So I'm usually careful, but got bit drunk and ended up downloading some naughty mp4 video files from direct download file upload site. And of course made copies and put them on external hard drive.

Come next day and hangover, cursed myself, deleted all videos from Mac and external hard drive.

Ran Malwarebytes, everything seems to be fine.

What else should I do (besides not getting drunk again...)?
The video files played all normally and were what I expected them to be.

1) Could I be infected? Will Malwarebytes find anything if there is anything to find?

2) Could my external drive and all my good normal files be infected? Could I infect other Mac systems with those files from external hard drive?

3) Could normally working mp4 video file contain something bad?

4) Could normally working mp4 video file leave something bad behind after I deleted it?

In short, how likely could my Mac and External Hard Drive be infected and would running Malwarebytes be enough to find everything if there is anything?

Not every 'naughty' video file has bad guys lurking inside (I'm told). hehe. If anything was there MWB would've caught it & dealt with it. I wouldn't worry. 


I've learned blood is not thicker than money.

So I'll just trust in Malwarebytes and not worry? No need to do anything else? :D

Well...not quite.  Malwarebytes is a good tool...but if it were capable of dealing with every form of malware...there would not be a need for any other malware tools...and there are plenty of them :).

 

Moved topic from Mac OS to AV/AM Software.

Hello! :)

 

Any advice what security apps to use in Mac? Some people say that better not install anything in Mac. I'm not sure what to do.

Just like traditional anti-virus and supplemental security software for Windows, there is no universal "one size fits all" solution that works for everyone.

FWIW, the first link is to a dead/404 page.

The second link just goes to a general page for technewsdaily.

Digital Trends renamed the article which broke the first link so it's been fixed. I just replaced the other broken link with one from MacWorld.
