Computer was (possibly) infected with something. Symptoms were that it would not let me download and run any programs, particularly virus scans - and browsers (Firefox and IE) seemed to have their proxy settings changed which prevented opening websites. Finally, successfully downloaded Malwarebytes in safe mode, and ran in regular operating mode - deleted the 7 items that it found.

After I restarted, everything seems better. No problems with browsers. Java asked to update, which apparently had been blocked before. The only remaining symptom (??) is that Windows Update can not be run or turned on (automatic updates).

So - is this really a symptom of something? What should my next step be?

Thanks!

Can you post the log from Malwarebytes?

Here you go....

I also downloaded and ran Microsoft Security Essentials which found (and repaired?) some Java vulnerabilities and a backdoor.

SUPERAntiSpyware:

Please download and scan with SUPERAntiSpyware Free

  • Double-click SUPERAntiSypware.exe and use the default settings for installation.
  • An icon will be created on your desktop. Double-click that icon to launch the program.
  • If it will not start, go to Start > All Prgrams > SUPERAntiSpyware and click on Alternate Start.
  • If asked to update the program definitions, click "Yes". If not, update the definitions before scanning by selecting "Check for Updates". (If you encounter any problems while downloading the updates, manually download them from here. Double-click on the hyperlink for Download Installer and save SASDEFINITIONS.EXE to your desktop. Then double-click on SASDEFINITIONS.EXE to install the definitions.)
  • In the Main Menu, click the Preferences... button.
  • Click the "General and Startup" tab, and under Start-up Options, make sure "Start SUPERAntiSpyware when Windows starts" box is unchecked.
  • Click the "Scanning Control" tab, and under Scanner Options, make sure the following are unchecked (leave all others checked):
    • Ignore files larger then 4mb
    • Ignore non-executable files

    Now Perform the scan with SUPERAntiSpyware as follows:
    • Launch the program and back on the main screen, under "Scan for Harmful Software" click Scan your computer.
    • On the left, make sure you check C:\Fixed Drive.
    • On the right, under "Complete Scan", choose Perform Complete Scan and click "Next".
    • After the scan is complete, a Scan Summary box will appear with potentially harmful items that were detected. Click "OK".
    • Make sure everything has a checkmark next to it and click "Next".
    • A notification will appear that "Quarantine and Removal is Complete". Click "OK" and then click the "Finish" button to return to the main menu.
    • If asked if you want to reboot, click "Yes" and reboot normally.
    • To retrieve the removal information after reboot, launch SUPERAntispyware again.[list]
    • Click Preferences, then click the Statistics/Logs tab.
    • Under Scanner Logs, double-click SUPERAntiSpyware Scan Log.
    • If there are several logs, click the current dated log and press View log. A text file will open in your default text editor.
    • Please copy and paste the Scan Log results in your next reply.
  • Click Close to exit the program.

SAS Portable
If you have a problem downloading, installing or getting SAS to run, try downloading and using the SUPERAntiSpyware Portable Scanner instead. Save the randomly named file (i.e. SAS_1710895.COM) to a usb drive or CD and transfer to the infected computer. Then double-click on it to launch and scan. The file is randomly named to help keep malware from blocking the scanner.


Now GMER

GMER does not work in 64bit Mode!!!!!!

Please download GMER from one of the following locations and save it to your desktop:

  • Main Mirror
    This version will download a randomly named file (Recommended)
  • Zipped Mirror
    This version will download a zip file you will need to extract first. If you use this mirror, please extract the zip file to your desktop.
  • Disconnect from the Internet and close all running programs.
  • Temporarily disable any real-time active protection so your security programs will not conflict with gmer's driver.
  • Double-click on the randomly named GMER file (i.e. n7gmo46c.exe) and allow the gmer.sys driver to load if asked.
  • Note: If you downloaded the zipped version, extract the file to its own folder such as C:\gmer and then double-click on gmer.exe.

    Posted Image
  • GMER will open to the Rootkit/Malware tab and perform an automatic Full Scan when first run. (do not use the computer while the scan is in progress)
  • If you receive a WARNING!!! about rootkit activity and are asked to fully scan your system...click NO.
  • Now click the Scan button. If you see a rootkit warning window, click OK.
  • When the scan is finished, click the Save... button to save the scan results to your Desktop. Save the file as gmer.log.
  • Click the Copy button and paste the results into your next reply.
  • Exit GMER and be sure to re-enable your anti-virus, Firewall and any other security programs you had disabled.
-- If you encounter any problems, try running GMER in safe mode.
-- If GMER crashes or keeps resulting in a BSODs, uncheck Devices on the right side before scanning
.


All scans above should be performed in regular boot mode, and if that is not possible then I will post instructions in a follow up reply on how to get into Safe Mode to perform the scans. Also all scans should be COMPLETE and not quick unless specifically instructed to do so.
