running current (updated) freeav (avira) and try compile

reference/FileSelPreview with
GUI MT, MSC9, all static, without BLITZ

--> false positive: TR/Crypt.XPACK.Gen2.

compile withouth MT or in DEBUG does not yield the false positive.. i suppose its only MSC9 problem. didnt try with mingw though.

traced it down to be FileSel the problem. (make new empty CtrlLib project, GUI MT, put a FileSel in the app class, compile like above. thats all).

what can be done with it?

It sucks, but obviously, it is not FileSel problem, but freeave (avira) problem....

Maybe you should let them know, with exact steps to reproduce the problem?

yea, i know it's AV business. upp is out of guilty here. but FileSel was the part causing the false positive.

i really ask my self if they will care about this, upp is too small yet.. but ill do.. will send them an exe example so they can analyze it..

EDIT: just phoned avira. this is really bad, they only fix it for compiled exes. not generally, so that upp in general could profit from it. i'll try it anyway..am in contact with them..

Hm, in theory, I would say that perhaps the code that is fetching icons from the system could be the culprit.... Maybe it would be worth to try to exlude it?

I bet you can. Comment out content of

virtual Image FileIconMaker::Make() const {
/* */
return Null;
}

i found the reason why it's ringing a false positive:

NetNode.cpp
::WNetOpenEnum()
::WNetOpenRessource()

as soon as one of theese is present, boom...

but it's a problem, quite a huge one. theese are Windows Functions. we can't change the code in any way.

i'll try to contact avira again.

it's a month now and i havent heared anything from these guys over at antivir. no changes arrived with any updates, though i have sent them some example exes that trigger the error as well.

so any of those WNet* functions in NetNode are triggering the fals e positive. is there a possible workaround for that?

has any of you guys experienced the same problems? (with free av for windows)
