Infection blocked when I visited https://us.etrade.com/home

Avast blocked infections this morning the first two times I attempted to log on to https://us.etrade.com/home. Since then I have had nothing blocked. When I looked in the log file I found something that appears to indicate an attempt to redirect. So I am now reluctant to trust logging on to ETrade even though Avast is no longer blocking anything. Below are the pertinent log file entries. Could anyone please tell me if I should be cocerned? Thanks in advance for any help.
