I have Vista and recently installed avast! 4.7 Home/Professional Edition. After a while, I uninstalled it and now find that I am not able to view any emails (in Internet Explorer 7) and cannot see my messages in Yahoo Messenger IM window/archives.
I am able to browse normally in Firefox and check emails also.
What should I do now to get back to my old state? Any and all help will be greatly appreciated.
