I just woke up to check for a response.  I will do it when I wake up. It looks like I have the same suff but more now.  I have turned off the computer until I got a response from you. I hope that ok. When IE comes up after boot the windos firewall comes.upand says some files cant be viewled do I want to give it permission to let it the othe option is cancel. I didnt know what to do so I just use "X" ?to close it. I have never seen it do this before. So I hope I am doing the right thing. I may have some important files to send out today. I doubt we will be online at the same time. So if there are other thing you want me to do or can do before you get a chance to read tje logs just let me know. I will try and download thri IE again and let you know. Sorry for all the questions but I may need to use my computer later.
Thank you for your help again. Maybe we will be on at the sometime. I will cross my fingers,
once again THANK YOU again

This sounds familiar. I know what the problem is, as I suspected before. Also This new malware block all malwareremoval tools from downloading and using ... this is still new for all of us.


Try to run TDSSKiller, ComboFix via CFScript and most importantly run latest zoek script. I need to see all logs. Run them from normal or safe mode but i need to see logs.
In any case, if you fail to run one tool, skip it and run other. Zoek and his JunctionPoints.txt log is temporaly very importantly to me to solve the problem.

Hi,

You have attached wrong ComboFix logs. Read again CF instructions.
I'm waiting JunctionPoints.txt log too.
