This guide will show you the best free antivirus software for your Windows PC. Some of these offer a premium version that you can buy for additional features, but its not necessary because youll still get excellent protection.

What Protection the Best Free Antivirus Software Should Offer?

There is numerous protection that free antivirus software provides. The following are a few of the most notable protections:

Malware Protection

Antivirus software primarily serves as a preventative measure. It looks for any possible infection and then attempts to eradicate it. Keep in mind that much of this is done before the virus causes any damage to the system. As a result, the majority of infections are detected and blocked before they can cause any damage to your computers. Without your knowledge, an antivirus program may fight multiple viruses in a single day. Avast and Norton are two of the most widely used antivirus programs on the market these days.

Blocking Spam

If you do a brief scan of how viruses get into the computers of their victims, youll be surprised at how many infections use pop-up adverts and websites to get into machines. Viruses exploit pop-up advertising and spam websites as one of the most common ways to infect your computer and destroy your files.

Bullguard Internet Security, for example, acts against harmful virus-infected adverts and websites by denying them direct access to your computer network.

Protect Against Data Theft

To gain access to their victims computer, hackers typically utilize malware or virus applications. They install malware on the victims PC without the victims awareness. Hackers achieve this by sending victims infected emails. The hacker can then quickly gain access to the files and programs that they desire.

After that, they can do whatever they want with the victims data; they can destroy, damage, or steal it in order to demand ransom later. Antimalware- ware solutions like Malwarebytes either impose an antihacking lock on the computer network or run frequent scans to detect the presence of any hacker or hacking-based apps.

Removable Devices Scan

Consider how many times youve used devices like USBs to move data to and from your computer. Isnt it countless?

You may have experienced computer slowdown or even a computer crash after attaching a friends USB drive. This is because the USB or detachable device was used as a viral dissemination device. So, should you avoid using portable devices because you never know which USB can be infected?d?

No! Simply install antivirus software that will scan any removable devices for potential viruses, ensuring that no viruses are transported. With that out of the way, lets take a look at all the anti-virus software that you should consider.
