Concerns over MacBook Security
I visited a website and it installed a version of Adobe Flash onto my Mac. It prompted me from my administrator password, but I didn't enter it. Am I safe from the adware? I ran several scans, deleted the files from Downloads, and found nothing. However, my Mac has shown bizarre software glitches recently. Im not sure if this is due to Mojave or potential adware.
The glitches include:
1) A momentary flash while the progress bar loads following boot up (apparently other users have the same issues)
2) Files not appearing instantly (they slide into screen)
3) Dock hanging for a few seconds after shutting down computer (occasionally doesn't do this)
I contacted Apple Support and was told the "Dock issue" is most likely a normal shut down sequence, but Im not sure if this is the case.
