My son downloaded World of Warcraft from Riot Games and put the package on his desktop. He installed the game and left the downloaded package on the desktop. I noticed something was accessing his HDD at a very high rate. I opened resource monitor and traced it to the desktop install package of the game into a file called datacab2.
I hear some game suppliers like Origin will scan your comp for hacked/cracked versions of games but this is very unusual that it was not a file in the game after install causing this thrashing of the hdd. I deleted the install package and removed it from the recycle bin and it all went away.
other info: I booted the comp and had not opened the game and it was active thrashing the hdd from the install package on the desktop.
If anyone has any info , reason, or can find out, please reply. I posted here because it seems to me this extreme thrashing of the hdd would be destructive to a hdd over time and seems malicious in that way.
