I found the following problem. I have malware currently not detected by avast!. This malware was located on USB Flash dirve K: I send this malware to the chest for subsequent sending to virlab via AvastUI → chest ->Add… etc. Everything is fine, file is currently in chest, but this USB Flash can not be ejected because of AvastUI.exe is locked the path K:\RECYCLED which was used during file chest moving. This path K:\RECYCLED is default now and is shown during next Add… command.
Yes, I can use ForceEject but is it correct behaviour?
If you boot, the lock will disappear, won’t it?
Yes, of course. But reboot is too radical mean. Simpler one is to put into chest some other file from any other directory. In this case old path (from USB) would be unlocked. New locked path would be the path of the latest item which was sent into chest during current session.
