Kaspersky Internet Security (£17.49 UK/$39.99 US) is our top choice among midrange packages. But it's beaten by Bitdefender Antivirus Plus, which has even more features. The entry-level program, Kaspersky Anti-Virus (starting at £12.49 UK/$29.99 US), has dedicated ransomware protection, a virtual keyboard and a convenient online account portal. Kaspersky's Windows products have excellent malware-detection scores and a light-to-moderate system-performance impact, the two most important criteria in our rankings. Read our full Bitdefender Antivirus Plus review. The midrange Bitdefender Internet Security adds parental controls, webcam protection and a two-way firewall, while Bitdefender Total Security tops off the lineup with an anti-theft feature for laptops, a system optimizer and licenses for Bitdefender Antivirus for Mac and Bitdefender Mobile Security for Android.Ī fourth product, Bitdefender Premium Security, is basically Total Security with unlimited VPN usage, a cross-platform password manager and priority tech support.īut the best deal is the Bitdefender Family Pack, which puts Total Security on up to 15 devices for (a frequently discounted) $120 per year. It also offers the most value, with an unlimited (but Windows-only) password manager, a secure browser with a virtual keyboard, a Wi-Fi network scanner, a file shredder, protection against encrypting ransomware and Bitdefender's web-privacy software - features often found only with pricier antivirus packages.

Regardless of the edition you own, you should know that the BitDefender Virus Definition packages should work with Bitdefender Antivirus Plus, Bitdefender Internet Security, and Bitdefender Total Security.Bitdefender Antivirus Plus is our top choice among entry-level antivirus products. There are definition packages for various editions of Bitdefender products, from the latest (2016 / 2015) going back to version 7, almost each with dedicated x86 and 圆4 setup files. After hitting a few 'Next' buttons in the setup wizard, your Bitdefender product will have all the latest definitions installed. The definitions installer must be transfered to the offline computer using any portable storage media and launched just like a regular application. To install the virus definitions, you must download the package that matches your operating system's architecture (x86 or 圆4), while also making sure you are grabbing the correct edition. In this case, you can use the latest BitDefender Virus Definitions package to make sure the virus signatures are up-to-date. Nevertheless, there might be situations when your computer gets disconnected from the Internet, and the automatic download is not possible anymore. It is recommended that you allow your Bitdefender product to automatically scan for new definitions and update its database silently. The virus signatures are normally downloaded and installed automatically by the Bitdefender product you own. Aside from virus signatures, these include spam signatures, which add new filters and rules for the antispam engine in Bitdefender products. The ever-growing number and the complex nature of threats make Bitdefender and other security companies release virus signatures almost daily. ![]() Having the latest virus definitions installed enables you to make sure your antivirus recognizes the latest threats, blocks their actions and sends them to the quarantine before the system is compromised. ![]() It's needless to say how important is to keep your Bitdefender (and not only) security software up-to-date. ![]()
