The continual penning and circulating of computer viruses and of panic about them grants the sellers of commercial anti-virus software a financial interest in the ongoing existence of viruses. A few suppose that anti-virus companies have fiscal links to virus authors, to generate their own marketplace, though there’s actually no evidence that we know of. Some of the anti-virus software can reduce computer performance considerably. Users can disable the anti-virus protection to get over the performance loss, therefore raising the danger of infection.

For the greatest protection the antivirus software requires to be enabled at all times-often at the cost of more sluggish performance. It’s also all important to recognise that an individual shouldn’t have more than one antivirus software package set up on an individual computer at any given time. This may severely cripple your computer and cause additional damage. It is essential to temporarily disable computer virus security while you set up major updates such as Windows Service Packs or updating graphics card drivers. Having antivirus protection functioning at the same time as installation of a major update might keep the update from installing correctly or even installing at all.

Once you do make up your mind to buy antivirus software, the arrangement might include a clause that your subscription will be automatically renewed, and your credit card automatically charged at the time you’re supposed to renew without you authorising it. For instance, Mcafee expects you to subscribe at least sixty days prior to the expiration of your present subscription, Whenever that’s the case, the subscriber could contest the charges with the credit card issuer, but this course of action is probably to be of no help to you if as a matter of fact the subscriber had cleared such a “uninterrupted payment authority”.

A few anti-virus programs are in reality malware masquerading as anti-virus software. It’s to your advantage to ascertain that the software package which you’re downloading is really a genuine antivirus program. A few commercial antivirus software programs hold adware, For instance, the home/small business edition of a CA Anti-Virus 2008 exhibits an advertisement for CA products whenever the desktop is unlocked after a period of time while the computing machine isn’t active. It will be no surprise when computer viruses that plague the desktop and the laptop computer world rapidly migrate to mobile devices. Increasingly sellers in this space are providing solutions to combat this.

Antivirus programs arrive in a lot of various forms and range from affordable to very costly but believe me, without an anti-virus program you’re going to finish up worse off money-wise in the end because of the expenses of reviving or replacing your computer. You are able to locate a lot of these types of programs for your home computing machine or office computer right here on the World Wide Web or in some computer shop in your region. Good luck with keeping your computer up and running correctly and if you don’t already have an antivirus program for your computing system, please look at opting to buy yourself one without delay.

Many people looking about antivirus reviews as they are many products that compete each other to be the best. Since internet era spreading of a virus become faster and infected PC become much more day after day. So to help these kind a people we made some antivirus reviews so you can choose what best for you.

Well, the basic step for protecting your system is to install an anti-virus that works for your computer system. What do I mean by an antivirus that works for you? Well, everyone visits a different set of websites everyday, has a different system configuration, does different things with his/her PC and keeping all that in mind you need to decide which one works for you. This, I say from personal experience.

If you are yet not sure whether you even need an antivirus : Check this out (Scroll down)

The thing to note is that not every Antivirus is suitable for every system and hence you may need to experiment a bit before you find the perfect one.

I am not going to write paragraphs on this, just the ‘Good’ and the ‘Bad’. ASk if you have doubt.

Note: The software are listed in an alphabetical order and not preferential.

1. AVG Antivirus:

Good: Only antivirus thats free to use and ranks among the best. Eeffective, easy to use and compatible with almost every computer. Try it out ? Sure, its free !

Bad: No tech support to go to if it falters as its free. May skip some of the viruses. Keep a check.

2. Bit Defender:

Good : Has earned good reviews based on its superior performance and cost effectiveness. Pocket-friendly.

Bad : The interface is not that friendly and you may need to dig a lot deeper to find the in-depth reports of your scanned files (which lie in the Antivirus and Updates tabs).

3. Esset NOD32:

Good: An antivirus that is known for its quite simple and user friendly interface, NOD 32 is very simple to use and is usually recommended for beginners. The other advantages of the software include its high detection ratio, no software conflicts and the fact that it won’t drain your system. If you are looking for a fast antivirus, nothing beats the NOD32.

Bad: Slightly on the heavier side in terms of the price.

Beginners Guide – Secure Network

Secure network is vitally important for most network systems. Whilst email viruses and denial-of-service attacks (DoS attack) may cause us headaches on our home systems, for businesses, these sorts of attacks can cripple a network for days – costing businesses hundreds of millions each year in lost revenue. Not to mention corporate legitimate to clients.

Creating secure network to prevent this type of malicious attack is usually of paramount importance for network administrators, and while most invest heavily in some forms of security measures there is often vulnerabilities inadvertently left exposed. As we always heard that security is as secure as the weakest link.

Firewalls are the best place to begin when you are trying to develop a secure network. A firewall can be implemented in either hardware or software, or most commonly a combination of both. Firewalls are used to prevent unauthorized users from accessing private networks connected to the Internet, especially local intranets. All traffic entering or leaving the intranet pass through the firewall, which examines each message and blocks those that do not meet the specified criteria. If the packet do not meet security criteria then the system will not allowed those packets entering network system.

Anti-virus software works in two ways. Firstly it acts similarly to a firewall by blocking anything that is identified in its database as possibly malicious (viruses, Trojans, spyware etc). Secondly Anti-virus software is used to detect, and remove existing malware on a network systems or workstation.

One of the most over-looked aspects of secure network is time synchronization. Network administrators either fail to realise the importance of synchronization between all devices on a network or the system simply don’t work. Failing to synchronize a network is often a common security issue. Not only can malicious users take advantage of computers running at different times but if a network is struck by an attack, identifying and rectifying the problem can be near impossible if every device is running on a different time.

Even when a network administrator is aware of the importance of time synchronization they often make a common security mistake when attempting to synchronize their network. Instead of investing in a dedicated time server that receives a secure source of UTC (Coordinated Universal Time) externally from their network using atomic clock sources like GPS, some network administrators opt to use a shortcut and use a source of Internet time.

There are two major security issues in using the Internet as a time server. Firstly, to allow the time code through the network a UDP port (123) has to be left open in the firewall. This can be taken advantage of by malicious users who can use this open port as an entrance to the network system. Secondly, the inbuilt security measure used by the time protocol NTP, known as authentication, doesn’t work across the Internet which means that NTP has no guarantee the time signal is coming from where it is supposed to.

To ensure that you have a secure network, isn’t it time you invested in an external dedicated NTP time server?
