    Mysterious files and folders appearing - Are they Malware?


    Hi,

    I was looking for files on my Windows 7 desktop when I stumbled on a strange folder in my "Documents" folder. The contents looked like a dictionary had thrown up. There were 10 files and each had a random string of nouns. Attached is a screenshot. I found two similar folders in C:\ and C:\Users. My antivirus software (Avast) says that there is nothing wrong with the folders. Is this malware? If so, any idea which one and how I can fix it?

    I ran the first three and quarantined/deleted over 500 PUPs. However, I tried to delete the mysterious files using Eraser (https://eraser.heidi.ie/), but they just appear again. I just realized that these several of the mysterious folders have names similar to another folder, ie 2011 Absystem155 and 2011 Accounting. The folders are set to "Read-only" and "hidden". Could this be a ransomware program encrypting my system? Cyberrason RansomFree hasn't found anything.

    Also, I rebooted into safe mode to run those scans again. I checked and the files and folders were gone. However, when I rebooted, I watched the folders reappear. The folder names were the same, but the contents were different. Please Help.
