The Kama Sutra worm, designed to begin deleting files on infected computers this morning, has caused virtually no damage, according to antivirus firms.
The worm, also known as Nyxem.E, MyWife and Blackworm, has been circulating for a couple of weeks and antivirus vendors say enterprises have done well to ensure their networks were protected against the pest.
"[There have been] no reports of any W32/Nyxem-D detonations so far. Also, the virus seems to be dropping in e-mail prevalence. It was down to second place yesterday, according to our monitoring stations, and slid again into third place today," Paul Ducklin, head of Technology at Sophos Asia-Pacific, told ZDNet Australia.
The worm's ranking was overtaken by MyDoom and Netsky variants, which have been around for a number of years.
"It seems reasonable to assume that Nyxem [Kama Sutra] isn't going to be the disaster that some local speculation may have suggested," Ducklin added.
McAfee Asia-Pacific shared Ducklin's view. "No local outbreaks reported and very few reports of infections. Most companies are seeing the virus at the gateway but not in large numbers -- typically a few hundred viruses are blocked," its marketing director, Allan Bell, said.
