included in your router if you are using one, while you may or may not have a software firewall installed. To continue our house analogy, a firewall is like building a wall and gate around your home and giving the guard at the gate instructions on who to let in and out. While this does give a great deal of protection, it is not all that is required. Someone may know a way around or under your wall, or even be able to coerce the guard into letting them in.
You yourself may unwittingly allow someone in. This could happen by simply opening an email or even simply surfing the net. Spyware, viruses, trojans and the like are ever more adept in their methods of fooling you and your guards. Emails may come from a trusted friend containing a dangerous virus without them even knowing it. This is where the next layer of protection comes in, anti-virus software.
Anti-virus software is a large category these days. Often these packages come as “suites” including a firewall and Spyware scanner. While most of these programs are very effective in their promised tasks, it is not wise to be lulled into a false sense of security by them. They are simply one layer in what should be a multi tiered protection plan for you and your computer. One last important note about anti virus software is to be sure that it updates on a regular basis. New threats come out daily so check its updates manually to be sure they have happened.
Back to our house analogy, we now have all of our windows, doors and other entry ways locked and fully updated. We have a wall around our house with a guard at the gate and we have software scanning everything that comes in past the gate. Sounds pretty good, but there’s one last security hole we need to address, you.
A large percentage of infections are caused by the computer user themselves. The internet is an ever changing place that requires it’s users to be educated about its use. I’m not suggesting that you need to be a computer expert to simply read your email. I am however suggesting that you take some time to educate yourself on some of the dangers that pop up everyday, and the precautions to take in order to avoid them.
In summary, your computer is a powerful machine connected to one of the greatest things ever invented, the internet. This vast resource can be a dangerous place if you are not properly prepared and informed. Regular software updates, a good firewall, anti virus software and a little education are the basics in computer security. Having and understanding these basics will make your computer safer, more secure and more enjoyable.

Adware: Are Your Business's Computers Secure?
Adware, software dedicated to displaying advertising, can really slow down any business that depends on computers. Adware promoters use some cunning tricks to get you to install their software on your machine. Here's what to look out for.
Adware is, by definition, something reasonable people don't want on their computers. That's why adware can't just come out and ask people to install it. Often, the computer owner is completely unaware of it being installed. But not always.
When adware doesn't want to sneak in through an open window, it will try to trick you into letting it in through the front door. Don't think you could be tricked? Don't be so sure until you've checked out these most common ways people have been tricked into allowing malware to be installed on their machines.
Adware Installation Trick 1: Piggybacking
How it works: malware may come bundled with a legitimate piece of software the user actually wants, such as a game or emoticon. The malware is merely labeled "companion software," without any indication of what it will do.
How to fight it: the fact that adware so often comes bundled with "entertainment" software, most notably the file-swapping program Kazaa, is a very good reason to separate business from personal when it comes to computing. But adware can sometimes comes bundled with non-entertainment software, such as search tools or cracks of legitimate business software. Be very suspicious of any software that comes bundled with other software. Don't installed software that comes bundled with other software unless you know everything that the bundled software does. After all, if the bundled program has anything to do with the program you actually want, why couldn't the software developer just get both programs' functionalities into a single piece of software? Software developers are now very sensitive to malware concerns and will provide a lengthy explanation of just why the bundled software is necessary, in the cases when they actually do need to use bundled software.
Adware Installation Trick 2: Bait and Switch
How it works: since people are getting more and more suspicious of bundled software, the program's developers may simply label it as valuable software, for instance, a browser plugin that supposedly accelerates web browsing (but in reality only shows ads).
How to fight it: again, a suspicious mind is useful in avoiding malware. Ask yourself some questions:
* What will this software actually do? Adware and adware-bundled software often come with very fuzzy claims attached. Sure, it says it will improve your browsing experience, but how? Often, this improved browsing experience just means a browsing experience with more advertising.
* If the software is so great, why is it being given away free? Most commonly, software is only given out free in two cases: if it's OpenSource (designed by a community of developers and not proprietary–OpenSource software is always clearly labeled as such); or simply a come-on for a fuller-featured version of the software. If neither case is true, there's a real chance the software is financed by adware.
Adware Installation Trick 3: Outright Lying
How it works: adware may even be labeled as something else entirely, such as a well-known piece of software or a crucial component of the computer operating system.
How to fight it: this is the trickiest adware of all, and requires extreme caution. You don't want to start deleting any of your program files, much less your system registry entries, unless you're absolutely sure it's malware. Plenty of overzealous parasite hunters have shot their own machines to bits this way. This is one case where you want to be using an anti-spyware program, and preferably a second anti-spyware program to provide a second opinion.
Getting Rid of Adware
Adware is so tricky that trying to uninstall it by yourself could be like a trip into the Matrix. Luckily, there are good anti-spyware programs that tackle adware as well–after all many adware programs are also spyware since they monitor your internet usage.
True, it may feel like adding insult to injury to have to install more software to get rid of software you never meant to install in the first place. But keeping your computer free of adware is just one new cost of doing business.

4 Necessary Steps You Should Take When You are Online
When you connect to the internet you can harm your PC. That is a fact. The reason antivirus software and other similar products where created is to protect your PC.
It is not your fault that you got viruses, however you should take the precaution methods to stop this from happening again.
Keep PC Clean: It is important that your PC stays clean if you use the internet. Clean from the 'bad, harmful objects' that are also known as spy ware, adware or viruses.
There are many different types of harmful objects but luckily there exist also cure to keep your PC protected.
A must use Software: The two most important software you must have are an antivirus and an anti adware. There is no need to purchase 30 different kinds of anti spy ware software...
However you must choose two software which will protect your PC. These will work in the background automatically. Some anti adware products also heal spy ware not just adware.
Schedule Maintenance: The software will block spy ware and adware. However you should also use the software when you are offline. You should scan your
PC using both software at least once every three weeks. That will clean any harmful objects. These objects can make a lot of harm to your PC.
Safety Measurements: We already mentioned that you need two software to keep ongoing protection on your PC.
If you download software/movies/images/videos or any other thing from the internet it is recommended that you scan those items. Before opening them right click on them and use your antivirus to scan them.
Go to Control Panel to turn on Firewall. Firewall is also an ongoing protection which is very important.
Once you have your software installed these protect your PC and you get back the freedom you deserve. Remember that prevention is better than cure.
