Computer viruses spread by e-mail are growing more sophisticated as virus writers and “spammers” are thought to be joining forces in an effort to make smarter bugs, a computer security group said on Tuesday.
New York-based MessageLabs, which scans client e-mails for viruses to block, said it picked apart some 5.6 billion e-mails from January to June this year and found 1-in-12 contained some sort of virus that penetrated firewalls meant to block them.
MessageLabs typically scans about 50 million customer e-mails daily, and its customers include major government and corporate entities from the British government to The Bank Of New York and Japanese technology giant Fujitsu Ltd.
While the number of e-mails sent globally was not covered by the study, the problem of computer viruses can be massive. They can overload computers with messages, automatically reboot systems and sometimes disable them.
