New computer worm could hit on April Fools’ Day. Are you ready?Internet and Computer security professionals are predicting that there is another computer worm that will be pushed into public on April Fools Day.
The new virus is called “Conficker C”, and it’s similar to another worm that threatened computers back in January.
It may have been built with the same characteristics as a Trojan. Meaning, it will infect a computer and it will hide itself inside the O/S. The worm is programmed to take over these computers on April first.
It’s anybody’s guess what happens then. Experts think it may delete all the files on a person’s computer, or turn the computer into a zombie, to send spam or attack other websites in an effort to shut those sites down.
There’s also a theory the worm may be a spam program to get people to buy phony products.
The worm keeps computers from downloading automatic updates from Windows, so one quick way to see if your computer is infected is to see if you have gotten automatic updates from Windows in March.
If you have the updates, your computer is probably fine. If you’re not infected, you can take action to make sure you stay safe.
- Don’t open any suspicious links, emails or e-cards.
- Keep your anti-virus protection up-to-date.
- Take advantage of FREE downloadable spyware detection programs.
If you have an Apple computer that runs Windows software, check for updates as well to make sure you’re protected.

Whether you are setting up a new business or office or making huge changes to your growing business empire, a new plan to develop a solid IT network infrastructure is required as the individual units that make up your business are crucial for smooth operation of any business. It is not just how each computer unit works, but how they all work together and how they are connected. This is what the network governs and planning it right will ensure optimal and safe performance.
Below are a few tips that will help you plan your new IT network infrastructure:
Decide what Network Topology fits your Needs and Building Layout
There are many different ways in setting up a network for IT usage. Each network has their own advantages and disadvantages and some others can be more advantageous in certain room or building layouts. Analyze these factors and weigh them in with the kind of features you need in a network. Common networks use the star topology including the IT businesses that adopt structured cabling systems. Who knows? You might even need to incorporate wireless capabilities in the network when things get messy. Draw diagrams or use CAD software to help get the idea of the network to avoid backtracking.
Fulfil the Requirements of the Network
Once you have decided on which network to use, you will need to identify and fulfil the requirements of the network for it to function correctly. This includes the basics of networking like IP assignments and answers to simple questions like, whether or not the network will use public or private IP addresses, how IP addresses will be assigned to the client, units and if multiple subnets are required. The best way to plan for this step is to use network simulator software.
Optimizing the Network Performance
After you did all the network IP assignments and find that everything is working, you can proceed to optimizing the performance for faster operations and more reliable computing as a whole. If you chose the right topology, you may need to do very little here. This involves basic TCP/IP tweaking such as setting the Maximum Transmission Units, Maximum Segment Sizes and other packet settings. The objective is to cater to your bandwidth limitations and squeeze as much performance on your network as possible.
Take Security into Consideration
Now that you planned how optimized your network is, you should then put security into the picture. Normally security measures sacrifice network performance, but if you optimized the network to the best as possible, there should be room for a little bit of degradation to give way to security. This should be taken very seriously especially on the larger networks that have lots of sensitive data. Not only security from hackers and viruses, but also stable measures to avoid data loss and corruption. You need to make sure your network runs stable and that minimal problems arise to avoid time loss on troubleshooting.
A well-planned network can immediately go to work after you start executing your plans. Don’t forget to test everything and make sure the network runs properly so you can switch to the live environment and launch your new IT network infrastructure.

IT professionals have always had to deal with the increasing difficulty that comes with keeping track of an increasing number of computer systems as a business grows. This type of need is commonly referred to as network inventory or PC auditing. Long ago, if one needed hardware and software inventory across a network, it meant physically visiting each computer on that network and documenting everything in a spreadsheet by hand. Thankfully, over the years, software and operating systems have greatly improved, making network inventory easier. NEWT Professional is one such software product created to reduce the work involved in asset management. Developed since 2003, NEWT has evolved into a high speed PC inventory tool, capable of scanning every 100 computers in less than 5 minutes, saving time and money for organizations of all sizes.
In the world of network management products, there are several methods used to inventory computers. Two main divisions are tools which use an agent and those that are agent-less. Many agent-less tools can be excruciatingly slow and/or have numerous issues with computer and security configuration, such as WMI (Windows Management Interface), thus they still require visiting those computers to “fix” problems before they can be audited. This can be very frustrating. Using an agent can circumvent these problems, but often requires hours or days of lengthy deployment.
The wizards at Komodo Labs dedicated a solid 6 month period to developing a solution to these network administration problems, resulting in their newest version 2.5. NEWT Professional now only requires read/write access to the ADMIN$ (pronounced “admin dollar” or administrator) share, which is exposed by default to all network administrators by Windows NT, 2000, XP, Vista and Windows 7. This allows IT professionals to obtain the same information in just minutes that previously took hours or even days. Not only has scan speed increased, but network bandwidth was greatly reduced, making it possible to perform network inventory over slow connections such as WANs (Wide Area Networks) with little impact on traffic.
NEWT Professional is useful for just about any network where a total network inventory is needed, and many MSP (Managed Service Providers) and consultants use NEWT Pro to effectively gather configuration information for their clients. It detects all the normal hardware and software inventory information, including CPU info, system serial numbers, OS Product Keys, etc., but also goes a step further, gathering CPU, system and hard drive temperature, USB type (1.x or 2.0), correct hard drive type (IDE vs. SATA) & serial number, monitor type (LCD/CRT), detailed RAM Slot info and many others.
After performing a network audit, data is available in an easy-to-read spreadsheet-like view, with options of saving to NEWT’s proprietary format, exporting to Excel, HTML, text or even a fully relational MS Access (MDB) database.
When it comes to fast network inventory, NEWT Professional meets the needs of network professionals everywhere, all without breaking the bank.

There are a variety of ways to help get rid of spyware when using Internet Explorer. Follow these tips to make your pc less susceptible to spyware infection:
- Don’t let your browser automatically run installation programs that don’t have a valid “signature”. This setting can help to make you aware of the source (software developer) where the download was created, and you’ll have to decide for yourself if you can trust the source. Failure to protect yourself from invalid installation programs can leave you susceptible to “drive-by downloads”, programs that try to install themselves as you’re browsing the internet. To inhibit this from happening in Internet Explorer (the most common browser used today) go to Tools, Internet Options, go to the Advanced tab and scroll down to the “Security” area. Make sure the checkbox next to “Allow software to run or install even if the signature is invalid” is not checked, and “Check for signatures on downloaded programs” is checked.
- To further protect your browser from being an avenue for spyware installation, keep your security settings to “Medium” or “High” for the Internet zone. In Internet Explorer, go to Tools, Options, go to the Security Tab and click on the Internet zone, then click on Custom Level and you’ll see a number of individual security settings. If you really know what you’re doing you can change each setting individually, but for most people check the Reset Custom Settings dropdown and make sure it’s set to Medium or High. Ensuring this setting can help to eliminate adware and spyware.
- Create a pc login account that doesn’t have administrative rights, and be signed into your computer under this account when you want to browse the internet. Most people give themselves administrative rights so they can install software whenever they feel like it. This can allow spyware and adware programs to install themselves and alter your registry or browser settings. Logging into your account with “user” rights and not “administrative” rights can help you eliminate adware and spyware installation attempts. Refer to Microsoft’s documentation for your version of Windows to find out how to create a new user account.
- Avoid installing special “toolbars” on your browser. Toolbars and other browser “add-in” software can track and relay your browsing activity to unknown individuals over the internet. Many of these programs allow advertisers to target you with specific types of ads based on the kinds of websites you’re going to. Personally I’d rather not let them know that much about me.
- Use a good anti-spyware and adware detection program to get rid of spyware. This goes without saying. You may think you’re protected by your anti-virus software but most programs don’t adequately address spyware and adware. Consider protecting yourself with a program that specializes in this type of protection.
Don’t expose your personal information to unknown individuals through spyware and adware infections. Following these 5 tips can reduce your pc’s susceptibility to spyware infection and improve your internet browsing experience.
