There are some common virus that can spread
and infect your computer through USB drives.
These viruses include ‘Ravmon‘, ‘New
Folder.exe‘, ‘Orkut is banned‘ and some other
common viruses. Most antivirus either do not
detect these viruses or do not remove them (just quarantine them).
Steps —-
- When you connect USB with your computer,
you will get a window asking you what to do.
Choose ‘Cancel‘ here.
- Open command prompt by typing ‘cmd‘ in Run box (from Start > Run). In the command
prompt, write ‘drive letter:‘ and press Enter (let us say your USB is E so you will write E . – Now type ‘dir /w/a‘ and press Enter.
- This will display a list of files in your flaash
drive, check if these files are there or not
Autorun.inf
Ravmon.exe
New Folder.exe svchost.exe
Heap41a Or any other exe file which may be
suspicious.
- If any of the above file is there, that means
USB is infected by viruses.
- Type ‘attrib -r -a -s -h *.*‘ in command prompt and press Enter. This will remove the Read Only,
Archive, System and hidden file attribute from
all the files.
- Now just delete the files using the command
‘del filename‘ (for example, to delete a file with
name abc.exe I will use ‘del abc.exe‘). – Your USB now does not have any suspicious
file in it. To be on safe side you can now check
it with any antivirus to see if it has any such
file.
——-The end——
Note—- Disable the Auto-play feature of USB drives so that there are almost no chance of
virus spread. Tweak UI can do it for you ,
download Tweak UI software and install it. Run
the program and disable the Auto-run feature of
USB drives.
