yes have now worked out what to do; which is in case any others want to know, & without having to justify why you want to take control of your own computer to someone else who's business it isnt! open avast user interface, click on settings go to troubleshooting, click box disable avast! self defense module. go to services clock stop; then properties, then disable service & its stopped & disabled. Nice to be able to control whats on your own PC I say. Regards DW
