I am using MS Vista and each time I tried to go to my yahoo account I get a warning that pops up and says there is a malware threat. I chose to close it and it aborts me out of the web browser. I use mozilla - but I can go back to the site and pull up any other site like ebay msn etc. just when I go to yahoo. I tried to go to IE and it didn't like that at all. I found i have a trojan and I ran lavasoft ad-aware and it says it cleaned it but I still can't get to site. Now I can log in my laptop under my wife's account and go to my yahoo account with no problems. What can I do to correct this problem?

Hi, I suspect this issue is resulted by the following factors: 1.Advertisement. 2.Mozilla security extension warning. 3.Security software warning. 4.Virus. Before moving on, please scan your computer for virus. Then, please confirm whether the malware threat is a security warning or an advertisement. Please disable all your security software/Mozilla extensions temporarily, then try to visit yahoo. If it persists, it may be an advertisement. As you are using Mozilla, I suggest you install a content-filtering extension named Adblock Plus. It can help you block this advertisement. For your convenience: Adblock Plus 0.7.5.5 https://addons.mozilla.org/en-US/firefox/addon/1865 Writing Adblock Plus filters http://adblockplus.org/en/filters Important Note: This response contains a reference to a third party World Wide Web site.
