An IRC worm is usually a standalone program that uses IRC networks to spread itself by establishing a connection to an IRC server or by dropping specific scripts to an IRC client directory.
IRC-Worm/Generic is a heuristic detection and a name provided to possible new IRC
variants of malware. AVG uses heuristic detection heuristic detection
which is the ability of an anti-virus program to detect new viruses before the vendor can get samples and update the program's definitions for detection. Heuristics uses non-specific detection methods to find new or unknown malware which allows the anti-virus to detect and stop if before doing any harm to your system. The techniques involves inspecting the code in a file to see if it contains virus-like characteristics. If the number of these characteristics/instructions exceeds a pre-defined threshold, the file is flagged as a possible virus
to using heuristics is that it is not as reliable as signature-based detection (blacklisting) and can potentially increase the chances that a non-malicious program is flagged as malicious. With heuristics, there is always a potential risk
for a "False Positive
" when the heuristic analysis flags a file as suspicious
that contains no malware. Reducing the detection sensitivity will minimize the risk but then that increases the possibility for new malware to infect your system.

rdsok, Moderator at the AVG forum has instructions for suspected FP's.
If you suspect a file to be a false positive. Test the file at [virusscan.jotti.org] and if it is a false positive, archive (zip, arc, tar etc) the file using a password and email a copy to firstname.lastname@example.org with a brief description as well as the password you used to archive it with.
If it is a false positive , turn off hueristic scanning for the time being. When Grisoft adjusts the virus defintions you can turn it back on. If turning off Hueristics still doesn't allow access to the file while testing and emailing... disable the resident shield temporarily.
