Can Avast! detect viruses that created their own exition with their own coding? Like 48TJG8GHI might be a virus code to shutdown pc and FN88BJVOinjg is their code for shutdown. I’m thinking that Avast! would just popup a “Suspishous” warning that it has different coding.
avast scans the content of a file to see if it is malicious or not. The name of a file doesn’t matter. Depending on your settings, avast can scan all files or only with certain extensions.
