Hi,
I got an error today. I’m using version 7.0.1466. My OS is Windows 7 64bit with SP1.
AvastUI.exe Free The exception unknown software exception (0xc015000f) occurred in the application at location 0x77e44621.
Any help would be greatly appreciated. Thanks 
does it mean the program will not run?
have you tried a reboot?
tried avast repair?
The program seems to still be running. I haven’t tried a repair yet. I’ll reboot now and see it it happens again.
How do I repair avast?
Win7 - Control Panel, Programs & Features, uninstall a program, select ‘avast! Anti-Virus,’ click the Uninstall/Change and select Repair, click next and follow.
You may need to reboot after the repair.
isn’t there any mdmp file in avast log directory? https://support.avast.com/index.php?_m=knowledgebase&_a=viewarticle&kbarticleid=586#idt_05
