USB files blocked turned to trz**.tmp

I have lots of files in my USB flash disk.

Inserted it on my office computer with avast antivirus.

The software blocked my files and turned them to trz**.tmp.

How can I restore them? They cant be seen in the vault or anywhere else.

Help!

hey and welcome to the forum.

what software chanced your file on the usb drive?

I have encountered this once,just rescan the stick with avast and it should get those files out or just try renaming the temp files to .exe.
