Recently whenever I plug in a USB into my laptop, the file folders on the USB will start to be changed to shortcuts (I plugged in 2 different USBs and both experienced the same thing). In addition, randomly named shortcuts (i.e. 77420) will also appear in the USB. I could however, still access folders that I previously created and were changed to shortcuts.
The file folders on my laptop appear unaffected, they have not been changed to shortcuts nor have there been any random shortcuts appearing. I've run Malwarebytes to do scans on both my laptop and the USBs but nothing turned up.
As such, I'd like to enquire if:
1) Are the two USBs infected with any trojan/virus?
2) Is my laptop infected?
Edit: My laptop now keeps receiving "Windows Explorer has stopped working" messages, and have difficulties connecting to the internet. It also keeps switching to use a proxy instead. My windows firewall and Symantec Endpoint protection has also been disabled and I can't turn them on anymore.
Many thanks and much appreciation for your help!
