Anti virus software review top ten reviews viruses worms

However, there are a couple programs that work in tandem with other antivirus software. Both AVG and Avast work alongside other protection software to add a second layer of security, catching threats your main program may miss. If you install Avast or AVG as a secondary antivirus program, make sure to install it after your main antivirus.

Otherwise, your primary program will require you to uninstall it before completing the installation process. It includes password managers, data backup, both antispam and antiphishing tools, and web controls to keep tabs on what your employees are doing online. However, keep in mind that there has been some suspicion about Kaspersky using its security programs to gather sensitive information and spy on government employees, even in their own homes.

Another good business protection program is Avast Business Antivirus. It also includes a vulnerability scanner to help keep all software on your computers updated and plug up any hole where hackers and ransomware could sneak in. Avast also monitors your webcams to ensure no one is accessing them without permission. Firewalls inspect the packets of information coming through your internet connection and block those that are harmful.

Hardware firewalls are included as part of your internet router. But even if a packet of information comes from a trusted source, there still can be a threat inside that the hardware firewall is unable to detect. Some of the most common threats caught by firewalls are ransomware viruses that hold files hostage until you pay the developers a fee , and Trojans files that look legitimate on the outside but inside have another threat like a rootkit inside.

Both of these threats are used by hackers as a way to get personal information and use it for financial gain, or sometimes just to wreak havoc.

Personal firewalls boot neighbors off your internet and block them from stealing your service in the future.

Sophos Home Premium does its job economically, offering reasonable protection from malware at an affordable price. Because it's spun off from Sophos' enterprise software for business clients, Sophos Home Premium lacks many of the bells and whistles other security suites offer, such as a password manager, identity theft protection service or VPN service.

What Sophos Home Premium does have is the essentials: ransomware rollbacks, webcam defenses and protection against keyloggers, malicious websites and boot-sector and fileless malware. It also has a web-filter system for parents and an online management console from which you can tweak most of the settings. Some people might demand more from an antivirus suite, but anyone who would rather buy only what they need will appreciate Sophos Home Premium's just-the-basics approach.

Read our full Sophos Home Premium review. A good paid antivirus suite is a digital-protection jackknife, often bundling in parental controls, identity theft protection, a password manager, backup software, cloud storage, a firewall, a system optimizer and software for Mac, Android and iOS as well as Windows. But what if you just want Windows antivirus software without all of those pricey extras? And what if you can't afford to pay for antivirus software?

One of the best free antivirus programs might be exactly what you need. Free antivirus software used to be a step down from the paid software and involved trade-offs.

The protection wasn't as good and you'd either have to put up with ads filling your screen or with constant nags to upgrade to a paid program. That's all changed. One of the best antivirus makers, Kaspersky, offers a free version with the same excellent malware protections as its paid offerings.

Its top rival, Bitdefender Antivirus Free Edition, has been officially discontinued, although Tom's Guide readers can still download it with this link.

A merger between the biggest names in free antivirus, Avast and AVG, created a combined malware-detection engine that's much better than the sum of its parts. Meanwhile, Microsoft's built-in antivirus software, Windows Defender, aka Microsoft Defender Antivirus, has gone from being a joke to being one of the best antivirus programs out there, free or paid. You can now get free antivirus protection that's as good as anything you pay for.

So here are the best free antivirus programs based on their protection, system impact, ease of use and extra features. Kaspersky Security Cloud Free 2.

Bitdefender Antivirus Free Edition 3. Windows Defender Antivirus 4. Avast Free Antivirus 5. Kaspersky Security Cloud Free Antivirus may be the best free antivirus program we've ever seen. It has excellent malware protection, a decent set of extra functions and features, and a system-performance impact so small that our computer actually sped up after we installed the program.

Bitdefender Antivirus Free Edition has been officially discontinued, and we're not sure how long Tom's Guide readers can still download it. It's the best "set it and forget it" free antivirus option. It's now one of the best antivirus programs altogether. You don't have to install or download it — it's already on your PC. If you want an unlimited password manager or a hardened web browser, Avast Free Antivirus might be for you.

Its malware protection is much better than it once was, although its performance impact is fairly heavy. Avast's stepsister AVG has the same malware-detection engine, but lacks Avast's full slate of useful extra features.

But it does have a file shredder and system optimizer. We have to mention one program that's not antivirus software, but which we recommend anyway: Malwarebytes Free.

While antivirus tries to stop malware from infecting your machine, Malwarebytes functions as the cleanup crew, sweeping out less-harmful adware or potentially unwanted programs that the antivirus software ignores.

It works well alongside any antivirus program. Kaspersky doesn't talk much about its free antivirus product, and you might have a hard time finding the free Kaspersky software download page on the company's website.

That's too bad, because Kaspersky Security Cloud Free is the best free antivirus product we've ever tested. We've never seen such a combination of excellent protection and extra features in a free antivirus program. It's got a bright, comprehensible interface, a lot of customization potential and Kaspersky's unbeatable malware protection. The program also lets you schedule scans, and its performance impact was so small that it actually sped up our test machine a bit.

Kaspersky's useful extra features include a file shredder, an on-screen keyboard and an email scanner. The password manager and VPN service are fairly limited, however, unless you pay. Read our full Kaspersky Security Cloud Free review. Bitdefender has officially discontinued Antivirus Free Edition, and it will be supported only until June 30, We still love it and you can still get it , but proceed at your own risk.

Compared to premium paid antivirus programs that are big, heavy and loaded with extra bells and whistles, Bitdefender Antivirus Free Edition is like a '60's sports car, stripped to the essentials but still providing plenty of power.

Bitdefender Antivirus Free Edition offers nothing but the basics. There's no password manager, no gaming mode, no quick scans and no scan scheduling. You can manage the software from the program's System Tray icon, but you don't really need to interact with Bitdefender Antivirus Free Edition after its installation. Yet Bitdefender Antivirus Free Edition has the excellent Bitdefender malware-detection engine, which sits just below Kaspersky and Norton in the lab-test rankings.

It's the best free antivirus software if you want a security solution that you can set up and then forget about. It's also perfect if you need to protect the computer of an elderly relative but don't have time to manage antivirus software from afar. Read our full Bitdefender Antivirus Free Edition review. Microsoft's built-in antivirus software is now a heavy hitter.

While Windows Defender, aka Microsoft Defender Antivirus, doesn't quite beat Norton or Kaspersky in malware-protection lab tests, it comes out ahead of Avast, AVG and most other free antivirus products while operating almost entirely behind the scenes. You won't be getting many extra features with Windows Defender itself, yet Windows 10 does have parental controls, a gaming mode and protections for its own Edge and Internet Explorer browsers.

There's no built-in VPN, but you also won't be bothered by pop-ups trying to upsell you to paid antivirus software. As for a password manager, there's a stealth one built into the Microsoft Authenticator app for Android and iOS that syncs with the Edge browser, as long as you're signed into your Microsoft account on all devices. We still recommend going for Kaspersky Security Cloud Free, which has even less of a system impact, better malware protection and more useful extras, but there's absolutely nothing wrong with using Windows Defender as your primary antivirus solution.

Read our full Windows Defender review. Avast Free Antivirus has the best assortment of extra goodies of any free antivirus program, including a hardened browser, a gaming mode, a Wi-Fi network scanner and a recently added ransomware shield.

Unfortunately, the unlimited password manager has been discontinued. The program is also very customizable, letting you tweak its appearance and functions to suit your style. It even offers limited access to Avast's VPN service. However, Avast Free Antivirus caused a pretty heavy system load in our testing and its scans took a long time. It also kept nagging us to upgrade to Avast's paid antivirus protection, and played bait-and-switch with features that looked like they were free but weren't.

Most significant of all, the malware protection in Avast Free Antivirus is a peg down from Kaspersky's or Bitdefender's, whose free programs also bothered us less about paid upgrades and had lighter system loads. Amazingly, Microsoft provided no built-in protection for Windows back in the days of Windows 95, 98 and XP. Using Microsoft Defender for threat detection should be your starting point for the best antivirus security on Windows and most people will find they don't need to go any further when it comes to nailing down an antivirus solution for identity theft protection.

However, keeping your personal data safe and guarding your privacy extends beyond virus protection, and that's where third-party antivirus software shines. A full AV software protection package can monitor your Windows operating system as well as MacOS, iOS and Android devices and include a password manager, secure online backup, identity theft protection, a VPN, parental control, webcam protection, protection against phishing and malicious websites and more -- all worthwhile security suite tools that can keep your data secure and guard your privacy.

To help you decide on the best antivirus software for your needs, I've put together a list of the best antivirus products for Windows 10, encompassing both free antivirus programs and subscription options.

We regularly research and test our options to determine which software leads the pack, and we update this list periodically based on those tests. We would also like to note that antivirus software isn't the only security feature you should invest in. A secure virtual private network to protect your internet traffic, a password manager to keep track of login credentials and an end-to-end encrypted messaging app to stop others from spying on your communications are all essential in protecting your personal information.

Cybercriminals are becoming increasingly more sophisticated and high-profile attacks like the Columbia Pipeline hack are becoming more commonplace, which is concerning.

In fact, it is one of the best antivirus software. Note that Microsoft changed the name of Windows Defender to Microsoft Defender and has expanded the service to other platforms.

This free antivirus program is built into Windows and it's turned on by default, the antivirus engine does its thing, and this antivirus solution will cover the basics of internet security. Microsoft pushes new updates frequently. Defender also lets you tune the level of protection you want, giving you control over blocking potentially unwanted apps and protecting folders and files from a ransomware attack. Note that Windows 10 will automatically disable its own Windows Defender antivirus when you install third-party antivirus.

If you uninstall the third-party protection, Windows 10 will turn back on its own antivirus. Norton antivirus provides industry-leading security software for PC, Mac, and mobile devices. Note, we don't think antivirus protection is terribly useful outside the Windows realm. In addition to malware and virus protection for your computer and mobile device, this antivirus suite provides GB of backup to the cloud, safe-browsing tools, a secure VPN, password manager, parental controls and LifeLock identity theft protection and fraud alert.

While not all of those services are necessarily best in their respective class, getting them all in one package is a compelling option.
