Hi,

 

My chrome browser on the new windows 8 laptop opens yahoo search by default. I have tried changing this and a couple of anti virus and malware removal tools but of no help. Came across a few entries here like the one below where this has been resolved by your help.

 

https://forums.malwarebytes.org/index.php?s=5b2cb85031fe0d71fbd36cd90812424f&showtopic=143966

 

 

Could you please help resolve the issue on my laptop? Thanks!

Start with this: (make sure you have created a new system restore point)

Please download AdwCleaner from HERE or HERE to your desktop.

  • Double click on AdwCleaner.exe to run the tool.

    Vista/Windows 7/8 users right-click and select Run As Administrator

  • Click on the Scan button.
  • AdwCleaner will begin...be patient as the scan may take some time to complete.
  • When it's done you'll see: Pending: Please uncheck elements you don't want removed.
  • Now click on the Report button...a logfile (AdwCleaner[R0].txt) will open in Notepad for review.
  • Look over the log especially under Files/Folders for any program you want to save.
  • If there's a program you may want to save, just uncheck it from AdwCleaner.
  • If you're not sure, post the log for review. (all items found are adware/spyware/foistware)
  • If you're ready to clean it all up.....click the Clean button.
  • After rebooting, a logfile report (AdwCleaner[s0].txt) will open automatically.
  • Copy and paste the contents of that logfile in your next reply.
  • A copy of that logfile will also be saved in the C:\AdwCleaner folder.
  • Items that are deleted are moved to the Quarantine Folder: C:\AdwCleaner\Quarantine
  • To restore an item that has been deleted:
  • Go to Tools > Quarantine Manager > check what you want restored > now click on Restore.
Next..................

Please download Farbar Recovery Scan Tool (FRST) and save it to a folder.

(use correct version for your system.....Which system am I using?)

FRST <----for 32 bit systems

FRST64 <----for 64 bit systems

  • Double-click to run it. When the tool opens click Yes to disclaimer.
  • Press Scan button. (make sure the Addition box is checked)
  • It will make a log (FRST.txt) in the same directory the tool is run. Please copy and paste it to your reply.
  • The first time the tool is run, it makes also another log (Addition.txt). Please attach it to your reply.
If the logs are large, you can attach them:

That looks Good.......

A little clean up to do....

Please Uninstall ComboFix: (if you used it)

Press the Windows logo key + R to bring up the "run box"

Copy and paste next command in the field:

ComboFix /uninstall

Make sure there's a space between Combofix and /

cf2.jpg

Then hit enter. (it may look like CF is re-installing but it's not)

This will uninstall Combofix, delete its related folders and files, hide file extensions, hide the system/hidden files and clears System Restore cache and create new Restore point

(If that doesn't work.....you can simply rename ComboFix.exe to Uninstall.exe and double click it to complete the uninstall or download and run the uninstaller)

---------------------------------

Please download OTC to your desktop. (This will clean up most of the tools and logs)

http://oldtimer.geekstogo.com/OTC.exe

Double-click OTC to run it. (Vista and up users, please right click on OTC and select "Run as an Administrator")

Click on the CleanUp! button and follow the prompts.

(If you get a warning from your firewall or other security programs regarding OTC attempting to contact the Internet, please allow the connection.)

You will be asked to reboot the machine to finish the Cleanup process, choose Yes.

After the reboot all the tools we used should be gone.

Note: Some more recently created tools may not yet be removed by OTC. Feel free to manually delete any tools it leaves behind.

Any other programs or logs you can manually delete. (right click.....Delete)

IE: RogueKiller.exe, RKreport.txt, RK_Quarantine folder, C:\FRST folder, FRST-OlderVersion folder, MBAR folder, etc....AdwCleaner > just run the program and click uninstall.

Note:

If you used FRST and can't delete the quarantine folder:

Download the fixlist.txt to the same folder as FRST.exe.

Run FRST.exe and click Fix only once and wait

That will delete the quarantine folder created by FRST.

The rest you can manually delete.

-------------------------------

Any questions...please post back.
