Using the nuts and bolts real-world scanning engine of the paid-for suite, Kaspersky Free is fiendishly hard for viruses and trojan horses to break down. And we love that it doesn't constantly pester you with nudges to upgrade to the full version. But, ironically, we will just for a moment, because Kasperksy Anti-Virus isn't expensive to buy and yet affords much better protection to your PC or PCs.
Review and where to download: Kaspersky Free. Avast and AVG haven't yet fully merged, despite the former formally acquiring the latter in mid The newly combined company says the two free antivirus products will remain separate, although there's apparently a joint AV package on the way soon. Obviously, though, Avast now has a lot more data to work with, having expanded its effective userbase and, therefore, its threat detection network to a whopping million users.
The latest edition of Avast Free Antivirus adds an automatic gaming mode to mute popups and reduce system load when you're firing up a processor-hungry game, which is very handy indeed, and the interface has been given a clean new overhaul. There's a password manager, too, which is an undeniably good addition to your security portfolio.
It scores well on AV-TEST's widespread malware benchmark and continues a clean sweep against 0-day attacks — presumably that expanded detection network is really helping.
I have been using Comodo Free version for many years. I also run MalwareBytes in parallel. My Rootkit app is from Avira. Go figure. Glad to see Avira still among the tops.
I've never used the other three. As for compatibility, running those two services together can create a snag or two but once they get used to each other it's a nice pair-up. I'd much rather be a bit over secure than lose the use of my PC. Buying parts and setting uip plus convincing Windows that I am the same user as before That's a headache i never want again. I use Comodo and lately I find myself disappointed.
It has incompatibilities with some software that I find unacceptable. Both CosMos and MasterCam 8X are some that will not work with Comodo on the system and the Comodo Company has no intention to fix the compatibility issues.
Since I need some of the programs for school, I have to remove Comodo. At one time it was great but they honestly just to provide good support even for the paid version. I was using Bitdefender Internet Security and before that Avast.
I'm not working at the moment so I need a protection program that is free. I am trying Comodo the free one. Outpost aint no longer available all updates will stop on jan 7 and the program is now not available.
The database updates were a horror by a slow ADSL as a fail reverted to restart. These days NBN it's great. I had problems with the other X64 laptop on Win 7, and took Comodo off, but now Windows 10 seems stable I am putting Comodo back on again.
I just install Panda Antivirus in old laptop with windows xp. Very light and useful interface, but after one day i have two Blue Screen O. I used for a while, and was very happy with it. So, does Windows 10 Need Antivirus? The answer is yes and no. However, with the rapidly evolving malware threats, software and hardware vulnerabilities, does sticking with the built-in Windows Defender tool as your primary Antivirus program enough to protect your computer from malware and cyber attacks?
You can also run the Windows Defender tool from a from a USB drive, even when you are not connected to the internet. Windows Hello works with compatible apps like iHeartRadio and Dropbox, so you can bypass the password and breeze right through with facial recognition biometric security. Windows Hello lets you use your digital wristband, smart watch, phone, and other companion devices to quickly unlock your Windows 10 PC without using a password. Windows 10 provides new features and security updates for free on an ongoing basis.

We still recommend going for Kaspersky Security Cloud Free, which has even less of a system impact, better malware protection and useful extras, but there's absolutely nothing wrong with using Windows Defender as your primary antivirus solution.
Read our full Windows Defender review. 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.
Read our full Avast Free Antivirus review. AVG shares a decent, if unspectacular, malware-detection engine with its corporate sibling Avast while having a much lighter system-performance impact. While the latter is almost a free security suite with lots of bells and whistles, AVG AntiVirus Free is the quiet, neglected child that gets the hand-me-downs.
The good news is that AVG's wide range of customization options and its file shredder and system optimizer are still available, and its interface is open and easy to use.
Worst of all, given its middling malware detection and dearth of extra features, there's no convincing reason to choose AVG AntiVirus Free over the built-in and overall better Microsoft Defender. Malwarebytes Free, formerly called Malwarebytes Anti-Malware, is not antivirus software. Instead, it's a very useful malware-removal tool. What's the difference? Unlike antivirus software, Malwarebytes Free can't prevent a PC from being infected.
But it does an excellent job of cleaning out malware that's already on your system, as well as removing legal adware and potentially unwanted programs that antivirus software often ignores. Malwarebytes Free doesn't interfere with any antivirus software that's already installed, so it's perfectly safe to install it alongside one of our recommended brands.
Just don't upgrade to the paid Malwarebytes Premium, true antivirus software that does poorly in lab tests and which will conflict with other AV programs.
