Fans of Jamie Oliver have been hit by a computer virus after visiting the TV chefs site, according to news reports.
Those visiting the site while running older versions of Adobe Flash, Java and Microsoft Silverlight are most likely to have been infected.
Victims were redirected to a WordPress site which attempts to download the damaging software on their computers.
Compromised machines will see their searches hijacked and will be redirected to other harmful sites.
The website is ranked 519th in the UK, and receives around 10 million hits every month.
Such breaches usually only happen when login credentials to a website are stolen, or a vulnerable website plugin is compromised.
The issue appeared to have been fixed as of Wednesday morning.
