Which of the two options that I mentioned did you try that the boot time scan is greyed out (option not available). Was it from the ‘start avast anti-virus’, Menu, ‘Schedule Boot Time Scan’ or in RajZor avast External Control Tool?
Please answer questions, it is the only way we can offer a suggestion - Help us to Help you.
You haven’t said what OS you use? I beleive the boot time scan may only be available to XP users (confirmation required here, RajZor does ECT, check OS for active menu choices). If that is the case then the option being shaded as you say would be valid.
Did you disable system restore as we have suggested? We need feedback to confirm what we suggest you tried, did it work, etc. if not were there any errors dd the virus come back, where was it this time, etc., etc. We need you input to help you otherwise we are wasting our time.
