AVG AntiVirus for the Mac blocked the PSW.ILSpy threat in
Applications->AVG AntiVirus.app->Contents->Backend->lib->libavgcore.dylib
Should I use "Keep blocking" or "Protect Me"?
And… is AVG infected!!! Mmmm makes me worry about my protection…
Same thing here and I am really frustrated. Went on a support chat and was told to uninstall 2015 and install 2016. Also to come here, where no one has received an answer. I downloaded 2016 and same thing happened. Uninstalled 2016 and downloaded Avast. Avast found no viruses but couldn't scan 27 files, so I'm anxious to know if I have a virus or whether this was a false alarm.
Hi Jan, It is working back to normal today and it is up-to-date. Thank you
Hi Francois and Michelle,
We are sorry this happened. The update containing fix was already released however additional steps needs to be done to make it work.
Please disable the Realtime Protection and then run the update. Once update is completed you can enable Realtime Protection again.
Let me know if this works for you.
Jan
