Avast false positive was wrecking havoc on the developers when we caught up with it. Avast has started detecting all the binaries created with Delphi as malware. Those developers working on Delphi apps were the first to encounter the anomaly. Initially this looked like an isolated incident, but gradually spread like wild fire. Avast's user forum was flooded with threads of revelations on Avast false positives drawing a broader picture of the scene. It seems a sort of thing like SNAFU that hit iTunes a few months ago. It disturbed iTunes after an update. The problem was quickly fixed, and it was the same for Avast.In case, you are one of the victims of Win32:Delf-MZG false positive, go for manual update and check to see the new bits are available. As of now, we could see on the Avast!web forum - Win32:Delf-MZG false positive was fixed in the latest VPS - 091203-1 for the update.
