This is only happening with Firefox and not Explorer. In my Yahoo Mail the webpage automaticlly redirects to another website: http://www.yim.com/?redir=frame&uid=www510acd907341f6.33698355
I can't read my mail and I can't figure out how to make the re-direct stop. I have already removed and reinstalled Firefox to no avail.
Please update to Firefox 18.0.1 Update Firefox to the latest version
Then Reset Firefox Refresh Firefox - reset add-ons and settings
Also scan for malware Troubleshoot Firefox issues caused by malware
Thanks for your response but unfortunately these steps do not solve the problem - other ideas?
You ran full malware scans with all the programs? That was fast
Do a malware check with some malware scanning programs on the Windows computer.
You need to scan with all programs because each program detects different malware.
Make sure that you update each program to get the latest version of their databases before doing a scan.
You can also do a check for a rootkit infection with TDSSKiller.
