How To Remove Virus From Any Drive (USB PEN DRIVE)Using
Command Prompt (CMD) In Windows
For starters a virus is a self- replicating computer program
that infects your computer. These viruses are a menace and can spread across
multiple computers via USB/flash drives, external media and other means. As we
all know, there is a multitude of anti-virus software. To our dismay, not all
of them can do the trick. Sometimes, even your antivirus can fail to detect
some sort of viruses. Well, in such case, CMD prompt may be the solution to
help you solve the virus issues. Most of us grapple with viruses like
Autorun.inf, newfolder.exe, ravmon.exe, svchost.exe etc. They usually present
themselves as files and sometimes they can even be files hidden from you.
To remove a virus using CMD, we shall use a CMD known as
“attrib” command. Therefore first we have an obligation to know a few basics of
the attrib command.
R – represents the read only attribute of a file or folder.
Read only means the file can’t be written or executed.
H – H stands for the hidden attribute.
A – Similarly A stands for Archiving and this prepares a
file for archiving.
S – This attribute changes the selected files or folders in
a system file from a user file by assigning the “system” attribute of that
particular file.
Here we have the “attrib” syntax à
ATTRIB{+attribute/-attribute}{pathname}[/S[/D]}
And with the above command there are different parameters
and switches so lets see what they are.
+/- à to enact or to cancel the specified attribute.
D à include any process folder.
S à searching
through the entire path. Sub-folders inclusive.
Attribute à ( already explained above)
Pathnameà path where target folder is located.
This here is the proper syntax for the attribute command:
ATTRIB{+R/-R}{+A/-A}{+S/-S}{+H/-H}{+I/-I}{drive:}{path}{/S[/D][/L]}
After knowing all of the basics, now let’s give it a shot
and try to see how we can remove a virus from
USB, SD card etc. using CMD
prompt.
For example, let’s transfer an autorun.inf virus from my USB
to my D drive and delete the virus from the D drive.
Step 1. Open command prompt from search and run as
administrator.
Step 2. Type D and hit enter
Step 3. Type “attrib” and press enter. This command lists
out all files inside the current drive and you will clearly see autorun.inf
virus listed.
Step 4. At this stage to remove the virus using CMD, type
into command prompt “attrib –r –a –s –h . “ And press enter. This in turn will
remove the read only, archive, system and hidden file attribute from all the
files.
-r is for removing read only files
-a is for removing the archive file
-s is for removing system file
-h is for removing hidden file
. is for files with all different types of file extensions.
