:o He y there I have been trying for a week to update both defs and sys but it freezes up I tried to uninstall but it giving a error message can you help
What OS/SP ?
What exact version of avast ?
What is the exact error message ?
Already tried a repair ?
How are you trying to uninstall ?
I have windows 7 home premium (Ligit) it says that after it starts to create a restore point it freezes. I forgot to mention I have tried repair it. I have tried to remove it from both avast control panel and from programs and features. It says the version is ffffff-ff so I have no idea
Try a repair from the control panel.
If that fails, get and use the uninstall tool and see if that will remove it.
If it does, install the latest version:

That should solve it.
In the rare case it doesn’t solve it, follow these instructions:

If you want a check for malware (or other things that can/need to be cleaned up),
