Trend Micro has become the latest antivirus company to offer extra services to users over the millennium period.
The company has set up a year 2000 virus Web site (pictured) aimed at helping users determine whether there will be increased risk from viruses during the holiday season.
There is a section on 'truth vs hype' which gives users an overview of what to worry about and how much to worry about it.
Trend Micro said one widely under-rated area of concern is what will happen when old data invades computer systems.
Although applications may be secure, the company said, non-year 2000-compliant data in existing databases may contain errors that could cause calculations to stop.
The company said it has added 50 virus doctors and technical support personnel to its usual staff to cover any problems over the new year period.
Also last week, Internet company Star launched a service that will put its customer's email in quarantine over the period to spare IT managers the worry of virus infection.
A chief researcher at Symantec said there could be up to 200,000 new viruses written especially for the millennium.
GartnerGroup claimed that US law enforcement and intelligence agencies have received more than 30,000 threats from virus writers and hackers planning to turn the celebrations into commiserations.
But not all antivirus vendors are beating their chests over their millennium offerings. Graham Cluley, senior technology consultant at rival company Sophos, has hit out at what he describes as "hype".
"There will almost certainly be viruses written deliberately to trigger on New Year's Day, but their threat is no greater than that of any of the other tens of thousands of viruses in existence," he said.
