The results show that an alarmingly high proportion of users did not know what software was running on their computers to ensure they had adequate protection from hackers, malware, viruses, ‘dirty’ websites, and other online threats. More than one-tenth of respondents (13%) said they did not have any anti-virus software installed on their machines at all, while a further 9% did not know if anti-virus was installed. Almost one-fifth of respondents (19%) did not know if they had firewalls installed.
