I have had a problem with ad.yieldmanager.com redirecting me to a Dell search site when checking Yahoo! Mail. For a long time now I have been able to circumvent the problem by blocking ad.yieldmanager.com under the Privacy tab in Explorer Internet Options. I am not able to block it that way today, so I tried what was recommended here in your Malware removal section (i.e., I used the HiJackThis utility to "fix" the browser helper object - Browser Address Error Redirector). At this point, I am no longer being redirected to the Dell search page, but every Yahoo! Mail page change is interrupted by one or two popups requesting permission to open the trusted site "res://ieframe.dll." As you might imagine this is very annoying. Can anyone help me??
