The destructive "NakedWife" Trojan worm that hit the Net Tuesday did not spread far. The impact was minor and only computers in North America and Europe were hit.
"Compared to the Anna Kournikova and I Love You viruses this worm did not get anywhere at all," said André Post, senior researcher at Symantec's Antivirus Research Center (SARC). "If I have to make an educated guess, I would say a few thousand computers were infected."
First reports on the worm came in at around 10:00 AM EST Tuesday. By the end of the workday on the US East Coast the spread of the virus had stopped, said Post.
"Quick acting on our side doesn't guarantee anything if users don't react. Wide spreading was also prevented by the increased virus awareness amongst customers," said Post, adding that wide media coverage also contributed.
SARC received "about 40" reports from customers with infected systems, most of which were in the US, a few in Canada and a few in Europe.
McAfee, a division of Network Associates, reports lower numbers with 15 customers hit in North America and three in Europe. Asia, it seems, wasn't hit at all.
"Asian businesses had already closed for the day when the worm surfaced. When they opened on Wednesday the worm had been dealt with," said Post.
Both McAfee and SARC said NakedWife most likely was created in South America.
Most anti-virus software vendors have updated virus definition files available that can discover and eliminate NakedWife.
