Hmm, access denied? That’s strange… I thought it would be a ‘sharing violation’ error instead - but anyway, does the file exist? I mean, can you see it in the Explorer (or whatever file manager you use) after you dismiss that avast window? And can you delete it?

Have you set the resident scanner sensitivity to ‘High’? Is this an alert that is triggered when you’re opening the file, or rather saving it (or IE saving it to its cache) – I mean, at what stage does the alert virus happen?

Does the same behavior occur even if you try to run that eicar file?

Thanks
