I've scanned my computer, now what?

Hello.
I recently installed the Avast 3.11RO on my iMac and now I need to take care of some viruses and warnings. I have no instructions nor directions provided with this download. Where do I go from here?

Hallo,
warnings have no implication of infection - it’s just about why the file wasn’t scanned thoroughly (inaccessible, unreachable, whatever).
they are in cyan. what’s important are the real viruses - in red. delete them using avast’s toolbox-button, or, open their location in finder (use “reveal in finder”), and manipulate them from there.

bnote: not all files could be manipulated. some are inner part of solid archives, and you must manipulate the file as whole (in such case, the parent-file is shown too, above the finding).

regards,
pc
