At first glance, I'd guess that it's VirtualProtectEx
Finally you've been right.
I moved to previous release where i can see 12 virus errors with VirtualProtectEx and 2 wothout it.
What if just remove that call?
At least, some other soft works fine without it...
Updated loader to not cause false-positives, updated installers for 4.4.2, didn't increase version...
