Most of the antivirus softwares cannot delete some viruses like Folder.exe, instead some anti viruses move them to quarantine but cannot delete them permanaently. Here is a trick to delete that kind of viruses permanently.
- After plugging in removable device or USB to your computer, a dialog box (Autorun) appears asking you to select the type of action needed to be performed. Click on “cancel”.
- Open “Run” from the start menu and type “cmd”. A command prompt will appear, then in the command prompt, type the letter of the drive which represents the removable device connected to your computer and press enter (Suppose that your flash drive is Removable Disk (G:) then type letter ‘G’ in the command prompt and press enter).
- Then Type “dir/w/a” and press enter. On pressing enter, a list of files belonging to your flash drive may appear. Check if files with the names Ravmon.exe, Heap41a, Autorun.inf, New Folder.exe, Svchost.exe or any other suspicious files are listed or not. Any matches with the above files indicate that your flash drive is infected.
- Now, in the command prompt type “attrib –r –a –s -h *.*” and press enter. On doing this will delete all the System, hidden, Archive and Read only file attributes from all the files.
- On performing the above only half of the work is done. To delete the infected files fully use a command “del filename.exe” (Suppose that 111.exe is the infected file then to delete it simply use a command ‘del 111.exe’).
- After performing that deletion operation your flash drive is completely safe and is free from viruses. *An important thing to note is turn off or disable the Auto-run feature of USB drives to prevent viruses from entering your computer even before scanning it using antivirus softwares.
