As mentioned in the CB, I have 20 Cygwin Perl libraries that are reported to have this virus. under Cygwin I'm back at perl 5.8.2, and the Encode modules are joined by File::Glob, Sys::Syslog, and several Win32 modules on my system.

My virus database is 269.11.10/943, released on 2007-08-08 so that may account for part of the differences.

I ran a full scan on the 8th (before the update to this virus database) and had a clean bill of health from AVG at that time.

This sure seems to be some false positive.

Update: I stopped scanning, restored my 20 libraries from the Virus Vault to the filesystem, deleted the files from the Virus Vault, did a manual update check, and scanned c:\cygwin\lib\perl5 specifically. The results give a clean bill of health. My new virus database is 269.11.11/944 and my new version of AVG (didn't check old one) is 7.5.476 Free Edition.
