Small businesses are exposing themselves to hackers and viruses because they are unaware of the risk posed by a flaw in Microsoft's Windows operating system.
Earlier in February, the software giant urged users to update security using patches available free of charge on its website www.microsoft.com/uk
The warning came as a survey suggested that attacks on small business websites had spiralled by ten times the normal rate.
The MyDoom worm, the latest and some say most vigorous example of malicious code to hit businesses, reached one million infections in its first day.
But secure internet specialist IntY says a large number of businesses do not think they are at risk, simply because they have fewer computers than larger companies.
It means many small businesses are unresponsive to warnings like the one issued by Microsoft.
