I think your Avast Anti Virus software has been expired or you have not updated it because of which it not able to remove the viruses which is detected by itself. You must keep on updating the security software which you are using to secure your windows system as it would be getting all the updates about the latest viruses. Or it might happen that the copy of software which you are using would be a pirated one.

Actually Troj/QFas-B is an AutoCAD which has been found malicious on windows computer systems. This malicious file deletes all the AutoCAD files on an execution. It also attempts to backup those files with an extension of BAK. And you would be getting messages saying "BE recoverd!" or "MUST re_cover!"

If you are not able to remove any viruses from your computer then you can try to remove the same from the Safe Mode of the windows operating system. You have to restart your computer and then keep on pressing the F8 key which will open Booting Options for Windows 7. Here you would be having Safe Mode with or without Networking so click on whatever you want. Now you may try to remove viruses from your system.
