I have no idea a.t.m., but I am still missing some info, which may help us to find and solve the problem.
What EXACT version of avast? (there are mutliple versions of 4.7)
OS? You say 2kpro, sp4. So you have the client version installed? (just asking to make sure)
avast is looping me back to the login screen whenever I try to click on anything in hotmail live mail and I can only load the version for slow internet connections the other one won't load at all.
Please update me. I thought hotmail is webbased and only works with outlook (express) or if you have a 3rd party application.
And what do you mean with "the other one won't load at all"?
Sofar it seems like a hotmail problem to me. But at this point it is too early to come to a definate conclusion.
Please feed us with more (possible) relevant information.
EG: Disable one avast provider at a time to see if it is just one provider that is causing this or not.
