Here I am giving you the simple trick to remove viruses from your machine by using DOS:

Step 1: Open Dos

Step 2: go to Parent directory (Like C:\, D:\) by command cd\

Step 3: Now Give the given command

attrib/s findstr SHR

Now this command will give you a list as shown in below figure......actually it gives you the list of file which are System, Hidden & Read Only.

One thing remember that there is no EXE or DLL files are hidden, system, read only in WINDOWS based OS. So that, in 90% cases the hidden system read only files with EXE or DLL extensions are viruses.

Once you have found out the virus files from your system.

Step 4: give command

attrib -s -h -r

del

Step 5: If there is any autorun.inf file then do the same for this file also.

Now repeat the process for all the drives
