Those who suspect they might be a victim of this bug will find a message saying that your Norton 2006 product "does not support the repair feature". This appears after you run LiveUpdate or restart your computer.
According to a report in the Washington Post one of its readers spotted that something was suspicious when the same message cropped up on both his desktop PC and his laptop.
Rather than waste time re-installing the software, the reader just ignored the warning message and carried on. Naturally he also reported the problem to Symantec.
The company has issued a fix here. All you do is run Symantec LiveUpdate and with any luck it should make the warning message disappear. µ
