Nearly a third of business workers surveyed felt that system administrators were to blame for the Conficker outbreak, anti-virus firm Sophos has revealed.
Thirty percent of the 160 people polled said system administrators should shoulder the blame for the recent Conficker worm outbreak because they were too slow to roll out a Microsoft security patch.
Microsoft was also blamed by 17 percent of respondents, who said it was the vendor's fault for having the security hole in its software in the first place.
Just over half of all respondents (53 percent) hold the virus writers responsible for the worm which takes advantage of the flaw.
"What is most surprising is that so many technical people blame their peers for not doing a better job of defending their networks," said Graham Cluley, senior technology consultant at Sophos.
"Many companies appear to be incredibly frustrated by the constant need to roll-out emergency patches across their networks. Worryingly for Microsoft, one in five people's anger is aimed in their direction for having the software flaw in the first place."
The Conficker or Downadup worm has struck businesses hard across the globe in the last week. The worm spread via a security hole in Windows system, cracking poorly-chosen passwords and also infecting via USB sticks.
Microsoft released an emergency security patch which can help prevent the Conficker worm from infecting Windows systems in late October 2008.
