How can I report a bug where 4.8 Home Edition always freezes when it hits a certain program ?
You can start in the avast 4 Home/Pro forum, creating a new topic.
And give full details of the problem, what you were doing, the program effected and exactly what happens, errors/warnings displayed, anything in the windows event viewer, etc.
Other details, such as your OS, any other security software.
Have (or did) you another AV installed in this system, if so what was it and how did you get rid of it ?
Are you using the program and the resident freeze this program?
Or are you using the avast on-demand scanning and it was avast which froze?
