Microsoft said on Thursday that files on one of its Web servers had been infected by a virus, and could have been downloaded by customers of its corporate support services in the U.S.
"Microsoft received notification of some infected files on a private access Website for Premier Support and Microsoft Gold Certified Partners in the U.S. only," a Microsoft spokesperson said.
Microsoft's Premier Support service provides updates and bug fixes to customers in the U.S. and access to the Web site is protected by password, according to a Caroline Lee, a spokeswoman at Microsoft's U.K. office. Customers do not get files sent out to them automatically, but have to log on to the site and download them themselves, said Lee.
"As soon as the problem was reported, it was dealt with speedily and has now been resolved. We are not aware of any problems encountered by our customers as a result of this issue, and this is not an issue for our customers in the U.K.," the spokesperson said.
