Recently i noticed that quite of number visitor came to my blog view my post ‘how to disable autorun.inf to prevent virus attack computer ‘ .I don’t know either they want to get the preventive action or need to find the solution that computer infected by autorun virus.Here i will conclude my solution or method to help all of you.(i use this solution help my friend to ‘kill’ these virus and worked).
step 1 – Click ‘Control Panel’ -> ‘System’,
step 2 – Select ‘system restore’,then put check for ‘turn off system store on all devices’.
2 – Clear IE temporary internet files.

step 2 – In internet temporary file,select ‘delete file’ -> check for ‘delete all offline content’.,then click ‘ok’.
3 – Disk clean up.

step 3 – After complete disk cleanup,put check to all file and click ‘ok’.
step 4 – Repeat step 2 to step 3 for other drive ( D,E,F…) to have disk cleanup.
Now all the temporary internet files clean up already.Normally autorun virus are caused by flash memory or other removable devices to transfer,save file from one computer to another computer,these autorun virus have three execute file,kavo.exe,autorun.inf and ntdelect.com .
These 3 files all are hidden files,they will disable or hidden your folder option ‘show hidden files and folder’ and make you can’t run in ‘show hidden files and folder’,then you can’t search for these 3 files in window and deleted it (very clever,isn’t ?).
