Why is antivirus protection important for your computer ?

Antivirus is a program which makes your system clean and secure from harmful virus, worms and attacks. Antivirus software is vital to maintain proper computer functioning. When computers operate without antivirus programs, they have an increased risk of acquiring malicious software that could completely damage the system, compromise security or delete important information.

Thus, Antivirus programs fully protect the computer by scanning the entire operating system, emails and all downloaded files.

Antivirus Scan all files of your system to find the malicious softwares,worms and Trojans. Even browsing the Internet increases the risk of picking up viruses, spyware, malware and malicious Trojans on your computer. Antivirus programs detect suspicious websites and files that contain malicious programs before they enter the computer. Antivirus programs block malicious tracking software from being downloaded to your computer. Tracking software is used to steal credit card, banking and personal information. Antivirus programs automatically remove spyware, files, Trojans and all other forms of malicious software from the computer. Automatic virus removal is a simple process, and it is also very extensive.

There are lots of hackers in world, who every minute makes and spread millions of new viruses. The main purpose of those hackers is to hack and collect your secret information, like your facebook and email passwords ,your ATM password, your bank account info and lots more type of private information. Other attacks are just for fun to destroy systems. But this really going to serious sometimes. You must have also seen, sometimes in your window that your antivirus stop working, your files automatically deleted, your net connection becomes very slow, task manager disable, even sometimes your window crashes. All these are effects due to such virus.

When we update the Antivirus programs, it updates their virus registry. These updates are important because new viruses are released every day, and they can go undetected if the virus scanner is not up to date. A generic anti-virus checks the database or virus signature and a heuristic anti-virus uses heuristic algorithm and checks malicious character in virus behaviour by different statistical and other advanced means.

So be clear that only installing an antivirus is not sufficient for your security. You have to update it regularly.
