The Computer Virus Prevalence Survey found that last year, almost a third of the hundreds of businesses polled worldwide had suffered a virus “disaster,” defined as 25 or more computers infected by a single virus in the same incident.
The report was released on Friday by the ICSA Labs subsidiary of security firm TruSecure. The survey polled 300 randomly selected companies and found that 92 had had major virus incidents in 2003, up from 80 in the year before. Almost all of the companies surveyed said that at least 90 percent of their desktops have antivirus protection, but still a third of the companies suffered virus disasters.
The servers had to be taken down for an average of 17 hours as a result, the report said.
