Rightly or wrongly, enterprises believe they are more secure than they were a year ago, and their efforts to stop malware are slacking off. That’s one of the findings from a new study scheduled to be published next week by BT, which conducted the research as a follow-up to its 2005 study on malicious code. The study found that the number of companies which consider malware to be a high priority has dropped since 2005, from 62 percent to 54 percent. A third of companies say “only a modest effort” is being spent to combat it, and 14 percent say they are doing little or nothing about the malicious code problem.
