A fifth of IT managers say they have seen more than a 100% increase in spam, and that user computers had been affected by an average total of 30 virus incidents over the past year.
Network management firm Ipswitch questioned 460 IT managers about their security over the year, and found that 20% reported more than a 100% annual increase in spam on their organisations' e-mail servers.
Overall, 76% of IT managers reported some sort of increase in spam volumes. In addition, 27% of those surveyed reported receiving complaints from e-mail users about spam on a daily basis, and 25% reported receiving complaints on a weekly basis.
Regarding the number of incidents of viruses and malware installed on e-mail users' computers, IT managers said there were an average of 30 infections of viruses, worms or Trojans over the past 12 months, and 22 incidents of spyware or key logger installations over the same period.
The total cost of defending against these threats averaged more than £6,500 a year, when factoring in the costs of technology, staff, recovery, remediation and end-user training.
At the same time, respondents said that the total annual cost of damages caused by e-mail-related events, including lost productivity, staff time, and fines related to compliance regulations, averaged £2,800.
Small to mid-size organisations spent 40% less than average, while sustaining similar annual losses due to e-mail events.
