Okay so i'll post now but i guess that you won't respond. I start to ask myself if there is some good at posting such things or i'm just wasting my time.
I've turned all shields for 10 minutes off from the right-click of the tray, then opened the interface and clicked the "FiX ALL" button, it changed from a red "X" to the yellow sign and showed "dashboard.some_shields_off.action" and the FIX ALL button disappeared. The web shield was showing as off in the settings, so i turned it on and clicked OK. Now it is showing as ON in the settings and off in the main GUI. I tested it with EICAR and it is actually off, the file was blocked by the file shield after download, not during the download by the web shield. Now what i'm waiting for is for someone to come and say: "Open control panel and repair because the avast team doesn't care".
