Does Nod32 Have A Problem Winrar?

[pmcx9]

I have installed nod32 as several learned contributors to this forum have said it rocks. I have run NAV no problem for years

It has just shredded my unattended files as it doesn't seem to like my self extracting winrar files. It says there is a win32/irc.sdbot.ec trojan present in these files.

Any one else having this problem? or have I really got a virus after all?
