Windows 7 virus

[toonbon]

My WINDOWS 7 has picked up a virus that  replaces words in Word documents and in pages loaded by Chrome with links to ads.  The system is also making frequent request for pages that then get flagged by Malwarebytes when they come in.  I'm currently running Malwarebytes Premium 3.2.

Thank you for any help.

Hello Kevin,

Thanks for jumping in.  I already have Malwarebytes Premium running so I included the threat scan from it.

Thanks for the results from VT, continue...

Download attached fixlist.txt file (end of reply) and save it to the Desktop, or the folder you saved FRST into. "Do not open that file when running FRST fix"
NOTE. It's important that both FRST and fixlist.txt are in the same location or the fix will not work.

Open FRST and press the Fix button just once and wait.
The tool will make a log on the Desktop (Fixlog.txt) or the folder it was ran from. Please post it to your reply.

Next,

Download AdwCleaner by Malwarebytes onto your Desktop. Or from this Mirror   Right-click on AdwCleaner.exe and select Run as Administrator (for Windows Vista, 7, 8, 8.1 and 10 users) Accept the EULA (I accept), then click on Scan Let the scan complete. Once it's done, make sure that every item listed in the different tabs is checked and click on the Clean button. This will kill all the active processes Once the cleaning process is complete, AdwCleaner will ask to restart your computer, do it After the restart, a log will open when logging in. Please copy/paste the content of that log in your next reply Next, Download Sophos Free Virus Removal Tool and save it to your desktop. If your security alerts to this scan either accept the alert or turn off your security to allow Sophos to run and complete..... Please Do Not use your PC whilst the scan is in progress.... This scan is very thorough so may take several hours...   Double click the icon and select Run Click Next Select I accept the terms in this license agreement, then click Next twice Click Install Click Finish to launch the program Once the virus database has been updated click Start Scanning If any threats are found click Details, then View log file... (bottom left hand corner) Copy and paste the results in your reply Close the Notepad document, close the Threat Details screen, then click Start cleanup Click Exit to close the program If no threats were found please confirm that result.... The Virus Removal Tool scans the following areas of your computer: Memory, including system memory on 32-bit (x86) versions of Windows The Windows registry All local hard drives, fixed and removable Mapped network drives are not scanned. Note: If threats are found in the computer memory, the scan stops. This is because further scanning could enable the threat to spread. You will be asked to click Start Cleanup to remove the threats before continuing the scan. Saved logs are found here: C:\ProgramData\Sophos\Sophos Virus Removal Tool\Logs Let me see those logs, also tell me if there are any remaining issues or concerns... Thank you, Kevin....

Kevin,

Here are the logs.  Sophus took about 8 hours to get through my 2TB of disk files. After a pass it would report 1 or 2 problems, I'd clean them, restart the program, wait another 8  hours. . . . After three times it still reported one problem and I cleaned it.  I checked my system then and it seems clean, so it looks like we caught what was causing what I was seeing. I need to use my computer, so I'll continue running Sophus each night until it gets all the way through without a problem.

What do you think?

Steve

Yes.

That is good news, when we clean up I normally post for Sophos to be removed, if you want to keep it for further scans just ignore that part...

Uninstall Sophos AV http://www.askvg.com/how-to-completely-uninstall-remove-a-software-program-in-windows-without-using-3rd-party-software/ Also delete this folder if still present: C:\ProgramData\Sophos Next, Download "Delfix by Xplode" and save it to your desktop. Or use the following if first link is down: "Delfix link mirror" If your security program alerts to Delfix either, accept the alert or turn your security off. Double Click to start the program. If you are using Vista or higher, please right-click and choose run as administrator Make Sure the following items are checked:   Remove disinfection tools <----- this will remove tools we may have used. Purge System Restore <--- this will remove all previous and possibly exploited restore points, a new point relative to system status at present will be created. Reset system settings <--- this will reset any system settings back to default that were changed either by us during cleansing or malware/infection Now click on "Run" and wait patiently until the tool has completed. The tool will create a log when it has completed. We don't need you to post this. Any remnant files/logs from tools we have used can be deleted… Next, Read the following links to fully understand PC Security and Best Practices, you may find them useful.... Answers to Common Security Questions and best Practices Do I need a Registry Cleaner? Take care and surf safe Kevin...
