Security experts are warning about a stealthy Windows virus that steals login details for online bank accounts.
In the last month, the malicious program has racked up about 5,000 victims - most of whom are in Europe.
Many are falling victim via booby-trapped websites that use vulnerabilities in Microsoft's browser to install the attack code.
Experts say the virus is dangerous because it buries itself deep inside Windows to avoid detection.
Old tricks
The malicious program is a type of virus known as a rootkit and it tries to overwrite part of a computer's hard drive called the Master Boot Record (MBR).
This is where a computer looks when it is switched on for information about the operating system it will be running.
"If you can control the MBR, you can control the operating system and therefore the computer it resides on," wrote Elia Florio on security company Symantec's blog.
Mr Florio pointed out that many viruses dating from the days before Windows used the Master Boot Record to get a grip on a computer.
Once installed the virus, dubbed Mebroot by Symantec, usually downloads other malicious programs, such as keyloggers, to do the work of stealing confidential information.
Most of these associated programs lie in wait on a machine until its owner logs in to the online banking systems of one of more than 900 financial institutions. http://news.bbc.co.uk/1/hi/technology/7183008.stm
