Antivirus Firewall Software Buying Guide

Before you set out paying for your subscription of your antivirus firewall software choice, you need to concern yourself with some important considerations first. It’s possible that the antivirus program may be top-of-the-line, but if it doesn’t suit your conditions, it’s practically of no use to you.

What are the foremost important things that you need to look into before purchasing your antivirus firewall software? There are at least three of such considerations. Each one is discussed briefly in this article.

The first thing to consider is whether your computer’s hardware contains the minimum requirements to run the security program. Different antivirus software applications require different hardware requirements. Some programs are actually memory hogs—they just eat up a lot of your computer’s physical memory. Other programs are truly processor hogs—they use up much of your processor power either while at an idle state or when actively scanning your drive. It is important that your computer at least meets the minimum hardware requirements of your security program. Ideally, your hardware should exceed the minimum required.

The second important thing to consider is whether your operating system is supported by your chosen antivirus application. If you’re running Linux variants or Unix, you would hardly need antivirus protection. But, if you’re using a version of Microsoft Windows, you would like to check for compatibility. Although most antivirus applications support all of the recent versions of Windows, you still would like to double check. You wouldn’t want to pay for an antivirus software program meant to run only on Windows XP or a program designed for optimal use only with Windows 7.

The third important thing you must consider is your security needs. Do you need only antivirus protection? Or do you also need a software firewall solution that monitors all incoming and outgoing network data? What about spyware and adware protection? Some programs are exclusively for antivirus scanning and removal, while others feature an all-in-one solution. If antivirus protection is your primary need, you’d probably want to subscribe to a stand-alone antivirus program and just use free anti-spyware, anti-adware, and firewall programs. Stand-alone programs are generally much cheaper than all-in-one suites. Also, stand-alone programs tend to be much more efficient than bundled security suites as the stand-alone program focuses on doing only the tasks that it was designed to do. Though, this is not the case in all security protection software programs.

There are other important factors that you need to consider when you shop for an antivirus protection program. This article discusses only three of the most important. Keep these factors in mind when you start looking for your antivirus firewall software application so that you will be guided accordingly.

ATX Power Supply Repair And Troubleshooting

Customer ATX power supply came in with the complaint of intermittent no power. When testing it with power on, I could see that the fan is not rotating. Not only that, some filter capacitors also became bulge because of the heat accumulated inside the power supply. The failure of the fan would not suck out the heat generated by the components especially the switch mode power transformer.

If you switch off a working power supply and power removed, touch the power transformer, you could feel it is quite warm. Another heat source would be the heat sink where the output diodes attached to it. Diodes run a little bit hotter in filter circuit than diodes in other circuits due to the high current present at the secondary output line.

As for the malfunction fan, you actually could use a Philips oil based contact cleaner to service the fan. The grease inside the fan would run dry after serving for sometimes and eventually stop rotating. Remove the back plastic cap of the fan and spray it with the contact cleaner and you would be surprised the fan could actually regain back its glory. It will actually work just like a new fan. If it still doesn’t rotate, the best choice is to replace with a new fan. If you have the power supply that lying down at your work place then you could salvage the fan and install it.

From the photo at my website you also could see those decayed glue that stick besides the components. Manufacturers purposely used some kind of glue to apply on the components where they think those components will shake or comes out when there is vibration or during shipping. After the equipment work for a long time and the heat generated inside the equipment will turn the glue into conductive and sometimes would even corrode the pins of the components and eventually cause the equipment to stop working.

Scrap it off with your test pen and use Thinner solution to clean the printed circuit board. After replacing the capacitors, removed the decayed glue and service the fan, the Atx power supply again given a new life to faithfully serve the computer.

Some ATX power supply would take you a longer time to troubleshoot because of ‘too many’ components on the board. The most frustrated part is that you could not get the spare parts especially the power ic. Even if you could locate one, the price would be sky high and if this happen, I will usually get the customer to buy a new unit since nowadays the price of a new one are quite cheap.

Electro-Mechanical Assemblies In The Military – A Beginner’s Guide

When it comes to working with clients like the military, quality and reliability in all areas of manufacturing is crucial because their applications are too critical to fail. This is most certainly the case with electro-mechanical assemblies. After all, the military aims at running as smoothly as possible, and in order to do this, the right materials in their computing & mechanical systems are paramount to their success.

In order to understand electro-mechanical assemblies in terms of military applications, it is perhaps best to look at the construction & use of these assemblies in terms of 1) what they are; 2) the ability to deliver the necessary materials; 3) having the proper certification; and 4) the ability to deliver a finished product on time.

In essence, a device with an electrical & mechanical component can be referred to as electro-mechanical. Think moving parts powered by electricity or that have electricity running through them. There are an endless number of devices that can qualify under this definition, but typically you are referring to things related to computers or that are operated by computers. Items such as fan tray assemblies, box build assemblies, and switch & sensor assemblies all constitute electro-mechanical assemblies.

With respect to the military, assemblies are put through to the test because they will face tougher field conditions. A typical assembly might do the job, but as with most things military, there’s a need for electro-mechanical assemblies to go a bit further. Again, you’re talking about an industry that has critical missions that depend on all equipment to be working at all times. Failure is not an option. As the military contracts this type of work out, they, too, need to be sure that the manufacturer they plan on working with can actually produce what they need.

It’s also important that the prospective manufacturer the military plans on working with for its electro-mechanical assembly needs has skilled employees that are fully trained & are up-to-date with current regulations & industry standards. Moreover, it’s important to know what type of industry credentials a manufacturer carries. Certifications should include IPC/WHMA/UL certificates, as well as ITAR compliance, and they should have qualification in MIL Specifications.

Finally, the military depends on a strict adherence to lead times for delivery of goods. While the budgetary concerns a general commercial industry may face are different for a government agency, there is still a need to respect said agency’s schedule. Losing track of when materials will be delivered can be of grave consequence to the military. Both parties need to be in full communication at all junctures of the manufacturing process to be sure a contracted production date will be kept.

Electro-mechanical assemblies can be found in just about any industry you can think of that uses a combination of electrical and/or mechanical components. Military assembly needs take on a more pronounced significance, requiring efficiency in the manufacturing & production process, rigorous testing, and strict standards in both industry credentials & delivery lead times.
