That seems to be okay. Please run MBAM and SAS

Please download Posted Image Malwarebytes Anti-Malware and save it to your desktop.
  • Make sure you are connected to the Internet.
  • Double-click on mbam-setup.exe to install the application or, if you are using Vista, right-click and select Run As Administrator on mbam-setup.exe to install the application.
  • When the installation begins, follow the prompts and do not make any changes to default settings.
  • When installation has finished, make sure you leave both of these checked:
    • Update Malwarebytes' Anti-Malware
    • Launch Malwarebytes' Anti-Malware
  • Then click Finish.
  • MBAM will automatically start and you will be asked to update the program before performing a scan. If an update is found, the program will automatically update itself. Press the OK button to close that box and continue.
    If MBAM won't update then download and update MBAM on a clean computer then save the rules.ref folder to a memory stick. This file is found here: 'C:\Documents and Settings\All Users\Application Data\Malwarebytes\Malwarebytes' Anti-Malware' then transfer it across to the infected computer.
  • On the Scanner tab:
    • Make sure the "Perform Full Scan" option is selected.
    • Then click on the Scan button.
  • If asked to select the drives to scan, leave all the drives selected and click on the Start Scan button.
  • The scan will begin and "Scan in progress" will show at the top. It may take some time to complete so please be patient.
  • When the scan is finished, a message box will say "The scan completed successfully. Click 'Show Results' to display all objects found".
  • Click OK to close the message box and continue with the removal process.
  • Back at the main Scanner screen, click on the Show Results button to see a list of any malware that was found.
  • Make sure that everything is checked, and click Remove Selected.
  • When removal is completed, a log report will open in Notepad.
  • The log is automatically saved and can be viewed by clicking the Logs tab in MBAM.
  • Copy and paste the contents of that report in your next reply and exit MBAM.
Note: If MBAM encounters a file that is difficult to remove, you may be asked to reboot your computer so it can proceed with the disinfection process. Regardless if prompted to restart the computer or not, please do so immediately. Failure to reboot normally (not into safe mode) will prevent MBAM from removing all the malware. MBAM may make changes to your registry as part of its disinfection routine. If you're using other security programs that detect registry changes, they may alert you after scanning with MBAM. Please permit the program to allow the changes.


And

Download Superantispyware
  • Load Superantispyware and click the check for updates button.
  • Once the update is finished click the scan your computer button.
  • Check Perform Complete Scan and then next.
  • Superantispyware will now scan your computer and when its finished it will list all the infections it has found.
  • Make sure that they all have a check next to them and press next.
  • Click finish and you will be taken back to the main interface.
  • Click Preferences and then click the statistics/logs tab. Click the dated log and press view log and a text file will appear.
  • Copy and paste the log onto the forum.

I'm not sure MBAM updated either but it removed quite a bit of detritus. Please run ESET's online scan to finish up

I'd like us to scan your machine with ESET OnlineScan
  • Hold down Control and click on the following link to open ESET OnlineScan in a new window.
    ESET OnlineScan
  • Click the Posted Image button.
  • For alternate browsers only: (Microsoft Internet Explorer users can skip these steps)
    • Click on Posted Image to download the ESET Smart Installer. Save it to your desktop.
    • Double click on the Posted Image icon on your desktop.
  • Check Posted Image
  • Click the Posted Image button.
  • Accept any security warnings from your browser.
  • Under scan settings, check Posted Image and check Remove found threats
  • Click Advanced settings and select the following:
    • Scan potentially unwanted applications
    • Scan for potentially unsafe applications
    • Enable Anti-Stealth technology
  • ESET will then download updates for itself, install itself, and begin scanning your computer. Please be patient as this can take some time.
  • Copy and paste the resulting log in your next reply
If no log is generated that means nothing was found. Please let me know if this happens.

If you think a log should have been generated then go to C:\Program Files\ESET\ESET Online Scanner\log.txt to find it.

i can't get the computer online since about november 14, however, when i ran windows defender offline it asked to connect with the internet. so i plugged in the either cable and the computer talked with microsoft. that was about 11-20. we have aol, chrome, safari and explorer. when trying to run any of those i usually get a not installed service message. sounds like and can't complete your next step yet

Please run FSS, let's see if we can see why you're offline

Please download Farbar Service Scanner (FSS) and run it on the computer with the issue.
  • Make sure the following options are checked:
    • Internet Services
    • Windows Firewall
    • System Restore
    • Security Center
    • Windows Update
  • Press "Scan".
  • It will create a log (FSS.txt) in the same directory the tool is run.
  • Please copy and paste the log to your reply.
