Why is yahoo asking for my password?

Why does Yahoo keep asking for my email password?

• This morning I have been trying to weed out and delete unimportant emails in my Yahoo email and Yahoo keeps locking me out about every 30 seconds and requires that I re-enter my password. I checked my settings and it was set to lock me out and require me to re-enter my password only once every 2 weeks. I signed out of my account and then signed back in, but it didn't help. I've had this email address for about 5 years and I've never had this problem before. I'm not doing anything differently. I don't want to abandon this email address and get a new one. Is this a problem with Yahoo that other people are experiencing or could it be a problem with my particular email address? Is there anything I can do to fix this? Thanks in advance for any helpful information.

• Answer:

  First I'd ask yahoo support whats going on.. if they have the answer then so be it. If not then I think you might have malware on your computer or your internet browser settings are messed up. Go to tools>Internet options>Advanced tab>Reset if that don't work try the below.. 2. http://onecare.live.com/site/en-us/default.htm <---- Free scan it removes anything harmful on your computer and puts it in quarantine or in other words stops the virus & malware. The scan is a very deep and detailed scan from Microsoft, which is very secure but may take a while. 3. Get http://www.malwarebytes.org/ <---- Free anti-malware which knocks out malware. If you have the boughten version then you will get, website blocking, automatic scans/updates when you want to, active protection, one lifetime low fee etc. Free version you have to do everything manually and you wont get some of the extra features. Once you've gotten Malwarebytes' Anti-malware then do a full scan. 4. I use Microsoft Security Essentials Anti-virus/Spyware & Malware. I never had a problem ever since I had all this with my computer. http://www.microsoft.com/security_essentials/ 5. Change your password on Yahoo as someone may know your password. Hope that helps you out.
