¡Hello!
I have the Avast 6.0.1 in XP. It's the free version. In the interface of the antivirus there are many things to set, and therefore many windows of the submenus.Clicking on the left part of the antivirus interface (or window), you can read "Scan computer". If you click on this, there are many scans the antivirus can perform (Quick scan, Full system scan, Removable media scan, Select folder to scan, and so on). At the same time, each of these scans have a link, which says "Settings". Clicking on this link a new window opens for each of the scans. Well, the problem I have is that for some scans: Full system scan, Removable media scan, Select folder to scan and so on, when the "Settings" window opens (which has on the left part several tabs: Scan, Sensitivity, Packers, Actions)some of these tabs(windows)are atenuated. Therefore, they don't allow me to choose the settings I want. For instance, for "Full system scan", in the Scan tab, the Scan parameters window opens, but I can't choose the settings I want for it seems the window is toned down.
