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 flash drive, check if these files are there or not
New Folder.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.
