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.
