Yahoo mail spam issue?

Yahoo mail is often redirecting me to spam adverts. Advice?

• Hi... I've just posted this question in the "internet security" category but I am re-posting it here in the "Yahoo Mail Spam" category because maybe this category will get more/better answers. Thanks, and sorry if you are reading this twice. Just recently when I click on a link (sent mail, in-box, and actual messages etc.) in Yahoo Mail, I am redirected to a spam advert page for gambling. Here is the spam page http://pbid.pro-market.net/engine?site=119121+page=+space=9717+size=180x150+linktarget=%27_blank%27+rnd=1244539606 Sometimes this is so bad I can hardly use Yahoo because I'm battling to go back to Yahoo away from the gambling page while it keeps trying to go to the gambling spam page, and then sometimes it simply stops and Yahoo functions OK. I have contacted Yahoo about this (I only just sent the mail) and I have also scanned my whole computer for viruses, adware, spyware, and the scan result was clean. I am using AVG and AVG are looking into the issue. While I wait for Yahoo and AVG to reply I was wondering if anyone else has experienced these problems or if you have any advice or know what is going on? I've googled "pro-market.net" and its seems "pro-market.net" is related to spyware but I also realize companies like Yahoo do business with advert tracking companies such as "pro-market.net" and "doubleclick" who dump their tracking cookies on our computers. When pages load for Yahoo-Mail pages I also notice stuff loading for ad.yieldmanager.com which is a tracking cookie evil, I think. I am currently blocking all third party cookies but this is not helping. Thanks for advice and feedback

• Answer:

  A Google search tells me that pro-market.net is a malicious cookie that seems to be hard to get rid of. I found a site that offers a program to get rid of it, but I have no way of knowing whether it is genuinely helpful or something worse. Although it doesn't solve the immediate problem of cleaning out the malicious program, here is whois data from http://whois.domaintools.com/pro-market.net Registrant: AlmondNet, Inc. 134 Spring Street, Suite 302 New York, NY 10012 US Domain Name: PRO-MARKET.NET Administrative Contact, Technical Contact: Shkedi, Roy [email protected] AlmondNet, Inc 134 Spring Street Suite 302 New York, NY 10012 US 646-217-0930 fax: 646-349-2778 Record expires on 07-Nov-2009.
