Why Do I Need Antivirus Software?
For as long as computers are and will be in existence, whether connected to the Internet or not, there’ll always be a need for antivirus software. There’ll be no time when people, whether mischievous youths looking for a thrill or hardened cybercriminals seeking to exploit billion-dollar businesses, will stop trying to find ways to commit fraud, cause widespread harm, or simply experience the rush of breaking into a computer.
Antivirus software is a significant tool to help prevent these attacks. Not every type of cyberattack can be prevented with antivirus software, but it may be a superb advantage when trying to prevent intrusion into a computer.
Though not every intrusion into a computer is supposed to cause harm or steal valuable information, that does not mean that the attack is not dangerous. All intrusions to a computer exploit what is called a vulnerability, or a weakness in the computer’s operating system or other applications that may serve as an access point to an assault. After even the most benign of an intrusion exploits a vulnerability, it sends a signal to others that this computer was infiltrated. This opens the door wide open to worse strikes.
When seeking to purchase antivirus software, be sure to purchase a reliable and well recognized, subscription-based software. This is vital, as the manufacturers of the type of software will have the ability to maintain their readers’ computers protected with real-time upgrades that scout out the latest threats.
What Antivirus Software Can Protect Against?
Antivirus protection isn’t only a means to block computer viruses, as the title may employ. (Some folks believe that all intrusions to a computer are known as viruses, but that’s a misnomer.) For example, here is a list of the ways a good antivirus program can assist in protecting a computer with information on it:
Antivirus — Starting with the obvious, an antivirus program will protect against computer attacks or viruses that mean to harm a computer.
Rootkit protection — This prevents rootkits, which are embedded deep within a computer so as to conceal other malware, from launching on a computer.
Bot protection — This alerts a subscriber when a cybercriminal is trying to remotely take over a computer to use as a supply for automatic spamming and other offenses. Bots are what botnets are based on (groups of ordinary people’s computers which were infected in order to carry out attacks on other things).
Worm protection — By definition, worms attack networks as opposed to computers themselves. However, rats may take payloads of malware which might be deposited on computers, which will then run harm. Antivirus software can prevent this form of assault – stop computer worms.
Trojan horses — Antivirus software can not stop someone from being duped into believing that a desirable downloaded program or document is valid. However, antivirus software can warn them if malware is found inside a Trojan horse document.
Spyware — Antivirus software can detect when a computer was infected with spyware, or software that is meant to collect data of steal or usage information, even if the source came from a reputable, legitimate source.
Messaging protection — Whether it is instant messages or emails, antivirus software can warn users when these messages contain dangerous attachments or fraudulent links. Immediate messaging security is important now.
Respectable antivirus software applications should also include some type of recovery tool. No antivirus program is infallible (and when a person claims to be, they are lying). A recovery system will help rid a computer of any malware which passed through its own defenses. Also, antivirus software is not only for the computer that’s attacked from the Internet. Viruses can be spread through cellular storage drives. Conceivably, an individual could plug these devices into a computer in a library, and then bring it home to a computer with no online capabilities, and spread some type of malware this way.
Other Prevention Methods
While having antivirus software protection is an important step in maintaining a computer absolutely free of malware, there are still a few other things someone can do to maintain their computer as clean as possible.
Keep computer applications upgraded — Operating system software is one of the crucial points in which cybercriminals try to exploit vulnerabilities in remote computers. However, to stay on top of known attacks, operating system manufacturers constantly upgrade their software at no cost to be able to help protect their patrons. These upgrades are free and could be set up to occur automatically.
Practice safe Internet habits — There are lots of ways that cybercriminals can insert malware on computers, and a few of these methods involve deceiving dumb users into accepting the offending software freely. Never open attachments or follow hyperlinks from anonymous sources. Never give out private information, like passwords, even though it seems to come from an administrator. Use strong passwords on a regular base.
These methods, combined with having antivirus software, provide a computer user a much greater likelihood of staying protected from cybercriminals.
