Nope. You must prove, with near 100% certainty, that it is not a false
positive. Right now, you are yelling "trojan", but offer me only 43% confidence
in your assessment — and you aren't even prepared to assert that every one of
the potential false positives relates to identically the same trojan; couple
that with my 0% confidence in any antivirus product — especially any which is
commercially motivated to exploit the naïve — and I must do no more treat this
report with the contempt which any such knee-jerk reaction deserves. It's
entirely your choice how you wish to proceed, but we we are under no obligation
to do anything here.

Ticket details:
When I downloaded MinGW to my new HP laptop running Windows 10, I complied a
2-line Hello World program in C with gcc. Avast reported a Win32:TrojanX-gen
virus. Going to virustotal.com, 31 of 72 antivirus products reported a virus or
similar. Clearly, the problem could not be in my 2-line program, so it must be
in a library.
This problem must be fixed ASAP!
Thank you.

Reply To keith
Should be fixed, in wsl-5.3.2. Dependent applications should be relinked,
with updated libraries.
OK, I updated from installer to 5.3.2. mingwex-3.dll has no problems. this
compiles good with linked dll: gcc -fopenmp omp_hello.c -o omp_hello But now,
with -static addition, compiling fails
f:/mingw/bin/../lib/gcc/mingw32/9.2.0/../../../../mingw32/bin/ld.exe: f:/mingw/
bin/../lib/gcc/mingw32/9.2.0/../../..\libmingwex.a(codeset.o):(.text+0x143):
undefined reference to GetCPInfo@8'
does mingw needs full reinstall to fix this error?

libmingwex-5.3.1 is BUGGY! it imports from self procedure
"__emutls_get_address", while not exporting it. thus any linked app would not

5.2.2, it is good; it has not any "__emutls_get_address" inside;

Comment:
You claim this is likely a false positive, and of course that may be true---but
it also may not be. In the past, my experience has been that reports of a virus
being present are true---but mostly I work on a Mac platform---I'm new to
Windows 10.
How would you propose determining this is a false positive? Guidance would be
appreciated, as I certainly will not run code that has a moderate chance of
being unsafe.
I look forward to constructive suggestions.

Comment:
does mingw needs full reinstall to fix this error?
No, it is a separate issue, (which unfortunately, arises due to the resolution
of this one). I didn't notice it, because once libmingwex.dll.a is installed
into GCC's library path, it does seem to arise only when -static is explicitly
specified, and that's not something I do routinely. However, if
libmingw32ex.dll.a is not installed, it may become problematic anyway.
The final solution seems to be to add an extra scan of -lmingw32 -lmingwex into
the GCC *libgcc spec sequence. Unfortunately, that requires a GCC rebuild, to
fix properly, and that isn't a quick fix. As an interim workaround, assuming
that you are using GCC-9.2.0, and that you don't already have a custom GCC
specs file, you may drop the attached modified GCC-9.2.0 specs file into
$MINGW_ROOT/lib/gcc/mingw32/9.2.0/. (If you already have a customized specs
file, you will need to edit it, to add the additional -lmingw32 -lmingwex
references into the *libgcc specs string. In any case, you will need to adjust
$MINGW_ROOT to match whatever drive and directory prefix you've used for your
MinGW installation).
