Of those who have suffered an attack, 39% described the assault as causing a “major disruption” to their system whilst a further 10% described their attack as “deadly”, rendering their computer unusable.

One in twenty claimed that personal information had been stolen as a result of a malicious attack.

Young males were the most likely group to be victim to a malicious attack, with 38% of those under 20 and 30% of under-20s admitting to experiencing virus problems on their computers.
