Avast very rarely misses a test (although it was absent from the last Linux comparative), and it generally does well all round. The product – the free edition, which usually appears in our desktop tests – always wins praise for its pleasant design and is simple to operate despite a wealth of configuration options for the wide range of components included (an impressive selection for a free solution). Installation is pretty fast and easy too, and there were no problems with stability even under heavy stress.
Scanning speeds were very good, overheads not bad, especially with the default settings which only cover some file types on-read. Our set of tasks took a little while to get through, but used little more memory or processor time than Windows Defender.
Detection was decent, if not as good as one might hope, and while there were no false alarms in our clean sets we did observe some misses in the WildList sets – apparently due to communication issues with the WildList operators. This was enough to deny Avast a VB100 award this time, despite an otherwise good showing.
