[Access Denied - Can't install malwarebytes]

Thanks, treed.  Yeah it was obviously a scam, so of course I didn't respond as instructed by the nefarious pop up.  Thank you for the link, I'm sure that would have been a much less time consuming fix than what I ended up doing.  After so much time wasted on this, I ended up doing a full Time Machine restore, from the day before Safari got corrupted.  Not pretty, but effective!

UPDATE:

 

I created a new user account, logged into it, and Safari works just fine.  However, when I log back into the main account, Safari is still corrupted

Thanks.  I got MB installed and did a scan.  It said found some malware, and needed to reboot to completely remove, so I rebooted.

 

Unfortunately, my Safari is sill corrupted.  When I open it, I get a couple popups with the following message

 

 

From "apple-error-report.com":

Any suggestions?

Unable to install on a Mac running 10.10.4

 

Ok, Safari on this Mac I'm working on is totally polluted w/ malware, lots of popups, unusable

 

So I downloaded Malwarebytes for Mac on a PC, copied to a flash drive, and inserted into the Mac.  I then copied the file from the flash drive to "Applications" on the Mac as instructed.  I try to open, but a window pops up telling me to copy the MBAM file into the "Applications" folder, but its already there.  So I read I needed to make a change to my security settings to allow apps to be installed from places other than the Apple app store.  So I did that, but still have the same problem.

 

Any ideas?
