Paranoid, thanks for the input. I think I made it clear my AVAST Free is doing it's job as far as the protection goes. I'm just trying to sort out the reason why these error files suddenly appeared with the installation of 8.0.143 and ONLY in Full Scan. There is no password barrier, all scans are default and these errors-files do not show up on the scanning logs for Quick and Boot-time Scans, nor when I run Malwarebytes and SAS. It was never a problem with AVAST 7. As for AVAST 8.0.142, I don't know because I only ran the Quick and Boot-time Scan and no error files were revealed. So it is a mystery I'm trying to solve. I may uninstall .143, install .142 & if the error files show up...I'll be able to pinpoint the 'glitch' is definitely Version 8 related. Like a hang nail, it won't kill ya but they can be a nuisance. If no other AVAST users are reporting the error file quirk, then it is obviously only a minor disagreement between my PC and AVAST 8. Regards.
