Computer viruses are software programs deliberately designed to interfere with computer operations, record, corrupt, or delete data, or spread themselves to other computers in the organisation and the network, often leading to disruption of work affecting your productivity at work. Computer viruses range from the mild annoyance to the downright destructive, and come in many different forms. The good news is that with an ounce of prevention and a little knowledge, you are less likely to fall victim to viruses and you can diminish their impact.


The following are the tips to help avoid or spreading of viruses:


Use an updating mechanism or system that would update all computers in the network automatically when new updates are available.

Set your computer OS and security applications (anti-virus, anti-spyware, firewalls) to update automatically.

If a computer is infected, isolate the infected computer from the network.

If malicious code exploit one of more of the network services, block access to that service until it is rectified.

Use a Internet firewall.

Never open an e-mail attachment from someone you don't know.


Avoid opening an e-mail attachment from someone you know, unless you know exactly what the attachment is. The sender may be unaware that it contains a virus.

Keep you network servers updated that host public services, e.g. HTTP, FTP and Email services.

When it comes to proper skin care, there are many important things to know. After all, you are going to be living in your skin for the rest of your life, so keep it looking and feeling healthy and beautiful. Your skin is the most noticeable part of your body, and the best way to achieve proper skin care is to start incorporating a few important steps into your daily routine. Simply by adding these few extra steps to your regular skin care routine, you will notice almost immediate results.

Cleanse

Cleansing is one of the most important steps, but before you choose a proper face cleanser you need to determine what your skin type is. The basic types are oily, normal, dry, or sensitive. If you are not sure which type you have, it isn’t hard to find out. All you do is wash your face and pat dry, making sure not to rub because this can tear the skin. Now take a few pieces of rice paper and press on different spots of your face. If your skin is oily, the paper will stick. If the paper falls right off, then your skin is dry. If it sticks a bit but then falls off, you most likely have a normal or combination skin type.

Now comes the hard part. You have to find a good cleanser that your skin is going to respond well to. This can be particularly difficult if you have sensitive skin, because many products will be too harsh for you to use. Even if you have oily skin, you want to avoid bar soaps, as they are much too rough on the skin, especially on the face where the skin is most delicate. One of the most important skin care rules of all is to not cleanse too often—typically washing once in the morning and once at night should be enough.

Exfoliate

Another critical part of skin care is exfoliation. Regularly exfoliating your face is especially important, because it will help get rid of dead skin cells and leave your skin looking healthy and smooth. Exfoliating is simple. All you need to do is lightly moisten your face, then, using a loofah, rub a dollop of exfoliating cleanser on your face. You can use sugar or any other grainy products as well. Rub in circular motions, avoiding scrubbing too hard under the eyes because the skin there is very thin. Continue rubbing for a few minutes, then rinse off your face with warm to cool water.

Moisture

Moisturizing is the next important step in any skin care routine, even if you have very oily skin. You need to use some type of moisturizer, especially after cleaning and exfoliating the face. Moisturizers work by sealing moisture into the skin, and it also ensures that the skin is smooth and supple. The best way to do this is by using your fingertips. Dot the moisturizing cream around the area of your face, and then gently massage the cream into your face, making sure to get around your T-zone area, which is down the nose and across the forehead. Make sure that while you are massaging the cream you are using alternating strokes and never over-moisturize, as this can cause your skin to look oily.

Proper skin care is critical to looking and feeling healthy and youthful, and by taking proper care of your skin now, you will be doing yourself a great justice in the future. Your skin will remain soft, smooth, and supple, even as you age.

Wireless Internet access can offer convenience and mobility. But there are steps you should take to protect your wireless network and the computers on it.


Use encryption to scramble communications over the network. If you have a choice, use Wi-Fi Protected Access (WPA) encryption as it is stronger than Wired Equivalent Privacy (WEP) encryption.

Use anti-virus and anti-spyware software, and a firewall.

Most wireless routers have a mechanism called identifier broadcasting. Turn it off so your computer won't send a signal to any device in the vicinity announcing its presence.

Change the identifier on your router from the default so a hacker can't use the manufacturer's default identifier to try to access your network.

Change your router's pre-set password for administration to something only you know. The longer the password, the tougher it is to crack.

Allow only specific computers to access your wireless network.

Turn off your wireless network when you know you won't use it.

Don't assume that public "hot spots" are secure. You may want to assume that other people can access any information you see or send over a public wireless network.

The Internet provides wealth of information on virtually anything. This also includes information or content that is seen to be unsuitable for internet user, especially kids and teenagers. The nature of contents ranges from that is violent, misleading, unverified, false and menacing. The law and regulations for web content varies from country to country, whereas the Internet platform is an open and global platform. Anyone can create a website and post content of any nature. It is easy to say that it’s up to the user to view or read the content but kids and teenagers may not be able to assess the suitability and may be influenced from viewing or reading such information.

As parents and adult, following are some of the tips for educating your children on handling website contents:

Ask your children to share their online experience, e.g. the website they have visited and the friends they have made. This is a good way of monitoring their online activity. It is important that parents include this in their daily conversations with them.

It is good to educate your children when they are young on online safety and more importantly the content they can find or come across. They will know their do’s and don’ts as they have been nurtured at their earlier years. Just like in real life, parents tell us, “look before you cross the road”. This advice becomes a natural habit over the years because our parents have said so.

Whenever your child go surf the internet, parents should occasionally sit together and explore the internet with them. Parents need to guide them to the suitable websites or perhaps, bookmark some sites for them.

Computers should be placed in the common areas of your home, e.g. living room. Parents will find it easier to monitor their children.

Parents should check all file sharing software such as P2P. They should only download or send legal files.

Inform your children if they feel uncomfortable about a website they have visited, they must tell you, so you could verify or block the website. To block in Internet Explorer, refer to the following instructions.
Steps to block websites in Internet Explorer 7:

In the Menu Bar click Tools -> Internet Options -> Content. In the Content Advisor box, click Enable.


Click the Approved Sites tab. Enter the address of the website.

Keep in mind - if you want to block the complete website put * in front. For example to block myspace completely, type *.myspace.com Click Never and then OK.


Click on the General tab and sure to select Users can see websites that have no ratings.


Enter a password you can remember easily with a hint.

Click OK to surf the Internet safely.


Parents should consider using content/filtering software to monitor their children’s online activity and access. There are some good web filtering software such as K9 Web Protection, NetDog Internet Filter, and SafeSquid.

Do some investigation on your children’s online activities by checking their cookie, cache files and history on their computer.

Set your web browser to “block pop-ups”. This eliminates the possibility of children clicking on pop-ups that may lead to inappropriate website or download viruses.

Teenagers are creative, experimental and eager to explore new things. Parents should practice the same to study the current trends and issues. Parents should bookmark good websites that talk about internet safety and share this with their children and friends.

With the Internet, any form of information can be expressed without any moderation or restriction. People can post and write articles to express their feelings of anger, hate, frustration or prejudice.

As a responsible citizen and Internet user, certain precautions should be taken to ensure so that you do not land in the hands of the law.

You should not share information that is highly sensitive or degrading on public domains or websites that is accessed by many people. If possible avoid all together.

Careful when you receive any emails with hate speeches or any form of recorded information that may be highly sensitive. You should delete and do not forward them.

Don’t believe any of information with malicious content posted on the Internet or blogs. It is advised to use your sound judgment to verify the information stated as it may not be true at all. It may only to provoke us to hate certain individual or organization without a clear proof.

Install content filtering software that can block sites which you may not want your children to access, e.g Content Advisor in IE7.

Educate your child on the difference between valid, true and false information. Tell them to seek your advice if they are not sure.
