Why You Need Antivirus Software?

Antivirus software’s are programs that help protect your computer against most viruses, worms, Trojan horses, and other unwanted invaders that can make your computer “sick.” Viruses, worms, and the like often perform malicious acts, such as deleting files, accessing personal data, or using your computer to attack other computers.

To help keep your computer healthy, install valid Antivirus. You must also ensure both the program and the virus signature files are up to date. These updates are generally available through your products.

What is Antivirus?

Antivirus software is a type of utility used for scanning and removing viruses from your computer. While many types of antivirus (or “anti-virus”) programs exist, their primary purpose is to protect computers from viruses and remove any viruses that are found.

What antivirus software can protect against?

Antivirus protection isn’t just a way to block computer viruses, as the name may apply. (Some people think that all intrusions into a computer are called viruses, but that is a misnomer.) For example, here is a list of the ways a good antivirus program can assist in protecting a computer with data on it:

  • Antivirus – Starting with the obvious, an antivirus program will protect against computer viruses, or attacks that mean to damage a computer.
  • Rootkit protection – This prevents rootkits, which are imbedded deep inside a computer in order to mask other malware, from establishing in a computer.
  • Bot protection – This alerts a subscriber when a cybercriminal is attempting to remotely take over a computer to use as a source for automatic spamming and other crimes. Bots are what botnets are based on (groups of ordinary people’s computers that have been infected in order to carry out attacks on other entities).
  • Worm protection – By definition, worms attack networks rather than computers themselves. However, worms can carry payloads of malware that can be deposited onto computers, which will then do damage. Antivirus software can prevent this sort of attack – stop computer worms.
  • Trojan horses – Antivirus software can’t stop a person from being duped into thinking that a desired downloaded program or file is legitimate. However, antivirus software can warn them when malware is detected within a Trojan horse file.
  • Spyware – Antivirus software can detect when a computer has been infected with spyware, or software that’s meant to either collect data of usage or steal information, even when the source came from a reputable, legitimate source.
  • Messaging protection – Whether it’s instant messages or e-mails, antivirus software can warn users when these messages contain dangerous attachments or fraudulent links. Instant messaging security is important today.

Reputable antivirus software programs should also come with some sort of recovery tool. No antivirus program is infallible (and if one claims to be, they’re lying). A recovery system will help rid a computer of any malware that passed through its defences.

Also, antivirus software isn’t just for computer that are attacked from the Internet. Viruses can be spread via portable storage drives. Conceivably, a person can plug one of these devices into a computer in a library, then bring it home to a computer with no online capabilities, and spread some kind of malware in this manner.

Threat Scenarios

A Trojan horse gets onto your system by pretending to be useful, but once inside the walls, it releases a malicious payload. You say you don’t store personal data? How about your email address—that’s about as personal as it gets. A Trojan might try to capture your email address and password, or insert itself into financial transactions to drain your bank account. That’s bank robbery with no need for a mask or a gun.

If your computer gets co-opted into a botnet, the bot herder can make it do just about anything, including spewing spam, participating in a denial of service attack, or serving as a peer-to-peer command and control server. If your ISP detects GameOver Zeus traffic coming from your IP address, you might find yourself cut off from all Internet access.

How would you like to turn on your PC and see a message demanding that you pay ransom to regain access? Ransomware comes in many varieties, none of them pleasant. Even if you pay up, there’s no guarantee you’ll get your data back. You might have to reformat and start over.

Here’s another unwelcome possibility. If the bad guys manage to infest your PC with malware that gathers passwords and personal information, they might well parlay that data into full-blown identity theft. You might not know a thing about it until you get the bill for a credit card account you never opened, or find that there’s a lien on your house.

Other prevention techniques

While having antivirus software protection is an important step in keeping a computer free of malware, there are still some other things a person can do to keep their computer as clean as possible.

  • Keep computer software updated – Operating system software is one of the key points in which cybercriminals attempt to exploit vulnerabilities in remote computers. However, to keep up with known attacks, operating system producers constantly update their software for free in order to help protect their patrons. These updates are free, and can be set up to happen automatically.
  • Practice safe Internet habits – There are many ways that cybercriminals can insert malware onto computers, and some of these methods involve fooling ignorant users into accepting the offending software freely. Never open attachments or follow links from unknown sources. Never give out confidential information, such as passwords, even if it appears to come from an administrator. Use strong passwords on a regular base.

These methods, combined with having antivirus software, give a computer user a much better chance of staying protected against cybercriminals.
