How to Find the Best Antivirus Software

How to Find the Best Antivirus Software

Finding the best antivirus software is important so that your computer or mobile device is kept secure.

This is why I am going to show you how to find the best antivirus software so that you have a high level of protection against threats such as viruses and malware.

We’re going to go over the main signs that you may experience if you have a virus on your device, what features you should look out for with an antivirus program, and also what the best antivirus software is to use.

What is a computer virus?

A computer virus is a malicious piece of software or code that is installed onto your device without your knowledge.

It works by infecting one computer and then spreading to other computers to cause more damage. This could be via a local network such as a LAN, or it could be over the internet via email attachments or unsecured websites.

The first-ever computer virus emerged back in the early 1970s, and since then, they have become a real problem for everyday computer users. In fact, there are nearly 1 billion viruses circulating around the internet at the minute, and 350,000 new pieces of malware are discovered on a daily basis.

There are different types of computer viruses, and they are designed to do different things. Sometimes a virus and malware get used interchangeably. Malware is malicious software and is a type of virus that can spread via email, spam links, and other methods. Some more types of computer virus include:

  • Trojans – like a ‘Trojan Horse,’ this type of virus creates hidden backdoors into your computer system so that malicious individuals can steal your data and information.
  • Spywaremany viruses are designed to spy on you and what you are doing online. Spyware installs itself on your computer and monitors what you enter – for example, your passwords or your bank details and steals your data.
  • Adwarethis kind of virus will infect your computer with ads and overrun your system, often causing it to crash.
  • Ransomware – this computer virus infects your computer and essentially ‘locks’ it so you can’t access anything and then asks you to pay a fee for your device to become usable again.

These are just a few examples of different types of computer viruses, and they range from aiming to commit fraud by stealing your details to simply being designed to cause havoc on your computer.

It isn’t just Windows computers that are susceptible either.

Both Mac computers, as well as devices that run on Linux, can be exposed to a computer virus.

iOS and Android mobile devices can also get viruses. Here’s how to encrypt them.

What is antivirus software?

The good news is that even as scary as computer viruses sound, and there are things that you can do to prevent your device from being infected.

Antivirus software is designed to protect you against being infected by a virus. The software itself will have a scan function so you can scan your files and folders to ensure no malicious code of the software is present.

If it is present, the program will delete it, and most antivirus software also comes with preventative measures to help stop your computer from being infected in the first place.

There are differences between antivirus software and wider internet security programs but there is often a crossover in terms of features.

Signs that you have a virus on your computer

Some computer viruses are very easy to spot – ransomware, for example – because they are designed to be intrusive and obvious.

However, not every type of computer virus is immediately noticed, and they often work in the background of your computer. There are some signs that you can look out for to see if you have a computer virus before you run an antivirus scan.

Your computer has slowed down

Most viruses are created to cause damage, and this can result in using a lot of processing power or even eating into your hard drive space.

If you have found that your computer takes a lot longer to load up, has much less storage space, or that programs aren’t opening as quickly as they used to, your device could be infected.

Your homepage has changed

If you open up your browser and instead of your usual homepage, a new site has popped up, and you can’t remember changing it, then you might have a virus.

This is one of the most common signs that your computer has been infected, and you might also be unable to change it unless you get rid of the virus itself.

Intrusive pop-ups

One way a virus can crash your computer or just cause a lot of annoyance is to have frequent pop-ups appearing on your desktop.

We’re all used to pop-ups on a website, but if you find ads or malicious windows appearing on your desktop, then this is usually a sign that you need to scan your system for malicious software.

Sending out spam emails

Maybe your friends have contacted you to say that they received a spam email from your account, or you’ve gone into your sent folder and discovered a load of emails you don’t remember sending.

This could also be a sign that you have a computer virus, and you need to take action to get rid of the infection.

What is important with antivirus software?

Antivirus software varies greatly in terms of the features it offers and how good it is at detecting threats.

You may only need an antivirus scanner to find out if your computer is infected, however, it is worthwhile exploring some of the additional security features this type of software can offer.

Scanning your system

First and foremost, you need your antivirus to be able to scan your files and folders for potential threats.

This is its primary job.

Some antivirus programs do this better than others, and some have deeper scan functions that can get right into all the hidden files on your device. The deeper the scan, the longer it will take, but you will have more of a chance of uncovering viruses and other threats on your system.

Every antivirus program will let you scan your computer or device, and detection rates can vary.

Automatic updates

New virus threats are emerging every day. In fact, they can emerge by the hour, and millions are discovered every year.

This is why you need your antivirus to update automatically in the background. It gets information about new viruses and makes sure that your system is protected from them. If your antivirus software requires you to search for updates manually, then this can leave your computer very exposed.

You might forget to do this or only do it every so often, and by the time you get around to it, new threats will likely be floating around the internet and ready to infect your device.

Easy to use

Let’s face it, even though ensuring your computer is free from viruses is important, it isn’t the most exciting job out there for most people.

Many see it as a distraction from what they are doing. This is why your antivirus software needs to be easy to use. You won’t want to spend a long time trying to navigate a difficult and confusing UI when you could choose an antivirus that has a very clear layout so you can make sure you are protected and up to date.

Luckily most antivirus software is quite easy to use as it is designed for mass use among casual and expert internet users alike.

Simultaneous devices

It used to be the case that you would buy an antivirus product and just install it on your desktop PC or a laptop.

This is because it was the only way you could access the internet, and even when mobile phones began to get internet access, they weren’t really used for this function. Nowadays, we use so many different devices that are constantly connected online.

From your laptop or desktop to your Smartphone and/ or tablet. The market has changed rapidly, and now we need to have several devices protected at the one time. Depending on what subscription you take out, most antivirus software will allow you to use it on various devices at once.

This is important because if you only have a license to install it on your laptop, for example, you will be leaving your Smartphone exposed, which is a real danger, especially if you do things such as online banking and emails.

Support options

Most antivirus programs are easy to set up .and scan your system however if you do encounter any problems then you will want to get help.

Some antivirus companies offer better support than others. If they just offer email support, then you could be waiting days for a reply, whereas with live chat, you can get a response right away.

Also, look out to see if they have a knowledge base that often has many articles, FAQs, and even videos to help you.

Complete security online

While just having the ability to scan your system and remove threats is great, you may want to have a more comprehensive internet security solution.

Many antivirus programs now have extra functions and features to help you stay safe online.

This can include a VPN to provide further encryption, browser shield which will warn you if you click on an unsafe link or visit an unsecure website, parental controls so you’re in charge of what people can access from your network as well as a password manager to ensure your passwords are safe.

These are all things that are important in today’s connected world, and alongside protection against viruses, malware, and other malicious programs, they will help to keep you safe on the internet.
