I am running windows 2000 on a 7yr old laptop. Since loading Avast AV I have been unable to log on as administrator. (I get log on box in which I can write the password then get “loading personal settings” which is as far as goes; I just then have a blue screen with the egg timer - it maybe something to do with a lack for resources- maybe something to do with virtual memory)
I can however log in as a subsidiary User.
As I think the problem is with resource hungry Avast I want to uninstall it. However I can not do this from the subsidiary User account.
1 Is there a way to uninstall from the subsidiary User account by someway overriding the restrictions?
2 And/or is there a way to get in to the administrator account?
Any help/suggestions much appreciated.
