Computer Virus and Security Protection Tips

The internet has its fair share of threats and dangers that could harm your PC and access your personal and confidential information without your permission. Computer security entails both detection and prevention from such people and programs. "Prevention" would help in keeping you safe from all such malicious attempts whereas "detection" would inform you whether someone attempted to access/harm your system, either successfully or unsuccessfully and what harm they may have caused.

Why bother about your computer's security anyway? Well, nowadays computers are used for almost everything from shopping to banking and from having casual conversations through internet chat to investing. Yes, much of your information may not be that confidential but you still won't want someone sending forged emails on your behalf or reading your personal or official documentation, like financial statements and bank account information. On a more serious note, an intruder or hacker/cracker may gain access to your computer to launch attacks on other computer systems. With access to your computer they are able to hide their true location while they launch attacks on high profile computer systems, like those of banks and other financial institutions.

Computer hackers / crackers are always looking for weaknesses or holes in the system. Developers are not always able to run comprehensive tests on their softwares because of its ever growing complexity. Later on when these holes are brought to the developer's notice, they create patches to address the problem. So, the number one tip to all computer users is to make sure you obtain and install the patches and security fixes regularly. Some software like chat programs actually allow other users to execute commands on your system which could open the window to all kinds of harmful programs. Therefore there is a need to be more careful when using chat programs of various kinds.

Install a firewall. Hackers/crackers are constantly scanning for known holes or vulnerabilities in the system. Software or hardware based firewalls can provide good protection from such attacks. Having said that, no firewall is capable enough to keep out all threats, therefore having a fire wall is not quite enough.

Use Antivirus software on each PC that connecting to the internet but an anti virus software that is not updated may do little or no good. Some antivirus software comes with automatic update options - these are thoroughly recommended.

Disable JavaScript, Active X and Java if possible. By disabling these scripting languages you will keep your system safe from malicious scripts. By disabling these options you may degrade the functionality of some websites. For More information on disabling scripting languages please visit http://www.cert.org/tech_tips/malicious_code_FAQ.html.

It is also thoroughly recommended to disable scripting features in email programs as many email programs use the same code as web browsers.

Be careful not to open email attachments even if you are familiar with the source of the attachment. The only reason the Melissa virus spread so far and so rapidly was because it originated from a familiar address. Before opening an attachment, make sure your virus definitions are up-to-date, save the file to your hard disk, scan the file using your anti virus software and then open the file. If possible, even disconnect from the internet before you open the file.

Don't run a program that's come from an un-authorized or un-known source. Don't also send these programs to your colleagues and friends as it may contain a Trojan horse (these programs are used to enter into the system and trick the user into installing various programs which allow hackers and intruders access to your system).

Turn off your computer when it is not being used. A turned off system or a system that is completely disconnected from the network is safe from all intruders.

Make a bootable disk which will come in handy if your computer has suffered an intrusion or a hard disk failure. The bootable disk may help your computer recover from such an event but remember, the bootable needs to be created prior to any security breach or malfunction.

Make a back up of all important files on a removable storage device like a CD or DVD and keep the storage device away from the computer. In order to safe space, you may also choose to ZIP your data (compress your data) using a compression software while making a backup.

Computer Defense System

Computer security is very important today. Without a great computer defense system, if you go online, you leave yourself open to all kinds of attacks both minor and very serious. Today all business and commerce is conducted by way of the computer. Additionally, once a transaction is completed, it is sent over the Internet to another computer where the transaction is verified and completed. It is very important to be aware of the steps that you need to take before you connect to the Internet to secure your computer. Those who wish to compromise systems are becoming more cleaver in their approaches everyday. It also seems with technology changing everyday, it is harder and harder to keep up.

A good computer defense system first means making sure that on a fresh install of any operating system, Apple OS included, all software updates are downloaded and any security updates are applied. In windows, set your security update options to at least "notify" you of updates even if you don't want to download them automatically. It is also most prudent to make sure all critical updates are downloaded and applied as soon as they become available. Microsoft Windows makes this easy with the Windows Update feature. Similarly there is a feature called software update in the Finder under the "Apple Menu" called software update. It is essential that you do this regularly. If you do not have options set to notify you immediately of updates, check for them a minimum of two to three times a month.

Another Part of your computer Defense System is your anti-virus software. In recent years their has been a tendency for the best know names in the anti-virus business to bloat their product with more and more features that many users will not use or use very sparingly. This taxes computer resources and slows down your computer because it is trying to do more and more background processes. There are many retail packages out there, but they are not all created equal. Also, be aware that program definition files (that tell the program about what viruses may exist on your computer) often expires at the end of a year meaning you will have to renew your anti-virus definition subscription in order to continue to receive updates. An alternative is a free antiviral software solution that provides updates for free. One of the best is by a company called Grisoft. It is called AVG. While I cannot put a link here, if you type "AVG Free" into Google, the link to the download page will be on the top of the list.

For your computer to be running properly, you also need to enable any firewalls on your system. For example, in the Control Panel of recent Windows OS versions (like XP or Vista), you will find a security section (Tab or Icon). Once there, make sure the Windows firewall is enabled. However limit the installation of firewall software because not only can this cause program conflicts and slow down your system, cryptic warnings about a possible intrusion will not benefit you and scare an inexperienced user. Instead install a router or get someone to do it for you. Even if you only have one computer because a router is a physical firewall blocking potentially harmful Internet traffic for you. Also much lower prices on computers now means having multiple computers is affordable. A router allows multiple computers to share a single Internet connection.

Another important consideration is not to install toolbars unless from a recognized and trusted source. A good computer defense system recognizes that many of these installations are actually malware in disguise that can do things in the background that may harm and compromise your system. Also, do not download email attachments. This is one of the major ways that a virus or other malicious or self-executing code actually gets on your system in the first place. You need to exercise do vigilance when on the Internet and click with care. Also make sure that things like Active X controls are not automatically set to run on a page. (Unless on a trusted site that requires it.) Additionally, think seriously about changing the browser you use to surf the Internet with. Type "Get Firefox" in Google. Firefox is a better browsing alternative than its man competitor and it is more secure because it is more of a basic browser that does not automatically execute advanced functions that can lead to viruses, malware, Trojan horses and other malicious code that can seriously harm your computer.

A good computer defense system requires more than what has just been detailed, but these steps are important and will go along way toward a more secure and safe computer system. For even more extensive information; look to the end of this article for links showing you where you can go next.

Is There Still a Future For Anti-Virus Software?

Look, if you told me that people should stop wasting their money on stand-alone anti-virus applications then I could have agreed with you to some point. The only thing that's outdated is the term "anti-virus". Strictly speaking, the main online threat is no longer called a virus, a more appropriate term should be "malware" and it is time we started to adapt to this new term. Online threats consist of viruses, spyware, key-loggers and trojans, all residing under the common term of malware.

I understand that the term "anti-virus" is a heavily marketed term and when you mention the term "anti-virus" to computer illiterate and inexperienced users they know exactly what you are talking about, but when you talk about malware they often give you that glossy stare, you know, the kind of stare that screams: "What the hell are you talking about!" Most anti-virus applications now offer protection against spyware and other malware related threats as well, so it is really silly to keep calling them anti-virus applications, they are in essence anti-malware applications.

Scraping your anti-virus solution is reckless and plain stupid. It's just as good as saying we should stop patching the security flaws in software, leave them un-patched because the threats, exploiting these flaws, are evolving way too fast. Should we stop installing security systems in our homes because new, more advanced burglars are born each day? If you can protect your system against known threats why not do it?

It is true, malware evolves much faster than the anti-malware solutions, but known malware gets recycled on the web over and over again. Protecting yourself against a known variant means you can't be attacked by it again and believe me it is not uncommon to be attacked by the same variant more than once. This means anti-virus software still plays a vital role in your protection against malware, it also means that anti-virus software developers are still detecting new threats at a very high rate. New variants may infect quite a lot of computers before they get detected, but once the anti-virus vendors release an updated signature file to all their users, they are at least constraining the spread of the malware and preventing uninfected users from getting infected.

Scraping anti-virus solutions means systems are left unprotected, meaning that they are left infected, thus making a contribution to the processing power of bot networks like Storm. At least an infected system can be cleaned once a new variant has been detected, therefore you are pro-actively taking a bot network down bit by bit and making it harder for the malware to spread any further. Remember, an infected machine becomes a distributor for new variants of the malware. Killing a known variant means you are preventing it from mutating and spreading any further.

Improve the technology, don't scrap it. Yes, definition based protection is nearing its end, but anti-malware solutions are moving towards behaviour based detection. It is suicidal to scrap anti-malware solutions completely just because of the fast evolution of new threats. The argument that the value of anti-virus software is declining is a bunch of hogwash. Big corporations should stop putting reckless ideas into the minds of ordinary users, they should stop the throw-away-your-anti-virus-program-and-buy-our-software kind of marketing. The Internet is dangerous enough as it is, so don't go encouraging people to throw a way their anti-malware applications, not even in today's world of advanced malware attacks. Anti-malware applications are often the only line of defence that's available to novice Internet users.

How to Detect a Scam

I am sure that some of you have been a victim of Internet Scam. How do you detect a scam? I can tell you from my personal experience how to detect a scam and what needs to be done about it. Internet scams comes in variety of ways. If you type in the keywords for "work at home, surveys, mystery shoppers, online business, and processing credit cards", you will see a dozen of website that literally beg for your undivided attention. Their website looks as though it is so easy to make money. They have testimonials of people making big bucks. They say you can make $500 to $1000 per day part time. It says that you can start in 10 minutes after purchasing their service. What service you may ask after purchasing their service. The only thing you see is a bunch of websites that say that you can make money being a mystery shopper, filing out surveys, and processing credit cards.

Most of the scam sights are not secured. It does not have a padlock or https. Therefore, anyone can see your personal information. Needless to say, they ask everything about you: What is your income, your age, address, and telephone number. Little did I know that I would get junk mails and phone calls from telemarketers wanting to allure you to their business. What surprised me is that they sell your information to third parties. I was charged for some website service on my Verizon telephone bill.

Please be careful of websites with an ending of .org. It's supposed to be a non profit organization but some deceitful people use it to fool consumer thinking that their content can be trusted. Surveys and processing credit cards are scams. If you have to pay $1.97 for a trial period and be charged $37.95 monthly thereafter, please don't do it. Most likely, they will add charges you don't recognize and give you a hard time with refunds. I ended up putting a dispute with my credit card and bank account. I had a terrible experience with work at home companies found by googling the keyword: "best work at home opportunity, how to make money part time". If you have trouble with refunds, you can file a complain with the better business bureau or the FBI.

They say when it rains it always shine. Here is the good news. I found a genuine, remarkable, authentic, Internet marketing course that takes you by the hand and teaches you what you should not do and what you should do. This service is incredible because it reveals the secret of being successful. I can't believe that Mike Andrews is giving away such valuable information that most gurus would keep to themselves. He has tons of tutorials, videos, resources, and great tools provided to members. I have never seen such a wonderful sight for learning how to start your own business. He has pre-made websites with your own id for you to promote. I get very excited when I talk about the materials he offers. What's more amazing is that you can try out the course for 80 days with an unconditional money back guarantee for only $87.00. This is a bargain. This is nothing compared to what you have to pay for a one day seminar which is around $150.00. Just by learning his tutorial, I learned how to get traffic to my website in different forms. You have everything to gain and nothing to loose. For more information, please visit my blog at:
