Thank you for your reply but Avast has deleted the false positive files to the virus chest which means they have been deleted from various directories so either I restore after creating exception or just restore to gain access to the files. I'm fairly sure the files are false positives but thought it a good idea to see if any other user had the same files flagged.
Thanks for the link by the way I had forgotten Virus Total
By the way after posting Avast and Microsoft have both been scanning my PC and file locations while I watched via Windows Resource Monitor
An invaluable file check using the Windows Command Prompt is an easy way to find and repair any corrupted files - I use it often.
Click Search icon - bottom left - enter CMD - select Administrator - up comes the black Command Prompt -
enter - sfc /scannow and off it goes checking all your files and repairing any corrupted ones. It takes 20 minutes on my PC.
The Microsoft Malicious Software Removal Tool - MRT - will find any malicious files and delete them -
Press Winkey + X - select RUN - enter MRT.EXE - click OK - click YES on the popup panel - Click NEXT -select QUICK SCAN and you are away.
Takes just a few minutes.
