TelstraClear plans to launch server-based anti-virus software in the next few months, but probably not until the new year.
Public affairs manager Mathew Bolland says the company is working through pricing issues, including whether to charge for the product.
The country's largest ISP, Xtra, introduced server-based anti-virus software from vendor Trend Micro in July and built the cost of the service, estimated at around $1 million, into the ISP's existing cost structure. Ihug, which also uses a Trend Micro server-based solution, charges customers $2.50 a month for the service.
Bolland says TelstraClear's ISP rates are "already competitive" with Xtra's.
"We're not making any announcement yet as to who the vendor is either - it's still early days."
Trend Micro was reportedly in New Zealand for talks with TelstraClear in July, however Bolland has no comment on that.
Xtra reports that it blocks around 40,000 viruses a day on its servers - a total of around 4.5 million since the service was launched in July, according to spokesman Matt Bostwick.
