Viruses, malware, Trojan horses, worms, adware, zombies – the list of software cybercriminals use is long.

Avira Antivirus is a robust antivirus software with everything you need for your devices. Best part? It’s completely free. Brownie points out, it contains a free password manager and a virtual private network (VPN). Avira also has a paid version that offers additional protection against online threats and ransomware.
“It is efficient for scanning computer files. The best part is the auto-update of its virus database, which enables the software to keep up todate and protect your computer and files from harmful viruses.”
– Avira Antivirus review, Hassan A.
“There are times when it emits virus alarms that do not correspond. This mostly occurs when software the antivirus is not aware of is installed and blocks files that are not threats.”
– Avira Antivirus review, Raymond S.
As the name suggests, Bitdefender Antivirus Plus 2020 works as more than just antivirus software. The tool protects against the growing cyber threats of viruses, malware, and ransomware.
Its anti-phishing and anti-fraud features are the other notable web security attributes. It flags malicious websites or links before users click, protecting them against internet-based threats.
“As someone who does a lot of online banking and shopping, I’m always concerned about falling victim to scams and fraudulent activities. But with Bitdefender, I can surf the web with confidence, knowing that the software is actively blocking any suspicious activity and keeping my personal information safe.”
– Bitdefender Antivirus Plus 2020 review, Ashesh K.
“The biggest issue with Bitdefender is that it sometimes doesn’t provide up-to-date protection against newly released malware and viruses. For example, there was recently a new virus circulating on Facebook Messenger that was undetected by Bitdefender’s security software..”
– Bitdefender Antivirus Plus 2020 review, Hicham S.
 Emsisoft Anti-Malware is a strong antivirus program that detects and prevents all kinds of malware, including ransomware. The software comes with capabilities like a file guard that scans for 10 million+ malware types and a behavior blocker, which stops new and unknown threats by analyzing their behavior.
Users can try Emsisoft for free with its 30-day free trial.
“Its modern, clean, intuitive, and easy-to-use interface allows any user to start without going to a technician in this type of software, which saves time. It is also extremely light, so it does not harm the performance of the equipment, something that with other software is impossible.”
– Emsisoft Anti-Malware review, Marybel M.
“If you have a program other than Windows, it may not work perfectly for you. Also, sometimes it throws some things as dangerous but (are) not.”
– Emsisoft Anti-Malware review, Chloe T.
With its free download for Windows, Kaspersky AntiVirus is one of the widely used antivirus software provided by Russian cybersecurity company Kaspersky. This tool provides essential protection for your device, like scanning removable devices and removing malware. It also supports safe browsing.
The software is very easy to install, and the user interface is simple, making it a breeze for even beginners to use it.  All this makes it a reliable choice for those who want basic virus protection without complicated features.
Apart from the free software it provides, Kaspersky has three different antivirus software plans with additional features like online payment protection and adware removal. These paid plans have a 30-day free trial.
“I believe that the best part about the Kaspersky antivirus software is how easy it is to use. So far, it’s the best antivirus software that I’ve used…Another feature I like is the beautiful and aesthetically pleasing user interface. Not only does the user interface look good, but it is also straightforward to use without the need for any training. It automatically scans any external hard drives when plugged in without the user scanning the storage drives manually. This feature is essential since many users forget to scan their external storage drives manually before opening them.”
– Kaspersky AntiVirus review, Chandrika P.
“It slows down our system, taking a lot of memory to run. Scanning files take more time. There is less information provided about detected threats.”
– Kaspersky AntiVirus review, Vinoth K.

“Malwarebytes is an easy-to-use, well-designed, and perfectly silent partner in protecting your digital assets from assault. It blends perfectly into the background, is unobtrusive, and almost disappears to the point where you forget it’s running: the best possible interaction for an anti-malware suite.”
– Malwarebytes for Home review, Zach M.
“During whole PC scans, it hangs a lot and disturbs and interrupts other processes, which is very annoying.”
– Malwarebytes for Home review, Snehal V.
McAfee AntiVirus Plus offers precisely what we expect from antivirus software: real-time protection, scanning for malware, and online safety. The tool is suitable for different devices like PCs, mobile phones, or Macbooks. Users can test out McAfee AntiVirus for free with a 30-day trial on all their devices.
“I use the one-device plan from McAfee. It blocks viruses, videos, and other high-data-consuming content on websites. The software is very fast and does not show any performance-related issues. It also blocks harmful websites and gives threat pop-ups. The quick scan option scans the PC very fast, and it can be used periodically. The price is competitive compared with other available options.”
– McAfee AntiVirus Plus review, Jagruti G.
“It can be frustrating to use at times due to its excessive resource consumption, complicated interface, and challenging navigation, which are compounded by frequent notifications and pop-ups.”
– McAfee AntiVirus Plus review, Premkumar A.

– 360 Total Security review, Raymond C.
