Controlled tests carried out by the security vendor showed that even with Windows Defender activated a portion of malware threats were able to get through.
"As a means of protecting a computer from viruses, data theft and other type of malware, Windows Defender is better than nothing," said Catalin Cosoi, chief security strategist at Bitdefender.
"But it;s not a whole lot better. Most of the popular antivirus systems can do better. The conclusion is clear: using your PC without a security solution is extremely risky," he added.
That conclusion will be positive news for the antivirus vendor community and their resellers and Bitdefender is urging those early adopters of the latest Microsoft OS to get additional protection quickly.
