Cybercrime will cost the UK economy some £1.9bn this year, says Symantec.
According to the security firm, this equate to £103 for every person affected.
As a result, Symantec has launched the Norton Cybercrime Index, a tool designed to alert web users to the most dangerous sites and search terms, as well as the most popular scams, spam emails and ways criminals commit ID fraud.
The index, which can be viewed online, from mobile devices or within Version 5.0 of Norton 360 - Symantec's latest security suite, also launched today - generates a number based on how high the day's internet security threat level. Symantec said the number is calculated using an algorithm that uses data from Symantec's Global Intelligence Network, which monitors more than 130 million servers worldwide to keep track of new threats and attacks, along with data from consumer risk management firm ID Analytics, and DataLossDB, a research project from the Open Security Foundation.
As well as checking its Cybercrime Index everyday, Symantec advised web users to use strong passwords on a regular basis, be wary of the personal information they post on social networks and protect their PC.
The latest version of Symantec's security suite Norton 360 features a new user interface that gives consumers a snapshot of security controls, settings and information about the PC's protection and performance status. From here, users can also access the Norton Cybercrime Index and Norton Safe Web - the security firm's URL-checking service. Norton Safe Web now includes the Norton Secured badge to identify businesses that use VeriSign SSL Certificates or have the VeriSign Trust Seal on their websites, alerting consumers to the fact that transactions on these sites will be secure.
The PC Tuneup tool included with the security suite now features a faster registry cleaner that fine-tunes key system settings and frees up memory so applications start up and run more quickly, while the Automated Backup has been speeded up.
"Consumers need more protection than ever as cybercriminals target every aspect of our increasingly digital lives," said Janice Chaffin, group president, Consumer Business Unit, Symantec.
"We've designed the latest version of Norton 360 to give consumers an easy-to-use, all-in-one suite that provides the utmost protection and won't slow down their PC."
Norton 360 Version 5.0 is available through Symantec's website now, as well as through high-street retailers. The security software is priced at £59.99 for a three PC Licence and 2GB of online storage space. Alternatively, the premium edition that comes with 25GB of online space costs £69.99.
