Computer Associates Africa together with other anti-virus vendors urges South African companies to take the necessary precautions against a new variant of the Mydoom worm - Win32.Mydoom.B also known as WORM_MYDOOM.B or W32/Mydoom.b.
The characteristics of Mydoom B are similar to the original Mydoom. However, it appears that the worm is not spreading at the rate of Mydoom.A, but CA is monitoring the situation.
Users should be aware that Mydoom B is packed differentially from A - this means the worm is compressed and encrypted in an effort to thwart current anti-virus detection.
CA has again - as in the case of Mydoom A - issued a cleanup utility which can be downloaded at http://www3.ca.com/virusinfo/virus.aspx?ID=38114
The company also urges PC users to download a free one year license of its eTrust EZ Armor anti-virus and firewall desktop security suite. The software is made available through a partner initiative between CA and Microsoft and offers protection for users of Windows XP, Windows 2000, Windows Millennium Edition and Windows 98/Windows NT.
