Definition of Malware and viruses

Virus is a nothing but a software programme that infects either the executable (exe) files or Object files (Com). It attaches itself to a program in a computer and then replicates itself in way that whenever a corrupted file is executed the virus code is also executed. It can do any type of destructive activities like slowing down the system, preventing you to do certain things or even it can erase data from your computer.

Malware are malicious codes that do not have the ability to replicate itself but once your system is affected by it, your personal information fed through your computer like your credit card information, bank login details and password etc. could be at risk.


Having this much of knowledge you would certainly think of having a robust protection system for your computer so that you can use your computer safely and stay tension-free while using internet and making financial transaction through online applications. You can easily find antivirus software from your computer dealer or you can purchase one from online sites.

As I have already said that we have to live in this environment of viruses and Malware we need not be scared of those, only we need to know them well so that we can take precaution before it’s too late. Once you have installed an antivirus package you need to scan the computer regularly. You should also configure the firewall provided by your operating system to prevent Malware and spamware from affecting your computer. That’s all you need to know as a user of personal computer and internet.
