A worm that spreads through low security networks, memory sticks, and PCs without the latest security updates is posing a growing threat to users.
The malicious program, known as Conficker, Downadup, or Kido was first discovered in October 2008.
Although Microsoft released a patch, it has gone on to infect 3.5m machines.
Experts warn this figure could be far higher and say users should have up-to-date anti-virus software and install Microsoft’s MS08-067 patch.
Most malware uses one of a handful of sites to download files from, making them fairly easy to locate, target, and shut down.
But Conficker does things differently.
Anti-virus firm F-Secure says that the worm uses a complicated algorithm to generate hundreds of different domain names every day, such as mphtfrxs.net, imctaef.cc, and hcweu.org.
