I was trying to install the app "Moo0 File Shredder", which I have had previously installed on my system and MWB had never flagged it as suspicious. Yesterday when I tried to install it, MWB was blocking the exe from running, but it did not give me an option either to accept, ignore, or block it altogether it the event I suspected it was suspicious. I tried to exclude it under the "Exclusions" option, but it would still get blocked.
MWB pop-up did mention the app was trying to connect to the internet and provided the website link & IP address claiming the site was malicious. (bin.moo0.com - P 126.96.36.199). The file itself was scanned with multiple other scanners and all showed up clean.
I have been using this app or a very long time & from what I can see Moo0 thrid party apps and not flagged as suspicious on the internet with multiple download sites, though one can never be 100% certain I guess.
Anyway the way I got around this was to momentarily deactivate the my connection to the internet, install the app and re-connect, though I don't know why MWB does not give you an option anymore to accept, ignore or block a file or website there on the spot.
Thanks for you reply and help
