Hello,
Today, I plugged a flash stick of a friend into my laptop, I accidentally clicked a shortcut folder while I was trying to delete it manually, right after that whenever I plug my flash stick two folders with my username and new folder and another one named 'bizo' are created automatically.
I'm using Avast Internet Security + Malwarebytes Anti-Malware.

Boot into safe mode and scan again with avast and mbam.

Does Avast have a feature that scans USB's automatically?

Also, plug the usb into another pc that has an anti-virus program that scans usb's automatically.

Hello,

I'm using Avast Internet Security + Malwarebytes Anti-Malware.

Have you tried using another memory stick / flash drive? This is just to verify if this is only an isolated problem.

You can try scanning using other security software as well and others may detect a malware.

Now, I don't have the virus in my flash stick, there's something wrong with Chrome, I run Adwcleaner and it always flags the following after the reboot :

now, there's nothing wrong with the flash stick. I cleaned it, but, there's a problem with Google Chrome, an extension is flagged as a malware or so.

Remove Chrome and install it again.
If its not within your extensions this should help.

Don't forget to remove data, you won't loose anything important if you have synchronisation.
