The UK is among the top 10 western European countries for sending malicious spam, according to the latest threat report from Trend Micro.
The report found that 9.77 per cent of spam messages originate in the UK. The most frequently sent type of message is commercial or advertising spam offering work from home schemes or weight loss treatments, for example.
Weight loss offers account for a quarter of all scam mails, while 'business opportunities' account for around a third.
"The research shows that, despite media reports about the rise in other online threats, traditional spam techniques are still favoured by cyber criminals," said Rik Ferguson, senior security advisor at Trend Micro.
"Consumers continue to fall prey to these types of scam, and that's why they continue to be popular. My advice would be, if it looks too good to be true, it probably is."
The research has been released during Get Safe Online Week in the UK which seeks to increase awareness about online risks.
"It is vital that we make people aware of the threats and how to deal with them, to ensure they continue to use the internet safely and confidently," said Tony Neate, managing director of Get Safe Online in the UK.
"It is about education and making people aware that these dangers are real but that, armed with the right knowledge, we can all continue to enjoy using the internet securely."
Trend Micro has made a number of recommendations designed to help people stay safe online, including questioning the validity or source of emails and their attachments.
While these may appear to come from friends, family or colleagues, they could still be carrying malicious attachments, the firm warned.
Workers should be on their guard with messages that claim to be from sof tware vendors or the IT department. Trend Micro said that any email that creates doubt should be followed up by a visit to the sender's web site or physical location.
People should also look out for emails that ask for personal information, even what looks like a legitimate email from the IT department asking for a password.
