So be careful
|Computer security firms are bracing themselves as the moment approaches when the Nyxem virus will strike.
On 3 February the bug will start erasing Word documents, spreadsheets and other common files on infected PCs.
Compromised machines will also be used as launch platforms to help the virus seek out fresh victims.
Because the virus is known to be lurking on more than 300,000 PCs, this scanning could generate large amounts of net traffic as it activates.
The Nyxem-E virus first emerged on 16 January and since then has steadily been racking up victims.
A website associated with the virus has been keeping count of the machines it has managed to infect and now this counter stands at more than 300,000 victims.
Unlike many other recent Windows viruses, Nyxem-E has been built to delete many popular types of file. Security firms suggest that it was written to target businesses because many of the file types it deletes, spreadsheets and presentations, are more common in firms than homes.
However, because many companies have good security systems in place home users are more likely to be caught out. The virus only affects Windows users who must open an infected attachment on an e-mail message to fall victim.
NYXEM FILE TARGETS
DMP - Oracle files
DOC - Word document
MDB - Microsoft Access
MDE - Microsoft Access/Office
PDF - Adobe Acrobat
PPS - PowerPoint slideshow
PPT - PowerPoint
PSD - Photoshop
RAR - Compressed archive
XLS - Excel spreadsheet
ZIP - Compressed file
The creators of the virus have tried to trick people into opening the attachments by falsely claiming they contain a variety of pornographic images or videos.
Security firm Lurhq has analysed the data sent to the website counting victims and found that most are in Peru, Turkey and India. Many other nations are reporting infected machines too.
Some unlucky users have already fallen victim to Nyxem-E because the clock on their machine is set to the wrong time.
When the virus strikes it will also start scanning local computer networks for other machines to infect. This could cause problems for some users as the data generated swamps net links.
UK net service firm Easynet has started telling customers if they are using an infected computer and urging them to clean it up and remove the bug.
Security firms said users needed to be vigilant but not panic because many other Windows viruses have been far more successful at infecting machines but have not caused significant problems for the net.
Despite the furore over Nyxem-E, Microsoft said it was not planning to update its malicious software removal tools before the date that the virus is set to strike.
Instead, the next version of the tool which is due to be released on 14 February will spot and remove the worm if it finds it on a PC.
In an advisory Microsoft said users should not open unusual attachments from unfamiliar sources.
Nyxem-E is also known as Nyxem-D, Blackworm, MyWife, Kama Sutra, Grew and CME-24 virus.
