AVs and False Positives

Today we received 2 different support requests from users informing that their Antivirus software identified IW14.2.8.exe as a virus/trojan. Among the AV software we find Kapersky, Zone Alarm, Windows Defender and Symantec.

Kaspersky is famous for its heuristic engine false positives, specially against binaries compiled by any Delphi version. Zone Alarm shares the same engine so whenever Kaspersky reports something, Zone Alarm will do the same. (Un)Fortunately, Delphi is one of the few native programming languages left and that’s why it is used by many virus creators. Tongue

We have this issue from time to time, and not only with IntraWeb but CrossTalk as well. Basically, using Delphi makes the chances of any EXE being flagged as a virus higher because the AV engines rely a lot on heuristics. And since so many viruses are written in Delphi, they “learn” the signature of Delphi created EXEs in many cases rather than the virus itself.

We have reported the false positives to Microsoft and Symantec. We already have Symantec response, confirming that the report is a false positive, as follows:
