The annual Norton Cyber Security Insights Report found about 18 per cent respondents from India saying they have at least one unprotected device, leaving their other devices vulnerable to ransomware, malicious websites, zero days and phishing attacks.
About 79 per cent respondents said they know they must actively protect their information online, but they still share passwords and engage in other risky behaviour.
He added that while people are increasingly growing aware of the need to protect their personal information online, they aren't motivated yet to take adequate precautions to stay safe, he added.
"While consumers remain complacent, hackers are refining their skills and adapting their scams to further take advantage of people, making the need for consumers to take some action increasingly important," he said.

About 64 per cent of the respondents admitted that it has become harder to stay safe online over the past five years.
However, millennials exhibit surprisingly slack online security habits and are happy to share passwords that compromise their online safety (34 per cent). Many consumers are still willing to click on links from senders they don't know or open malicious attachments.
"This is likely why they remain the most common victims of cybercrime, with 55 per cent having experienced cybercrime in the past year," the report said.
"Cybercrime isn't going away and consumers must reject complacency to adequately protect themselves. By adopting a few basic behaviours, we can make big strides in mitigating cybercrime risk," Chopra said.
As expected, people who experienced cybercrime within the
past year emerged more likely to be concerned about the security of their home Wi-Fi network -- 79 per cent vs 70 per cent non-victims.
However, the victims were less likely to password protect their home Wi-Fi network than non-victims at 28 per cent vs 10 per cent of non-victims saying they have unprotected networks.
Additionally, when it comes to public Wi-Fi, one in four (27 per cent) regularly use public Wi-Fi connections available at airports, coffee shops, etc, he added.
Despite half the respondents believing they could have their identity stolen after entering account/personal details on public Wi-Fi, they are still willing to engage in actions like answering a survey question (58 per cent), installing a third-party app (35 per cent), provide access to files while online (21 per cent) or even turning off security software (19 per cent), the report said.
He added that users should backup important data regularly, change default passwords on devices like routers and avoid sharing passwords.
