Computer virus is an infection which spreads automatically in the files and folders if not eradicated. Not only the single machine but it can also spread itself over the network and over the removable media. Most of the Anti-Virus applications that are available these days scan for a fix pattern of bits in any file and decide it to be virus infected or not. This fix pattern is identified by the virus definitions which are regularly downloaded and installed by the Anti-Virus application. This set of Bits is also known as the signature and this is what is matched with the virus definitions installed. There are some Virus available which have their own way of handling such signatures. They change the signature on every hop and so it becomes quite difficult for the Anti-Virus to detect the same. Whatever the techniques may be, but even the legitimate and genuine programmers are working day and night to develop cures for new virus and future immunization, and all we need to do is to keep our Anti-Virus software updated.

In this post is will let you know how to stay protected by Virusby keeping our Anti-Virus applications up to date and by installing a good Anti-virus application on the computer.


First thing is to get Anti-Virus software for you. There are some big players in the market and you can opt for any of them on the basis of features they carry and the price they have like Norton, MacAfee, AVG, Kaspersky, AVAST.


Once you decide which Security Software suites you the best, go ahead and purchase the same. Most of the security software ship you the installation disk but others only offer online download, and this download information is provided to the customer via an Email.


Once you have the installation disk or the downloaded installation file, just double click on the setup to initiate the setup process.


You can also install the application using the Add or Remove Programs option in the Control Panel.


Once the installation is through, make sure that you register the product online so that it becomes capable of downloading the regular online updates. If the product is not registered then it won’t be allowed by the servers to connect to them and download the updates.

Please note that you should always update the product before scanning the hard drive because your security software will not be able to detect the latest threats if it is not updated.


Make suitable adjustments for automatically scanning for virus and also set schedules for full hard drive scan. This can be done from within the Anti-Virus or from the Windows Task Scheduler.

Steps given above will help you in proactively maintaining the security of your computer against Virus threats. This is very important for any computer system, be it a standalone machine or a networked one.
