Miglior antivirus 2006

We have combined all our Android security technologies into one app — Kaspersky Internet Security for Android. This app is also available under the license for Kaspersky Security Cloud. Please note Kaspersky Security Cloud for Android has been discontinued.

Only final, officially released operating systems are supported by the product. Please note that Kaspersky Security Cloud functionality may be limited on certain devices and operating systems.

Unfortunately, with this year's debut of the Norton Protection Center, Norton AntiVirus has lost that uncluttered usability. The Norton Protection Center appears both as a separate icon in the system tray as well as a separate window within the software's control console. Most of the Protection Center's functions are useful, such as the alerts it sends if you don't have the latest virus definitions or haven't run a system scan in a while and the bar graph in the Status window.

However the Protection Center is focused on upselling Symantec's other products to you rather than providing any new, useful security information. For instance, if you ask to learn more about data recovery, you're taken directly to the Norton SystemWorks product page on Symantec's Web site. Norton AntiVirus does offer some important security feature enhancements, such as protecting your browser's home page against spyware hijacks.

More important, Norton AntiVirus expands its detection and removal to spyware and adware programs, catching them both in real-time and full-system scans; plus, virus and spyware definition updates are now updated daily. Norton AntiVirus allowed adware to install and run first, then alerted us to the problem. A good free antivirus — like the ones we recommend on this page below — is a perfectly reasonable option for protecting your PC, with Microsoft Defender now the best we've ever seen it.

That said, premium antivirus programs offer extra features above and beyond the fundamentals. A robust system of parental controls could be a huge win for those with kids, for example. Or a dedicated anti-ransomware layer of protection that only comes with the paid-for product could help catch one of the most dreaded infections and halt it in its tracks. For more on this, read our full piece on whether free antivirus is enough to protect you.

Or just keep scrolling as we reveal today's best free antivirus software providers Paying for a premium service means you get more features like spam filters, parental controls, system scans and advanced firewalls. This makes them more suitable for power users, those who want a bit of extra security and anyone who needs their system to run as smoothly as possible.

It also means you avoid annoying pop-ups that try and tempt you to upgrade to the full version. In fact, these days you can get top quality protection absolutely free, with just about every single major vendor out there offering a free antivirus. Avira Free Antivirus is today's best free security download If you're determined to get free antivirus, we strongly suggest that you go for our pick of best security downloads - Avira Free Antivirus.

We've highlighted its long list of features below, together with information on how well it performs at independent testing labs. A very impressive freebie.

That's pretty good for a freebie, and why we have no qualms at all in naming it as our 1 best free antivirus download. As well as the essential security smarts, we also love the clean, friendly interface and the fact it has a track record of throwing up minimal false positives. In fact, the list of features reads more like a fully paid premium package.

It throws in identity protection, a password manager, anti-scam protection to prevent phishing attempts, and even a PC cleaner to keep your system spick and span. If there's one thing we'd change then it's the tad overeager badgering - although popups and advertisements are very common to free products, and that doesn;t prevent us from wholeheartedly recommending Avira Free Antivirus.

Review and where to download: Avira Free Antivirus. 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's free antivirus - now branded Avast One Essential - 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. Less impressive is the slight negative effect Avast has on software launch times, and its slightly popup-heavy attitude. Review and where to download: Avast Free Antivirus. Microsoft Defender formerly Windows Defender was generally seen as a bit of a joke in the not-too-distant past.

It performed terribly by most measures and was a good advert for why you should really pay for antivirus. But as we explain further up this article, Microsoft Defender has come on leaps and bounds and can now legitimately be mentioned in the same company as Bitdefender, Norton and Kaspersky.

As well as very solid virus protection, Defender has extra bits and bobs like a ransomware shield, webcam protection, privacy tools and even basic parental controls and cloud backup.

And the best bit No need to download a thing, just find it in your menu and get protected straight away. Read more and see how to use: Microsoft Defender review. The paid-for version of Kaspersky's Windows security software frequently tops charts of best virus prevention solutions and AV-TEST once again gave it full marks across the board in its latest round of testing.

As you would expect, Kaspersky Free is a scaled down version of the full program - a tool that we really like more on which below. The free version ditches additional features such as privacy protection and safe payment sandboxes to concentrate on powerful, no-frills and - most importantly - free protection for your PC. The result is a tremendously easy to use and navigate bit of software that does an effective job of keeping you protected from viruses.

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. Marketing itself as "business-grade security", Sophos Home does a little more than most free antivirus software, and actually seems better suited to families.

You get standard virus protection and anti-malware protection, along with browser tools like anti-phishing and, most importantly, content control. Combined with central management of up to 10 PCs, this means you can effectively lock down your kids' browsing options. Although Sophos Home has always had desktop notifications, there was no premium version of the software for it to encourage an upgrade to.

That changed in February with the launch of Sophos Home Premium. Review and where to download: Sophos Home. Each entry in this list has been carefully chosen for its business features, such as remote installation and central management.

The best business antivirus software will have enterprise-level protection against threats, but that doesn't mean they have to cost a lot of money, either.

The price per installation can sometimes be cheaper than even our recommended best antivirus packages. However, we still think Kaspersky software is perfectly safe for home users. We've seen no evidence to convince us otherwise. Kaspersky researchers are well respected throughout the antivirus industry, and the company has publicly exposed Russian cyberespionage campaigns as well as those from the United States and other countries around the world.
