Hello! my Avira just detected an infection with PHP/WebShell.A.1. It resides in
C:\Users\Default.Default-PC\AppData\Local\Google\Chrome\User Data\Default\Cache\ and it's called "f_004140".
I don't run any web-server on my computer whatsoever so I have no idea how I got it in here.
Anyways, here's the "source" of the file.

^ The link to the file itself.
(Scroll down to Raw Paste data). The extension is .file.
I used to run WAMP on my computer but I uninstalled it some time ago.
Any ideas on how to proceed for disinfection from now on? Cheers.
