More than nine in ten (92 percent) Brits bank online, says McAfee.
Research by the security software firm revealed 16 percent also access their online banking accounts from their mobile phone. However, 81 percent of online bankers admitted recent cybercrime attacks, such as the Sony PlayStation Network security breach that happened earlier this year, have made them more wary of banking on the web.
Just a third of those surveyed said they were "completely confident" their details are secure when accessing online banking while 54 percent said they were more worried about their personal information falling into the wrong hands than they were about losing their job.
Despite this, 54 percent only use basic anti-virus software instead of a comprehensive security suit and shockingly, four percent admit they take no security measures whatsoever when online banking.
Just under a quarter (23 percent) admit to using easy to remember passwords such as pet's name or mother's maiden name, while 16 percent say they write their online banking details on a piece of paper to ensure they can access the service. Furthermore, one in three utilise a password from another web-based account for their online banking.
Nearly six in ten (58 percent) of web users surveyed said they had received a phishing email purporting to be from a bank, while 9 percent say they've had money stolen from their bank account. Nearly half (48 percent) believe it's a bank's responsibility to ensure online banking is safe.
"Most instances of banking fraud are not due to the bank's technology being compromised," said Raj Samani, chief technology officer for McAfee EMEA.
"It's more likely that people are unwittingly giving out their personal banking information to criminals via phishing scams and copycat sites, or their computers being infected with malware."
The security firm advised online bankers to use comprehensive security software, never respond to phishing emails and employ strong never-been-used before passwords in a bid to stay safe.
