Businesses face a growing threat from malicious code which uses sophisticated technology, known as rootkits, to evade anti-virus software, security analysts claimed last week.

Researchers have demonstrated how hackers can implant rootkits into the Bios memory of a PC, allowing the machine to be continually reinfected, even if the disc has been disinfected of all malicious code.
