How safe is your computer? Could you be in danger of getting a virus on your system? Just how real is the danger? What steps should you take if any?  While visiting with a one of my students, I became aware that her anti-virus software was over seventeen months old and had never been updated. Upon informing her that she should update her anti-virus software regularly, she was totally surprised. Furthermore she had no concept how essential this was to ensure her system’s safety. Therefore I thought it wise to write about some of the precautions you should take to avoid becoming infected with a computer virus. While there are many ‘virus’ hoaxes, and please do not pass any of these hoaxes on as these may actually contain viruses, computer viruses do pose a very real danger. Therefore I’ve listed a few preventative measures that you should take to ensure computer safety. 1. Do install an anti-virus software program and update it often as there are new viruses discovered everyday. I update my anti-virus database daily. At least weekly should be a goal.

If you are not updating perpetually, it is like having an insurance policy and never paying the premiums. In no time at all it would be worthless. 2. Be wary of email from strangers. Never open an email with an attachment from a source that is unknown or suspicious. Virus containing emails can be very persuasive in the subject line. Do not let your curiosity be aroused. I prefer an anti-virus program that has the ability to  check all email sent and received. If you update it often, this should keep you safe, although  nothing is 100% secure. There are good programs that offer a free version for personal use. These programs generally allow continual updates. Some may require that you register again at the end of year, but the software and updates will still be free. Two such programs are: AVG anti-virus, Free edition  Free avast! 4 Home Edition For more options and reviews on programs you can do a search on google for free anti-virus.  3. Do exercise caution when downloading files from the Internet.

The motivation behind hackers has evolved noticeably over the last couple of years. Developing harmful viruses is less about oragging rights?or satisfying the creator’s ego and is becoming more and more about generating profit or commercial return. The destruction of data on your computer or corruption of programs you use is a common side effect and what people have traditionally associated with a computer virus. The reformatting of your computer  : drive? especially at work, and the loss of valuable data used to be an incredibly painful experience. The widespread deployment of data back up solutions within companies to comply with legislation and other factors means less and less valuable data is now stored on your computer’s local hard drive. More importantly for the virus writer this attack does not generate much tangible profit so there is not much motivation to develop more sophisticated programs to counter improved anti virus applications and corporate network security. However, there is profit for the virus writer in turning your computer into a spam distribution machine.

pam is email sent without the permission of the person receiving the message. Hackers gain control of your computer through a Trojan Horse which gives them the same access rights as the user. Once your computer is controlled by the hacker it becomes known as a mombie. A group of zombie machines is known as a hotnet. By controlling a botnet a hacker can generate profit in a number of ways. The botnet can be used to exhort a ransom from a company by threatening launch a damaging ristributed Denial of Service?(DDoS) attack against its web site. The botnet can also be hired out to other hackers. The most common way of profiting from a botnet is to use it to send out spam email. According to the security software company Sophos over 50% of all spam email now originates from botnets. Hackers use spam email to drive traffic to pay per click advertising sites or distribute virus programs further. Using a zombie computer helps cover their tracks. The drive for generating profit is clearly evident in a new form of virus dubbed  ansomware by security experts which started to appear in 2005.

Computer viruses are deadly.  They often spread without any apparent contact and can be a nuisance, or even worse, fatal to your computer.  Individuals who create these viruses, estimated at 10-15 new ones a day, are the electronic version of terrorists.  Their goal is to inflict havoc and destruction on as many people as possible by disabling, stealing, damaging, or destroying computer and information resources.  Often, they have no specific target in mind, so no one is safe.  If you access the internet, share files or your computer with others, or load anything from diskettes, CDs, or DVDs onto your computer, you are vulnerable to viruses. Fortunately, there are good guys working just as hard as the hackers to develop cures for viruses as quickly as they send them off into cyberspace.  And there are many things you can do to keep your computer from catching viruses in the first place. Defining Viruses: A virus is a small computer program that can copy and spread itself from one computer to another, with or without the help of the user. 

However, viruses typically do more than just be fruitful and multiply, which is bad enough in itself because it hogs system resources.  Anything else viruses are programmed to do, from displaying annoying messages to destroying files, is called their payload.  Often, they cannot deliver their payload until an unsuspecting user does something to make the virus execute its programmed function.  This could be as simple as clicking on an innocent looking file attachment with the .exe (executable) extension. Catching a Virus: Most viruses are spread through e-mail attachments because it's the easiest way to do it.  Although Macintosh, Unix, and Linux systems can catch viruses, hackers are particularly keen on exploiting the security weaknesses in anything Microsoft, particularly Microsoft Outlook and Outlook Express.  Because of the popularity of this software, hackers get maximum bang for their buck, and they probably get some satisfaction from continually reminding Microsoft that being big doesn't mean you're perfect.

We may give bad names on worms, virus and trojans, but if you really look into them, computer virus, trojans, and worms are actually a masterpiece. Not only that they prove that we really are subject to disaster as people who depend on technology, noting that a most lethal virus not only was able to devastate internet network with multi billion dollars loss, and also that as a social community, we are all becoming connected very closely with each other through the internet, confirmed by how quickly a virus can spread.

Storm worm, first spread on January 2007. By October, estimated infected computers were topping 50 million! Have you ever heard of the worm MyDoom? In only one day, January 2004, it was estimated to have infected hundreds of thousands of computers!

If you contrast the damage it can cause with the code size and sophistication of a virus or worm, those numbers are astonishing. Computer virus programs are very plain and extremely small in size, yet they can cause almost boundless damage.

These are some popular types of malicious softwares:

- Email viruses. Spreading through file attachments on emails, this kind of virus duplicates itself by sending emails with the same attachments to every addresses it can find in the address book of the compromised computer. Very malicious ones can launch upon being previewed in the email client program.

- Worms. A worm software multiplies via networks by abusing security defects, finds its way into any computers and multiplies itself until the whole network is infected.

- Viruses. A virus spreads and lives by attaching itself to a useful usually big software. It infects other programs by attaching copies of itself onto them.

- Trojans. Named after a classic tale about the same strategy, a trojan makes its way into its victim’s computer by fooling that it is a common program. Once it’s got there, not only will it work as it pretends to do, if any, but it will also do damages or harms to the infected computer and data.

Do you find that you keep on getting compromised by virus, worms, or trojans although you have the best security tools installed? Each one of the details in the following list is part of an all-inclusive and easy to apply security system.

You can defend both the system and your computer from almost all threats to your privacy and security, if you have a similar policy or just implement these points.

1. You should get all patches for your Windows OS and keep them always updated. All you need is a working internet connection and you will have an always updated Windows OS without any cost.

2. Have the best antivirus software installed. Consult software review for the best antivirus ranking to date. Nowadays, antivirus software solutions are sold at very affordable price; some with limited capablities are even free. Provide internet connection to let the antivirus update itself anytime, and let it run automatically when the computer starts. This can be done automatically by default with most programs.

3. Install a firewall and have it configured. A software or hardware based firewall is ok, as long as it is working and set properly. A router, in case you are using it, usually have a firewall already built in it, so that you just need to set the rules to make it work properly and effectively. Software firewalls are sold at affordable cost, even for free!

4. Don't install or run any program, but test them in different system or computer first to be safe. A virtual machine or a virtual computer can do this tricky job with no cost at all and act as a free virus protection.

5. Backup your files regularly, just in case. Best laid plans are those prepared for worst case. The cost may just be a few DVD's. With a spare large size harddisk, the cost is reduced to zero!

It's clear that it cost very low and even free if you want to protect yourself from threats.

I guess you have been in a situation where you are convinced to buy certain goods but regretted later when you’ve got home. I have. I usually categorize that kind of marketing as high pressure psychological selling, because the salesman usually applies high level of psychological pressure on the prospect to finally succeed in selling the goods. Trojans and worms are more and more into these practices of iplementing psychological pressure in order to compromise a victim. Such techniques implements but not limited to the exploitation of human basic psychologies: Curiosity, Greed, and Fear. How do we tell that a trojan or a worm virus is trying to get into our system using a psychological pressure? These are things to beare of to help us tell just prior to their attempts to compromise our system: 1. Is it pressing us to download and run some program, in the fear of getting the computer worse due to some infection of trojan or computer virus? If it is while it’s not at all the active running antivirus software we have installed, we can say that it is definitely a virus, malware, or even a worm. 2. Is it offering some software solution that looks like it’s too good to be true and free at the same time? At times, it can be just a marketing hype, but it’s a best practice to beware about the urge to download or agreeing on something it is offering. Downloading a program or just opening a page containing java script or flash application would be enough to get our computer compromised by a computer virus, malware, or trojan. 3. Are we aware of the brands (if any)? Is it a rather famous antivirus brand, or just some very popular one, but not an antivirus? Sometimes they ride with popular brands to fool the less cautious. Do you remember the “XP Antivirus 2008″ virus disguising Antivirus Software Downloads? Its high success rate really was boosted by the “XP” brand, riding on Windows XP’s brand. Lately, a brand new release of the virus is already spreading, one that we know as “XP Antivirus 2009″. 4. It’s a good practice to always check and recheck if the URL we type is not a fake or phising site. You have to do this if you wish not to unwantingly enter a phishing site, in which case is a much worse scenario compared to contracting a virus. A rogue site is an latest psychological scam in that it tricked visitors into thinking that it’s the right site they’re searching to visit. Everything they have on the page would in turn then be taken for granted by unsuspecting visitors. 5. If you are uncertain of those that I have mentioned, talk to a friend that knows more about this matter. There should be at the very least something certain about it, like a popular brand name of antivirus or computer security software solution, the exact URL or at least domain name of the target site, what should be classified into being too good to be true and what not. The success rate this way of contagion has is surprisingly high, assuming the wide availability of legitimate computer security software and antivirus or Internet Security Software available in the market. This is why I always urge everyone that asked for my opinion on computer security to continuously learn about it, even for just a small bit of knowledge. As only with knowledge even for just a little, can we actually pertain in the safe environment against malicious software.

Some spyware that will infect a computer is definitely an unwelcome presence that overstays its welcome and does some nasty damage to the host computer which of course is your computer and also to you, the end user.
