ZDnet reported:
The Internet community will not know the scale of the February attack until it occurs. It depends on how many hosts are infected.
...
At the moment it's just sitting there quietly, and we won't know how many home users have been infected until Feb. 3.


A virus named Nyxem.E has infected some 300,000 systems, according to a Lurhq analysis of logs from a Web site statistic counter that the worm uses to keep track of its spread. It has a dangerous payload. If the date is equal to 3 (3rd of February, 3rd of March, etc) and the worm's UPDATE.EXE file is run, it destroys files with extensions *.doc, *.xls, *.mdb, *.mde, *.ppt, *.pps, *.zip, *.rar, *.pdf, *.psd, *.dmp on all available drives according to F-Secure.

F-Secure provides an utility called F-Force to clean Nyxem.e infection from a computer.
