how to protect your computer from viruses, worms, trojans

If you are using Windows operating system (OS), always keep your windows up-to-date and install the latest service pack. If you are using Windows Vista, Windows XP, Windows 2000 Service Pack (SP3) or later, or Windows Millenium Edition (Me), Automatic Updates delivers updates to your computer automatically, so that’s the easiest and most reliable way to make sure that you get new security and other high-priority updates as soon as they become available. If you use Windows 2000 SP2 or earlier, Windows 98, Windows 95, or Windows NT Workstation 4 you can go to Windows Update for the latest security updates.

Always download the latest antispyware and antivirus updates, and then scan your computer right away. Use a firewall and keep your operating system updated with the latest security updates, and use both antivirus and antispyware programs. The newer version of security software called internet security suite contains firewall, antivirus and antispyware: 3-in-1. Examples: Trend Micro Internet Security, AVG Internet Security, kaspersky internet security, Panda internet security.

Social networking safety tips for teens and children

Observe and think about how different social networking sites work before deciding to join a site. Some sites will allow only a defined community of users to access posted content; others allow anyone and everyone to view postings.

Take  some control over the information you post in social networking sites. You may want to restrict access to your page to a select group of people, for example, your friends from school, your club, your team, your community groups, or your family.

Keep your private information to yourself. Don’t post your full name, Social Security number (SSN), address, phone number, or bank and credit card account numbers in social networking sites. Be cautious about posting information that could be used to identify you or locate you offline. This could include the name of your school, sports team, clubs, and where you work or hang out.

Make sure your social networking’s screen name doesn’t say too much about you. Don’t use your name, your age, or your hometown. Even if you think your screen name makes you anonymous, it doesn’t take a genius to combine clues to figure out who you are and where you can be found.

Post only information that you are comfortable with others seeing and knowing about you in social networking sites. Take note that many people can see your page, including your parents, your teachers, the college you might want to apply to next year, or the job you might want to apply for in four years.

Remember that once you post information online in social networking sites, you can’t take it back. Even if you delete the information from a site, older versions exist on other people’s computers or search engine caches.

Consider not posting your photo in social networking sites. It can be altered and broadcast in ways you may not be happy about. If you do post one, ask yourself whether it’s one your mom would display in the living room.

Flirting with strangers online in social networking sites could have serious consequences. This is due to the fact that some people lie about who they really are, you never really know who you’re dealing with.

Be wary if a new online friend from social networking sites wants to meet you in person. Before you decide to meet someone, do your own research: Ask whether any of your friends know the person, and see what background you can dig up through online search engines. If you decide to meet them, be smart about it: Meet in a public place, during the day, with friends you trust. Tell an adult or a responsible sibling where you’re going, and when you expect to be back.

Trust your gut if you have suspicions. If you feel threatened by someone or uncomfortable because of something online, tell an adult you trust and report it to the police and the social networking sites. You could end up preventing someone else from becoming a victim.

What is VPS hosting?

A virtual private server (VPS) is also known as Virtual Dedicated Server (VDS). It’s a method of partitioning a physical server computer into multiple servers. Each has the appearance and capabilities of running on its own dedicated machine. Each virtual server can run its own full-fledged operating system, and each server can be independently rebooted.

Why we need VPS hosting?
It’s because VPS hosting allow us to enjoy the benefits of “virtual” standalone server without the needs of investment on physical hardware and operating system software.

Let’s visualize a physical server that is separated into several secure virtual private servers (VPSs). Then, the users will manage each via remote administrator access which executes exactly like a stand-alone server, ensuring guaranteed resources and preventing applications from conflicting. Each VPSs can be rebooted independently from other VPSs and have users, IP addresses, processes, system libraries and configuration files.

Benefits choosing VPS hosting

Security
Note that VPS hosting is isolated from other VPS accounts and it has its own set of processes and resource management, thus behaving exactly like an independent stand-alone server. Since user’s file system is not accessible or viewable by other VPS accounts, it give user higher level of security.

Complete Control
User has total control over his/her server configuration and access to root account. The user can configure all of the site management tasks using its user friendly, simple web interface.

Top-Class Performance
Since the resources allocated for VPS hosting is solely for its own usage, thus allowing it to have more power, more customization, more flexibility, and more functionality compared to normal shared hosting plans.

VPS hosting is recommended for corporate website, blog, mail server, forum, portal, online store, online storage, etc.
