This began last night. I went to check my yahoo e-mail account as usual, via my Firefox bookmark, and a window came up saying "We believe your account has been compromised" and asked me to create a new password. I was able to proceed to my Yahoo e-mail but was warned that I was at risk if I did so.
So far I have done an Avast boot-time scan of everything, no infection, Malwarebytes scan of everything, no infection, looked over my zonealarm logs, checked Belarc to see if security is up to date (it is), cleared the cache several times and logged into Yahoo via other means than the bookmark. The same window comes up each time.
Thinking about this, I opened an e-mail a few days ago from a friend who is traveling in Thailand. It was from her real account but it was clear her account has been infected when I opened the e-mail, which turned out to be spam. I am wondering if this somehow has now infected my Yahoo account. There was a delay of several days between opening her e-mail and then getting the Yahoo password window.
This has never happened to me before on any account so I want to make sure that the request from Yahoo is legitimate before I enter my password. Part of me wonders, if my account IS compromised, how do I know that this request will not lead to further problems. Googling this issue or reading within Yahoo help basically yields a variety of responses from different people, from "this is spam" to "this is legitimately from Yahoo."
I do not plan to change my password until I have a clearer understanding of the situation. For now I am checking my Yahoo e-mail despite the warning. I would hate to lose this account. I use it as a filing system for a number of business and personal e-mails. Also, this is the account I use for all business and most social contacts.
I would appreciate help in understanding what is going on and the best and safest way to proceed.
Thanks as always!
