My home page was www.comcast.net (my isp) and after my homepage loaded I would navigate away and go about my business on the internet. Every so often I would go up and hit the back button but nothing would happen, then click it again and still nothing. So I would bring down the drop down list of web pages and that web site (ad.yieldmanager.com) would be 2 pages back and I would have to choose the website just beyond that to get it to navigate back from where I came from. I currently pay for and use XoftSpySE v4.33 and Ad-Aware 2008 Plus Version 7.1.0.11, I also use Spybot - Search & Destroy 1.6.0 and your program Malwarebytes' Anti-Malware which are both free. I use these spyware programs regularly and they all find different things to remove each time I use them but niether ever come up with anything related to this yieldmanager spyware. I literally spent 5 hours straight last weekend trying to remove this from my computer, this being one attempt of several over the last few months all of which have gotten me nowhere. Now here is where it gets wierd. I started noticing if I did not let my comcast.net (my isp) homepage load completely before I navigated away, then the yieldmanager site quit appearing in my recent visited sites list and I could use my back button normally anytime I tried. Then as soon as I went to my comcast.net homepage and let it completely load ad.yieldmanager.com would be back almost immediately. Due to this I changed my homepage to another site and reran all my spyware programs and have avoided comcast's home page for a week now and have yet to see yieldmanager show back up. Can you explain this to me, why would my internet service provider put this into thier homepage? I don't understand why that would be, why would a huge corp. like comcast let something like this spread from thier homepage, not only did it mess with my back button and act as a tracking cookie I swear it slowed down my computer. Do I have a virus that is just attacking through that site or is it from comcast, I surely can't figure it out. Thanks for any advice you can give me Casey This post has been edited by Orange Blossom: Sep 18 2008, 11:42 PM Reason for edit: Deactivate link and move to more appropriate forum. ~ OB

Extract (unzip) the file to its own folder C:\hosts. (Click here for information on how to do this if not sure.) Open up the hosts folder and double-click on the mvps.bat file. The script will rename your present HOSTS file to HOSTS.MVP and copy the new HOSTS file to the correct location on your system. You can read more about what we are doing in Blocking Unwanted Parasites with a Hosts File. MVPS HOSTS File Install Instructions with screenshots if you need them. Then download and install SpywareBlaster. -------------------- "THE BAD GUYS DON'T NEED A SEARCH WARRANT. ARE YOU PROTECTED?"

New Member Group: Members Posts: 5 Joined: 13-September 08 Member No.: 238,505	Okay did that this morning and now throughout the day I am getting the same result just now it is several differnt sites instead of the usual ad.yieldmanager.com not it is pn1.adserver.yahoo and a couple of hours ago it was a differnt one and couple hours before that yet another different one than either of the two previously mentioned. Although I have not seen the ad.yieldmanager.com I now have seen 3 new sites pop up in my list of visited sites and when I press back button nothing happens. I even turned on ad-watch just the cookie setting turned on and it has detected nothing. I just don't know what else to do, I even went as far as running all my virus softwares in safe mode and still this happens.

Also completed atf cleaner and the other item you wanted me to install I guess I will just monitor it for a couple of days and if the problem returns I will let you know.

Bleepin' Janitor Group: Global Moderator Posts: 16,573 Joined: 9-July 05 From: Virginia, USA Member No.: 26,513	If there are no more problems or signs of infection, you should Create a New Restore Point *to prevent possible reinfection* from an old one. Some of the malware you picked up could have been saved in System Restore. Since this is a protected directory your tools cannot access to delete these files, they sometimes can reinfect your system if you accidentally use an old restore point. Setting a new restore point AFTER cleaning your system will help prevent this and enable your computer to "roll-back" to a clean working state. The easiest and safest way to do this is: Go to Start > Programs > Accessories > System Tools and click "System Restore". Choose the radio button marked "Create a Restore Point" on the first screen then click "Next". Give the R.P. a name, then click "Create". The new point will be stamped with the current date and time. Keep a log of this so you can find it easily should you need to use System Restore. Then use Disk Cleanup to remove all but the most recently created Restore Point. Go to Start > Run and type: Cleanmgr Click "Ok" Disk Cleanup will scan your files for several minutes, then open. Click the "More Options" Tab. Click the "Clean up*" button under System Restore. Click Ok. You will be prompted with "Are you sure you want to delete all but the most recent restore point?" Click Yes, then click Ok. Click Yes* again when prompted with "Are you sure you want to perform these actions?" Disk Cleanup will remove the files and close automatically. -------------------- "THE BAD GUYS DON'T NEED A SEARCH WARRANT. ARE YOU PROTECTED?"

Bleepin' Janitor Group: Global Moderator Posts: 16,573 Joined: 9-July 05 From: Virginia, USA Member No.: 26,513	There may be another piece of malware on your system that we have not found so further investigation is required. Before that can be done you will need you to create and post a hijackthis log. Please read the pinned topic titled "Preparation Guide For Use Before Posting A Hijackthis Log". If you cannot complete a step, then skip it and continue with the next. In Step 9 there are instructions for downloading the HijackThis Installer and creating a log. This is an automatic setup version which will install the program in the proper location. When you have done that, post your log in the HijackThis Logs and Malware Removal forum, NOT here, for assistance by the HJT Team Experts. A member of the Team will walk you through, step by step, on how to clean your computer. If you post your log back in this thread, the response from the HJT Team will be delayed because your post will have to be moved. This means it will fall in line behind any others posted that same day. Start a new topic, give it a relevant title and post your log along with a brief description of your problem, a summary of any anti-malware tools you have used and a summary of any steps that you have performed on your own. An expert will analyze your log and reply with instructions advising you what to fix. After doing this, we would appreciate if you post a link to your log back here so we know that your getting help from the HJT Team. Please be patient. It may take a while to get a response because the HJT Team members are very busy working logs posted before yours. They are volunteers who will help you out as soon as possible. Once you have made your post and are waiting, please DO NOT "bump" your post or make another reply until it has been responded to by a member of the HJT Team. Generally the staff checks the forum for postings that have 0 replies as this makes it easier for them to identify those who have not been helped. If you post another response there will be 1 reply. A team member, looking for a new log to work may assume another HJT Team member is already assisting you and not open the thread to respond. If after 5 days you still have received no response, then post a link to your HJT log in the thread titled "Haven't Had A Reply In Five Days?". -------------------- "THE BAD GUYS DON'T NEED A SEARCH WARRANT.
