 I infected this laptop by plugging in a usb flash drive. Since i hadnt had in plugged in to my other laptop in several months i didn't think it would be on there, soon as i plugged it in though the computer froze for a few minutes (1-2 min.) When it unfroze i wasn't able to open the windows explorer, i knew it was infected. I ran a few scans but again, it evades all scanner, even gmer. I ran aswmbr to check the boot record and this is what it found below. I was on semantic  (http://community.norton.com/t5/Tech-Outpost/Rootkit-Boot-SST-b-is-NOT-coming-off-PLEASE-help/td-p/588858) looking at blinking cursor during boot and the conversation there said that its a symptom of a modified TDL4 called boot.sst.b   

Hope that helps in helping me resolve both this and my other help topic.

Can't upload files either.

Hello and welcome to Bleeping Computer!

I am HelpBot: an automated program designed to help the Bleeping Computer Staff better assist you! This message contains very important information, so please read through all of it before doing anything.

We apologize for the delay in responding to your request for help. Here at Bleeping Computer we get overwhelmed at times, and we are trying our best to keep up.

No one is ignored here.

To help Bleeping Computer better assist you please perform the following steps:

    • Please do this even if you have previously posted logs for us.
    • If you were unable to produce the logs originally please try once more.

  • Notepad will open with the results.
  • Follow the instructions that pop up for posting the results.
  • Close the program window, and delete the program from your desktop.

Several things just happened. First Java, the auto verify page that popped up after i installed the new version (7.65)  was an unsecured webpage. I opened a new page and typed "verify my java" selected the first web result and it took me to a secured verify java webpage. I verified java but it said it couldnt find out of date versions to uninstall. I cleared java cache through java control panel before i updated. Went to the Microsoft uninstall panel and the new version of java doesnt show, doesnt show in ccleaner either. I havent done a reboot so that could be why but i didnt know java needed a reboot.

Second about DDS. The first download i accidently sent to downloads location so i downloaded twice and sent the second one to desktop. When i went to run it i saw the name is dds.com same name for the one in downloads location as well. So thats why i havent ran it yet because the name isn't right. typing dds.com in the search bar takes you to a dentist webpage instead of a search results. 

Waiting for more instructions on how to proceed.
