A routine full scan with Avast! last night left an error message saying c:\program files\avast software\avast\defs\12120701\algo.dll Error: The system cannot find the path specified (3) - all this repeated several times for other .dlls (screenshot attached). The path certainly does not exist. The questions are, why has this message appeared, is it significant and do I need to do anything about it.
Regards,
Bob
