I have been working to remedy this issue of Yahoo hijackng the homepage and the search engine on this laptop for hours with no resolve. I am retired, and working on computers is my hobby. I help several friends with their computer problems. I have exhausted every attemp at fixing this and it just keeps coming back. This nasty thing has infected my friends laptop, as well as his desktop. This will be a learning experience for me and I will gladly compensate whomever chooses to accept the challenge of helping me rid these systems of this malware.

  • 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.

  • Items that are deleted are moved to the Quarantine Folder: C:\AdwCleaner\Quarantine

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

  • Press Scan button.
  • It will make a log (FRST.txt) in the same directory the tool is run. Please copy and paste it to your reply.

You most likely got this infection from this program:
(IObit) C:\Program Files\IObit\Advanced SystemCare 7


Download the attached fixlist.txt to the same folder as FRST.
Run FRST.exe and click Fix only once and wait
The tool will create a log (Fixlog.txt) in the folder, please post it to your reply.

Then......reboot and let me know how it is, MrC

Good afternoon MrC. Thank you for your continued support. I do appreciate your time and effort.


To reiterate, this is a close friend's laptop which I maintain for him as well as his desktop.

Actually, this hijacker did not began with the install of IObit ASC. I have used ASC to tune up

the computers I have worked on for over a year. This laptop has had it installed and been in use

for probably close to a year also. I use ASC on my own machines too. I am beginning to think maybe

ASC is not the utillity I shoud be using for this purpose. I did some research and found too that using

any of the registry cleaners, which would include ASC', is not a good thing to be doing....ouch.


This laptop, and also his desktop, became infected with this hijacker about 1-2 weeks ago. I did not

realize he actually had malware doing this. I thought that he was just able to set his homepage

correctly in IE and FF. I went to his house this week to do some tuning for him and that's when I

discovered that they both were infected.


Because IObit shovels freeware to it's customers, I think the infection may have come from an

install of IObit Malware Fighter, or Driver Booster, both of which were on his computers. I did not

install them so I am assuming he must have clicked on a button he should not have, and here

we are....


I ran the FRST.exe program again. Here are the log files:

When you install ASC you get a bunch of other crap installed weather you want it or not and also it hijacks with spigot.
It's not a recommended program to have on the system, I would never ask you to install anything from IObit.

ASC has a Browser Protection feature under Tools somewhere that prevents you from changing any search or home pages.
If we don't disable that you won't be able to reset them.

So try to find and disable that or completely uninstall IObit and all the crap it comes with:

Advanced SystemCare 7 (HKLM\...\Advanced SystemCare 7_is1) (Version: 7.1.0 - IObit)
Driver Booster (HKLM\...\Driver Booster_is1) (Version: 1.2 - IObit)
IObit Uninstaller (HKLM\...\IObitUninstall) (Version: - IObit)
Smart Defrag 3 (HKLM\...\Smart Defrag 3_is1) (Version: 3.0 - IObit)


Let me know what you would like to do, MrC

I think I got it all in the attached fixlist.txt, I notice this VIPRE Search Guard Toolbar, please disable it so it doesn't interfere with the fix:


Toolbar: HKLM - VIPRE Search Guard Toolbar - {A924C17A-5E94-4E02-BED5-49720BA6F7FA} - C:\Program Files\VIPRE\VSGN.dll ()
Toolbar: HKCU - VIPRE Search Guard Toolbar - {A924C17A-5E94-4E02-BED5-49720BA6F7FA} - C:\Program Files\VIPRE\VSGN.dll ()


Download the attached fixlist.txt to the same folder as FRST.
Run FRST.exe and click Fix only once and wait
The tool will create a log (Fixlog.txt) in the folder, please post it to your reply.

Then......reboot if necessary and you should be able to set home and search pages now.
You can also just reset the browsers as before.

Let me know.....MrC

Hurray!!! MrC yor ARE the man! FF and IE8 are both working perfectly now.


Because I am very much interested in how this was accomplished, I would like to know how you use the log files from these programs to create the "fixlist.txt" file used to remedy the problem. Remember, I work on these beasts too? I still have the desktop with the very same hijacking issue to repair yet. Could I possibly repair the desktop myself, or would I need to get back to you for help doing it?


I have no clue how much time was involved for you to help me solve this problem on the laptop. I definately want to make a donation to you :)


I know there will be some cleanup left to do on this so I will await your reply.

Lets check your computers security before you go and we have a little cleanup to do also:

  • Save it to your Desktop.
  • Double click SecurityCheck.exe and follow the onscreen instructions inside of the black box.
  • If you get Unsupported operating system. Aborting now, just reboot and try again.
  • A Notepad document should open automatically called checkup.txt.
  • Please Post the contents of that document.
  • Do Not Attach It!!!

The securiy program ran but an error appeared so I tired to reboot and run it a second time...same little error box came up

but then the program continued. Here is the text file:

Out dated programs on the system are vulnerable to malware.
Please update or uninstall them:


Java 7 Update 51 <---this is OK

Uninstall all of these from your add/remove programs:
Java™ 6 Update 2
Java™ 6 Update 7
Java™ 6 Update 45


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 /


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)

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.

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.
If you think I've helped you, please leave a comment > click on my avatar picture > click Profile Feed.

Take a look at My Preventive Maintenance to avoid being infected again. (PM also found HERE)

Good Luck and Thanks for using the forum, MrC
