Computers are less susceptible to viruses and other threats than many users might think, according to consumer watchdog Which?.
The survey found that not one of five computers connected to the internet for four weeks became infected, despite figures suggesting 60,000 new malware threats occurred daily.
Each machine was used to visit 22 “reputable” websites, ranging from Amazon.com to Tesco.com, for an hour a day.
A Which? survey in October found 57% worried about threats.
