There is system when i insert my flash drive to copy an application from the PC,i finish copying the file.I insert the flash into my PC and discovered that there is virus in the flash, i scanned it and delete the infected files. After deleting the infected files, i checked the flash drive and discovered that all the folders in the flash has became .exe and it has been deleted from the flash. The system that i copied the application from, i scanned the system and the antivirus detect no virus on the system, i schedule the boot-time-scan still it does not found any virus. I think that there are some malwares,spywares in the window’s files. and there are some software that can detect clean malwares and spywares from the PC.
Try this:-
download them and install, after installing them use it to scan your computer, if found delete the infected files. but if the malwares is not remove, it means your usb hub is having the problem, try and scanning for virus. if it doesn’t the Best thing to do is to format your PC.
