Virus or something else?
Not sure if this is virus-related, but it sure has me baffled. I have two identical notebook computers with the same protection software and same browsers, IE and Firefox. Recently I noticed that with the computer that I'm on now (the other one is unaffected), using Firefox (works fine with IE), I can't access my Yahoo e-mail account. I can get to the home page and then sign in, but then I get this:
Not Found The requested URL /mc/welcome was not found on this server. Apache/2.2.9 (Debian) PHP/5.2.6-1+lenny9 with Suhosin-Patch Server at us.mc1302.mail.yahoo.com Port 80
Then when I go to a certain site, using Firefox (works fine with IE) that I've never had any problems with before, I get this:
Panda Cloud Antivirus Safe Search Protection

Full scans on my up-to-date Norton Antivirus 2011 (as well as Malwarebytes) software shows that everything is fine. Any input would be greatly appreciated.
