Sophos Anti-Virus came under attack from a leading European telco last week for stating mobile phone viruses have been greatly exaggerated.
Sophos managing director Richard Baldry said WAP phones are simply not powerful enough yet to be infected by viruses.
This followed a hoax virus message being distributed around the world via e-mail and appearing on mobile phone screens. The hoax text, which displays "Unavailable", falsely refers to Sophos in an attempt to be credible.
Baldry's statement drew an angry response from Aaron Sault, business process design manager of T-Motion, a division of Deutsche Telekom, who labelled the WAP statement as 'naive'.
Sault said the WAP network is almost as prone to viruses as the Web network but WAP portal managers have greater control over content and application integrity.
