Does someone know, if any virus scanner does not like the lazarus-0.9.28.2-fpc-2.2.4-win32.exe

On freepascal.ru forum, there are at least two messages, one mentioning this file and Kaspersky tool, another one mentioning FPC installer and Nod32 tool.

In general, once any antivirus detects some file, you can be sure that within a couple of weeks every other antivirus will start detecting that file, too.

Sergei

this is generally due to crappy signatures... i have stuff that gets detected as virus when it is simply a line in an email with no other code... this is especially bad on the security (IDS/IPS) lists i participate in...

:( Right, max. file size is 20 MB, so nobody can send the whole packet. The only one solution is to send it recompressed in ZIP removing .pas, .inc and other non-virus wise files. But if the problem is in the bundle exe there is no way to check it in VirusTotal.

I'll try to create 2 zips, one with executable files inside and other with dlls, or other non directly executable like html, and send them to virustotal.

Best regards, Jos?

Yes, you are right. Anyway in order to stay in the safe side I had compressed a zip with all "executable" files, like bat, exe, dll, etc.. in a single ZIP file and I'm currently submitting it to virustotal... I have to way a few minutes to get the results (my upload is quite slow)... Problem is that the "suspicious" does not show the offending file/s but seems that they are the UPX packed ones.
