Your welcome.
Something to remember when the brown stuff hits the fan, if you use other tools in the hunt for more infected files, etc. if you find any that weren't detected by avast, before quarantining or dealing with them send a sample to avast.
Open the avast Chest, User Files section (this is where you can put suspect files), File, Add, from the pop-up window navigate to the location of the infected file and select it. The original file remains where it was so now you can deal with it with the other tool.
Now from the chest right click on the file you added and select email to Alwil software.
There are tons of scum/scam-ware tricks like these, so don't lose any sleep over it just be aware of this style of trick, give someone a headache and sell them an aspirin (tell them they have a problem and here is the solution).
