I running the trial version of Dr. Web and I cannot figure out how to use the scan tree panel. I click on the drives and they get a mark on them, but then I can't see how to start a scan, deselect files, etc. And I cannot figure out those five buttons on the left of the panel. The only way I managed to do a scan is by right-clicking, browsing to a single drive, and then clicking on scan. Also, does Dr. Web have a way to have it automatically check for updates.
