Purpose Of Antivirus Software

Antivirus software is a program designed to prevent the execution of malicious software. There are several types of antivirus programs. Some of them focus on ensuring that malicious code does not infect your computer, others monitor it for any actions that appear to have been performed by an intruder and others attempt to repair problems caused by such infections.

In this guide, we review the aspects of Purpose Of Antivirus Software, advantages and disadvantages of antivirus, types of antivirus software, and What is the name of antivirus software?

Purpose Of Antivirus Software

The purpose of antivirus software is to prevent computer viruses and other malicious programs from infecting your computer. Antivirus software scans files, email messages and websites for signs of viruses or other malware and prevents them from infecting your system.

Prevent viruses

Antivirus software can detect and remove viruses from your computer.

It is important to have antivirus software on your computer as it helps you in preventing the virus infection. This is done by scanning for and detecting malicious programs known as “viruses” that are designed to damage or steal information from a computer, such as credit card numbers or banking information.

Once detected, antivirus software can take action against these viruses by removing them and keeping them from infecting other files or spreading to other computers on the network.

Stop worms and Trojans

A worm or Trojan horse is a type of malware that spreads itself to other computers by exploiting vulnerabilities in one or more programs. It can replicate itself and also do damage to your computer.

If you have a worm or Trojan horse on your computer, it may show symptoms like:

  • Sluggish performance
  • Unusual pop-ups or advertisements
  • Poorly performing programs (especially web browsers)

HIPAA compliance

As a healthcare provider, you may have heard of the Health Insurance Portability and Accountability Act (HIPAA). HIPAA is a federal law enacted in 1996 to ensure that patients’ health information is protected, and those who violate this protection are punished. One of the measures used to enforce these protections is mandatory reporting of any breaches of patient information. This means that if an unauthorized person gets access to your network or data stores, you must report this breach within 60 days.

The best way for a healthcare provider to stay compliant with HIPAA regulations is by using antivirus software on all devices that could potentially store patient data. If you don’t have antivirus software installed on all devices, it’s easy for malware or viruses to infect computers and steal sensitive information—which would put your business at risk for liability under HIPAA rules.

Antivirus software can prevent harm to your computer and loss of information.

Antivirus software can prevent harm to your computer and loss of information. It blocks viruses, worms, trojans and other harmful programs that damage files or track your online activity. The software also protects against ransomware that locks you out of your computer unless you pay a ransom, as well as malware that steals personal data.

Antivirus software scans for malware when it’s installed on your device and updates itself with new definitions whenever necessary. You also need an antivirus program if you’re using Windows 10 Home because Microsoft doesn’t include antivirus features in its operating system by default

advantages and disadvantages of antivirus

Antivirus software is a program that operates against virus protection.

types of antivirus software

When it comes to antivirus software, there are several different types out there. Antivirus software is designed to protect your computer from malicious code and viruses that can damage or destroy your hard drive. The three main categories of antivirus software include freeware, shareware and commercial licenses.


Freeware is a type of software that you can download for free. It’s not the same thing as open source software, which is also free but must be redistributed in its entirety with no changes. Adware is a type of malware that can be installed without your knowledge and display unwanted advertisements on your computer or mobile device. This can slow down your computer and distract you from what you’re trying to do.


Shareware is a type of software that’s available for free but, if you use it often, you have to pay for it. It has a limited number of features but if you like it and use it often enough, then the full version can be purchased.


  • Trialware is a relatively new term, but it refers to software that’s free to download and use for a trial period.
  • It’s like any other type of software, except that you can test it before paying for it. Sometimes you will have to install the program on your computer and then uninstall it before the trial expires, but other times all you need to do is enter your email address and then click “try now” or “download now.”
  • Many antivirus software companies offer this option as an incentive for potential buyers who are trying out different programs before making their final decision about which one they want to purchase (or keep using).

Commercial Licenses

Commercial licenses are usually more expensive than the non-commercial ones, but not always. Some commercial antivirus vendors offer free trials of their products and services before you have to pay for them. You will need to pay for the license after the trial period ends, however. Other commercial antivirus vendors offer a free version of their product that is limited in some way (for example, it may not include all features or some features can only be used on one device).

Free Security Suites

Free security suites are full-featured and offer antivirus, firewall, and antispyware. They’re usually ad-supported and may have limited features—but they can still be an effective choice for protecting your computer.

  • Avast Free Antivirus: The free version of Avast is worth checking out if you don’t want to pay for a premium antivirus suite. It’s available for Windows, MacOS and Android devices (with iOS support coming soon). If you’d rather pay up front than see ads on your desktop, the company offers paid upgrades to its software that remove them from view altogether.
  • AVG AntiVirus Free Edition: For over 20 years now AVG has been one of the most widely used free antivirus solutions around; it’s even available as a browser extension that protects against malware while surfing the web. It also comes with an excellent user interface that makes managing all aspects of your computer’s security easy—and if something does go wrong there are plenty of troubleshooting resources at hand through AVG’s website or forums where users help each other out when issues arise

Check antivirus software before you download it.

To get the best antivirus software for your PC, you need to know what to look for. Here are some things to take into account:

  • Check out its ratings and reviews. You can do this by searching online or by looking at reviews from reputable sources like CNET and PC Magazine. A good antivirus program should have a rating of three stars or above—two stars should be considered average.
  • Consider compatibility issues with other programs on your computer and whether they’ll run together well enough that they aren’t causing problems (or crashing your computer). If there’s only one antivirus program available for your operating system, then it will probably work just fine. However, if there are multiple options available for download in an app store or web browser window, make sure all compatible software can coexist harmoniously before making a purchase decision!
  • Look up any free trials offered by each software developer so you don’t end up paying more than necessary upfront—especially since these costs add up quickly if purchased separately over time… even though they might be cheaper together!
