Question: Virus/Ransomeware while using Logic

I am having some serious issues with my Imac (I think)


The first time I noticed some peculiarities is yesterday when suddenly MS Word would not start. It kept saying it had a serious error, and would start, but then it would immediately prevent me from going any further, and shut itself down. I didn't do anything about it, figuring I would deal with it later.


But I did run a thorough virus scan using Avast and it said I had 10 infections. I chose to delete them. (this in of itself was unnerving).


Later that evening I was recording a session using Logic Pro. Suddenly, a message came up saying that my computer may be being attacked by ransomeware. It then presented the Logic splash screen, but with two buttons. One said : Recover files? the other said Delete Them? I think, but I am not sure, that it specified that there 10 files in question.


Because I was recording an important session, and because I panicked, I foolishly clicked on Recover Files. Having realized that that choice was probably not a good thing, I immediately turned off my Mac.


Luckily, I use Acronis True Image and I make it a point to back up my entire Imac every week. I was thus able to recover my image. I chose an image from a couple of days ago (prior to my having the problem with Word).


The image worked and my computer was back up. I again re-ran a thorough scan and it again tells me that I have 10 infections (the scan is still running as I type but it is 97% done, having run overnight).


I notice that my computer is sluggish...often times presenting the little spinning circle rather than firing up apps...but not always. I also notice that Word still does not work, even though it did a week ago.


At this point, i have no idea what to do. Is my Imac infected with something serious?


I am using the free version of Avast. I was going to upgrade to the paid version once I got this infection thing happening, but I noticed they want a monthly payment, which I do not like the idea of.


I don't mind buying a virus package if it is a yearly renewal option, but I have no idea what is best to buy, or if this is somethign I need to do next.


I guess my main question is, what do I do next aside from waiting for the virus scan to finish and again delete the infections it found.


Should I restore my image from an Acronis recovery file that is older (perhaps a week back when I was not having problems?). Should I buy a virus scanner?


Thank-you for your time and expertise!


P.S. I am using High Sierra with 16 GB of memory. My Imac is a late 2009


I did not mean to cross post this, but it initially would not let me post to this forum, so i posted to the Logic forum first.

macOS High Sierra (10.13)

Uninstall Avast as per the developer's instructions. No Anti-Virus software or so-called “cleaning” apps are needed or recommended for Mac OS. They can conflict with Mac's own built-in security. At best they will slow your Mac by using unnecessary resources and at worst will bork your entire system. Avast is one of the worst and is known for flagging false positives.

Download and run Malwarebytes. Malwarebytes was developed by one of our own colleagues here in ASC and is about the most proven anti-malware software for Mac.

You may have a hidden recovery partition on your hard drive.


Press and hold the Option (⌥) key immediately upon hearing the startup chime and release the key after Startup Manager appears. Startup Manager will scan connected drives and will present drive icons of any volumes it finds, as shown below.


See if it shows up.

I agree with Pancenter, don't rush into things. I posted instructions for a factory reset because that's what you asked. But I don't recommend it at this point. Have you uninstalled Avast and used Malwarebytes yet and what did it report? And yes do a full backup of the disk either with Time Machine or a cloner software like SuperDuper! or CarbonCopy Cloner.

Hi Folks.


I am going to start from scratch for a number of reasons


1. I have copied all my critical music files onto another drive.

2. This Mac was suppossed to be meant for emails and browsing. But then I really liked Logic pro, so i decided to use this as my recording computer. So, I really want to clear all the crap off it that had accumulated .

That will enable me to use this only as a studio computer.


Thank-you for all the sound advice. It is now reinstalling High Sieraa.


I also have ncremental images of the previous content on a USB drive. So, if somethignnurgently is needed, I can resort to that.


I'll update this thread as I am sure I'll need help. Here are my plans:


1. Install the OS

2. Install maleware bytes (shoud, I install the free version?)

3. Install Acronis True Image for future image creation

4. Install my sound card stuff (Steinberg UR44)

5. Install Logic Pro X

6. Install plugs ins for Logic

Install nothing else !!! 😉


P.S. Is there any way to check whether the hard drive is healthy before I do steps 2-6?


Thanks again to each of you!!!!! I really do appreciate the help. This has been a frightful experience.

I don't know if this is normal. It says Installing on IMAC- 45 min remainng. Then it gets to the end of the 45 min and restarts the process again.

I don't know how this happened but my Imac refuses to do a [roper recovery through Actonis and the back ups I stored, or though its own internal reinstall.


This is so devestating.

I just wanted to thank-you all for the sound advice. In the end, I ended up recovering by using a friends time machine backup. They have the same Imac as me. So far. so good. I lost all my data files but I always keep the important ones on a network drive anyway.


I also ended managing to copy a few music files that were important to me.


Thanks again!
