Russian crime gangs are making millions by flogging counterfeit Tamiflu to paranoid Britons online, it has been claimed.

Anxious residents who fear they may not be able to obtain the drug through the NHS may be lining the pockets of overseas conmen.

Many people may be putting themselves at risk of identity fraud as well as handing over cash for potentially useless drugs.

Graham Cluley, of computer security firm Sophos said: "As more and more cases of swine flu in the UK come to light, it is essential that we all resist the panic-induced temptation to purchase Tamiflu online.

"The criminal gangs working behind the scenes at fake internet pharmacies are putting their customers' health, personal information and credit card details at risk.

"They have no problem breaking the law to promote these websites, so you can be sure they'll have no qualms in exploiting your confidential data or selling you medications which may put your life in danger. If you think you need medication go to your real doctor, and stay away from quacks on the internet."

Research by the firm found organised criminal networks are driving online shoppers to dodgy virtual pharmacies in return for a share of the profits. Investigators believe thousands of fraudsters, mostly based in Russia, work around the clock to promote the illegal goods.

They found the top five countries purchasing Tamiflu and other drugs are the United States, Germany, United Kingdom, Canada and France.

Sophos said crime gangs can earn between £10,000 and £60,000 every day and continuing concerns about swine flu could drive their profits even higher.

A Department of Health spokesman said: "There is no need to jump the queue or pay for antivirals. They are free on the NHS and being offered to all who need them. Anyone who buys medicines from internet sites could be in danger of receiving counterfeit or substandard medicines."
