I have a computer with windows 7 installed.
2 weeks ago I found out that I cannot find open many word,powerpoint ,txt pdf and picture files.
Some files are still readable.There was no ransomware message.
I might have stopped the process unknowingly. I remember killing a unknown process around that date.
All files were changed on the 29/6/2017 & 30/6/2017.
No I have a bunch of files that I cannot read.
I have loaded a few examples to ID Ransomware site but I got a result "Unknown ".
I have tested the HDD with CHKDSK with no problems.
Any Idea who to fix my files and identify the source of the problem ?
Could the reason be not a malware but something else ?
