As mentioned, I got a new arrangement (Work) for a local movie. Possibly one of my biggest projects I ever received. Part of the music recordings needed to be done in a cave (Needed the natural Echo of drums and voice in a cave). For those in the music industry will know this is a good few days' camping to get the perfect sound.
Just before we left for location recording, I started noticing my PC taking extreme loading times on sound banks. Being new sound banks, I did not worry about it too much and just sat through the loading of it. At one point sat through watching the loading screen for just over an hour.
At location I realized I left my mobile internet modem at home. Not a huge problem since I do not need internet on location except for emails which I can get on my phone. This however was the tipping point of what was hiding on my PC. First day of recording I did not get to my PC but on the second day I needed to save a FLAC file I received to add to the project. Thinking of how long it takes to load the new sound banks, I started the PC up and went out for coffee. When I returned, logged in (Yes whole PC was at crawling pace) I received a message that I am not connected to the internet. I found it odd since I have nothing that needs to start up with the internet on my PC.
I did the ALT+SHIFT+ESC trick for task manager, and it opened 10 task manager screens (For some unknown reason) on the last one that opened I caught a glimpse of an unknown program that disappeared in the list. Closed all my task manager windows and went into start-up to see what changed and found nothing out of the ordinary in the startup list.
This is about where my "grey matter" kicked in and I remember the "SFC /scannow" command. Ran that and it returned that I had corrupted windows files that has been repaired. The big hunt started in task manager (that now just opened one windows as it should) and in there found a "start-up" grouping close to the bottom of the list. In there, there was an application just called APP and was linked to a file inside my temp folder which in return was linked to the internet.
Task manager startup tab showed the application, and I deleted it there.
Even though my PC is OK now (Speed is where it should be and able to work faster) I lost most of my documents and game save. Fortunate my important documents are backed up on an external drive, but my game saves are gone forever.
I am assuming it was some form of Malware or ransom ware but do yourself a favor and keep an eye on your start-up programs from within the task manager window. There might be something lurking in there wreaking havoc without you knowing. If I had my internet access with me at location, I would have just kept assuming it is the new sound banks.
PC is back to normal, with longest loading sound bank load time being around 5 minutes (As opposed to over an hour). How it got there I do not know, just glad it is gone and upset about having to restart most of my games......from scratch.
