Hi Dan,
thanks for your quick reply.
I thought of something like that.
I tried an update of AVG and a restart but the warning still showed up when unzipping the file.
Only after putting the Blackhole installer file on AVG's exceptions list (while it still tried to prevent that)
it finally stopped bugging.
I hope it will be fine now. I haven't tried to install the plugin, yet…
Cheers anyway!
