Using free version of avast. It’d be nice if, instead of finding new ways of spamming us, a few bugs in the UI were actually fixed within 3 to 4 years. The columns in the Scan Results dialog can’t be resized, which, when the dialog opens as a small window, means the location of an infection is occluded unless you put your cursor over it and wait for the tooltip. That tooltip, on the other hand, might not be long enough to display the entire string.
Just in case i’m not making any textual sense, here’s a visual:
It does allow you to upload an attachment - when the Reply window is open - use the Attachments and other options. Clicking that expands the window to allow for attachments to be uploaded.
Hovering over the file location shows a tooltip box with the full location. But as for resizing the column, although the mouse cursor turns into the horizontal resizing cursor, it doesn’t work. And this is independent of the window size, which can be changed.
Unfortunately I can’t replicate that, as you can see from my images the horizontal resizing cursor is present and on dragging it expands my columns.
What operating system and avast version are you using ?
See my signature under posts for my system used in the checks.
On my images you will notice a slight difference to yours, in that I don’t see the column header separators. But hovering the mouse over that area produces the horizontal resizing cursor.
You could try an avast Repair and see if that makes a difference - Control Panel > Programs & Features > Avast Antivirus > Change. From the next windows select Repair, once complete reboot.
