Run a full Avast scan. Right click on the A ball, load the On demand scanner. Then, click on each of the "drive" icons and set the scanner for a thorough scan with archives including all external and removal disks
yes, thats what i meant to say 
btw, if you did the thorough scan, tell me how long your pc needed for how many GB of datas (i’m just interested, because i posted a related thread some days/weeks ago)- cheers
