I transferred some family videos from my Android phone using Mixplorer (I've used this method countless times) and played the files back yesterday using Potplayer indicating the files had transferred over but when I came back to my computer the files had disappeared! Stupidly, I cut and pasted, instead of copy and pasted.
I then made a video file the same way I did with the lost video files to check the filename format and used a search app called Everything to search for the files using their dated filenames, nothing.
I checked the recycle bin and I used Recuva to find the files straight away using a deep scan but they couldn't be found.
I then used WinfrGUI, Windows File Recovery and Testdisk but all with no luck.
I then started to think it's a virus however I have a major in computing, computer literate and never download or open suspicious files or emails. I have never had a virus my entire life, no suspicious activity on my computer such as processes that hog my CPU or network, no disappearing files, etc.
I unplugged my computer from my network, ran M$ defender in safe mode and Bitdefender but no suspicious files.
Anything else I need to do? I'm a bit concerned to mess with any other files on this drive if they have been compromised.
