'JDBGMGR' causing net confusion - Sophos says don't be duped by hoax
Posted on 15 May 2002.
Sophos, a world leader in corporate anti-virus protection, today warned computer users to be sceptical following the latest hoax message about a 'virus' sweeping the internet. Sophos has already received enquiries from thousands of concerned computer users.

The fake warning tells users to search their hard drives for a file called JDBGMGR.EXE. The message also advises users to delete the file because it is infected by a virus which may trigger after 14 days.

But JDBGMGR.EXE is the Microsoft Debugger Registrar for Java and may be present quite legitimately on many computers.

The confusion is compounded by the W32/Magistr-A virus which is capable of emailing infected copies of JDBGMGR.EXE to innocent users. Most anti-virus software has been capable of detecting W32/Magistr-A for over a year.

"If you receive an unsolicited executable file in your email, simply delete the email," said Graham Cluley, senior technology consultant at Sophos Anti-Virus. "This is a confusing hoax, but the message is simple: you should never launch or open unsolicited code on you computer. The best way to check for a virus infection is with anti-virus software. If your anti-virus software is up to date, you will be protected from the Magistr virus anyway."

Sophos reminds users that they should not pass on virus warnings to friends. Instead, check the facts at an anti-virus website, or forward the warning to the person in your company who is responsible for virus protection so they can decide if it is valid.

Sophos offers a free hoax information feed, which enables webmasters to place "always fresh" data about the latest internet myths, as well as real virus threats, on their public websites and company intranets.
