Why should one use antivirus software and internet security products? The answer to this question is simple. Use antivirus to protect your computer.
What is antivirus software? Antivirus software is nothing but a computer program. Its job is to protect your computer by detecting any viruses and preventing them from harming your computer. It takes action to remove these viruses which are malicious software programs. Software programs that are designed to interfere with the operation of computer to record or corrupt the data are termed as computer viruses.
These can also spread themselves to other computers and throughout the internet. Viruses spread with email attachment. They can be disguised as images, cards or even audio and video files. They also spread by downloads from the internet. They may be hidden in software or programs that the user downloads. It is also important that you are sure of the sender before you open an email or an attachment.
Using antivirus will also prevent your computer being used as a medium to pass infections to other computers. You will not even realize when this happens. Your computer can easily get affected if you are using the internet and you haven’t taken the necessary precautions. Your computer gets the viruses. And then it spreads to others in your email address book. Friends, business contacts and all other people whose information you have in your computer are at a risk of facing this problem. If you do not have an up-to-date antivirus software and a firewall protection you are just asking for trouble. An unprotected computer can be easily detected by viruses, worms and Trojans. If you do not use an antivirus these will attack your computer. These viruses develop very fast. They use unexpected ways. Once your machine is affected, it is not important how the virus got there or what type is it, but the priority is given to removing it from the computer to prevent any further damage.
With an unprotected machine you are not only risking infecting your friends’ computers but also at a risk of losing important personal data stored on your computer which probably is priceless to you.
Some people have also started movements to make people who do not use antivirus legally responsible if their machines are used as a medium for a virus attack.
Keeping all these points in mind one can say that if purchasing an antivirus and using internet security product can protect your computer then it is not an expense but an investment.
