I found a strange folder in one of my drive's root today.
The folder name is
adf13d23ac52423b6504173ab679
the size of this folder is 6.12 mb
and the contents are two more directories.
1- amd64
2- i386
I upload two files to have a look on the contents. What I know is just that yesterday system was made some updates from Microsoft. And install drivers for my laptop but, I know that they makes a folder in the C:\ directory with the name SWSetup.
Thanks
