And the package performed very well, blocking 99.8% of threats over a total of five tests and coming third out of a field 18, just a fraction behind F-Secure and Trend Micro. This covers general malware rather than ransomware, but it's still a useful indication of Bitdefender's abilities. To round off our tests, we took a look at the AV-Comparatives' Real-World Protection Test summary for February to June 2018. Bitdefender Antivirus Plus 2019 claimed to have blocked it, though, and when we tried running the program again, it only managed to encrypt two files before it was closed, and even those were restored immediately. We noticed that our test malware hadn't been removed, which initially seemed like a problem. Presumably you could also run into trouble if there's not enough space on the drive for Bitdefender to restore your originals. That might be handy if Bitdefender couldn't restore the original content, but otherwise it leaves you with some cleanup work to do. All the encrypted versions created by the ransomware had been left untouched. That's great, but there was a small downside. We checked our test data, and Bitdefender was right: all our original files were intact. Eventually, our simulator program disappeared, Bitdefender restored our lost files and warned us that an attack had been 'remediated'. We launched our test malware, and watched as it ran for several seconds, making heavy use of the hard drive. To make life more difficult, we created a ransomware simulator of our own – brand-new code which Bitdefender would never have seen before. This wasn't a great surprise, as Crysis is a well-known threat, and any decent antivirus tool should be able to kill it on sight. The program worked perfectly, kicking in before the malware could touch a single one of our files. We began by pitting Bitdefender Antivirus Plus 2019 against real-world ransomware in the shape of a Crysis variant. That's why we set out to determine a product's abilities by running some tests of our own. We’ve highlighted the best antivirus software you can buy todayĪll antivirus companies make big claims about the accuracy of their products, but it's usually very difficult to separate facts from marketing spin. There are no other ransomware-related settings to explore, but Bitdefender does provide an Exceptions list, where you can add known safe applications which Antivirus Plus might block from altering your files. It only takes a click to turn on Ransomware Remediation, fortunately. This appears to be because the module could block innocent apps if they seem to engage in ransomware-like behavior.
