Delete the virus autorun. inf in DOS

Today, a classmate has a virus in his computer, but there are many important things in the computer, such as virus-style Autorun. INF is a stubborn old virus. As long as the deletion is not clean, it will immediately copy and implant everything in the computer into such a file, which is usually in the root directory, when each drive disk is opened, the virus runs automatically, and is added to each drive disk. Then, the virus gradually spreads to each folder, in this way, we will slowly destroy your system!

In the case of a system, the virus cannot be deleted. Even if it is deleted, it will be generated immediately. If the system is reinstalled, the virus in other disks will be infected with the c disk, the worst way is to format everything and delete everything, but there are a lot of important things in its computer that you don't want to delete.

Later I thought about how to delete the stubborn viruses from Dos, but after running dos, the viruses were invisible and hidden, probably after processing, in dos, It is a hidden file. After checking the network, you can see that you have run attrib Autorun. INF-s-h-R, and then it will show that attrib shows or changes the attributes of the file. Therefore, after you enter the command, the file will appear and then run Delete Autorun. INF, you can delete it, but there is another problem, it will be very troublesome to delete it, because there are too many such files in the computer hard disk, if one goes to find and then delete it, it will be very troublesome!

After that, I thought of the batch processing files. It would be much easier to write a batch processing file, let the system search for it by itself, and then delete the files, finally, find "for % A in (c d e f g) do for/F" delims = "% B in ('dir/A/B/S % A:/Autorun. INF ') Do attrib "% B"-s-h-R & del "% B" ", which is a loop statement for your C, D, E, F, g. Find and delete the subfolders one by one. If there are more drive letters, add them to the back and finally delete them. This is really amazing! You don't have to worry about this virus in the future!
