Regarding a possible virus

[mikhailivankov]

Yesterday I downloaded a file that claimed it would install Dolby Atmos on my computer. I was skeptical at first since it was not an .appx file, but I scanned it using BitDerender and the results were initially safe so I proceed to open the file.

 

Nothing appeared, no UAC warning, no setup, and Atmos was definitely not installed. I tried opening it again, this time I was looking at the task manager and I've found that it is was running at least three instances of the command prompt. It was then that the antivirus blocked the file. I used MalwareBytes and it deleted a file on Loca/Temp called dup2patcher.dll. I restarted my PC since BitDefender locked my access to hidden files and when I booted again I tried to scan my PC using BitDefender.

 

But I thought something was wrong because everytime I tried to open BitDefender by double clicking it's icon on the windows tray, the other icons "flashed", like when my mouse is over them for a second before the antivirus opened. I found very odd that this only happened when I tried opening BitDefender, all the other programs that I tried to launch via the windows tray behaved normally so I'm thinking that maybe something is wrong with the antivirus itself. Here's a video of it happening, as I think my explanation is somewhat vague and hard to understand.

 

Furthermore once when I tried to restart my computer I the following process was preventing it from restarting: CoreSync::â€<musync::â€<WSystemâ€>ObserverImpI

 

I've searched it up and it seems that it linked to Adobe software, but given the circumstances and the fact that this never happened before I'm afraid that this is linked to all of this.

 

Today I tried to end all processes I could and leaving the task manager to check on my CPU usage. It stayed on 2%, it occasionally went to 3% but never more than that if I left my PC unused.  I'm wondering if the BitDefender thing is linked to a virus, and if so, if I should format my PC or try removing it some other way.

 

Any advice?

 

Thanks in advance.

Certainly some cause for concern, personally I would pull any important files, but on a file by file bases off the machine, and then properly format every drive and reinstall windows. Neither quick, nor fun but better safe than sorry.

I don't have any other Hard Drive to backup my files to. I could use a Linux bootable USB to format my faulty one, then format the other one and put the files back in it. Would that do the trick?

 

EDIT: Or format the SSD and use it instead of the faulty hard drive since it's awfully slow and I'm afraid it'll break it at any second.

Thanks! I thought so, but given the circumstances I couldn't help but worry.

I've formated my PC, zipped some important files, put them on my SSD, formated the other hard drives and then put the files back on their original Hard Drive.

 

The issue with the Bitdefender icon was solved, and I've scanned both hard drives with Malwarebytes and Bitdefender. I've also used rkill and ADW Cleaner and all of the scans came off as clear.

 

But today the issue with the Bitdefender icon started happening again. I haven't found anyone with the same issue as me, and this is making me worry about the antivirus being hijacked even after all I did.
