Editors' Review

+

Combofix is a freeware utility that scans your PC deeply for spyware and malware, especially in combinations. It's a powerful tool that can remove stubborn infections but also delete files you need, if you let it, so inexperienced users who run Combofix without expert guidance do so at their own risk. Used properly, it can clean your PC much more deeply than typical tools, free or not, and not just of malware but other junk, too. It finishes with a detailed log that reports each step.

Combofix is portable freeware that runs when you click its extracted program file. We disabled our antivirus and firewall software, as Combofix recommends. Most programs advise you to close everything before you install them, but Combofix means it, and it'll tell you if an open window or running process needs to end before it can proceed. The program also automatically backs up your settings and creates a System Restore point, which is reassuring.

Combofix is mostly automatic in operation. It scanned our system and started deleting files at a rapid pace. A look at the scrolling log reassured us: Combofix was throwing out hundreds of tiny JPEGs left over from an uninstalled app. Other cleaners (which shall remain nameless) had missed them, and we were pleased to see them go. Most scans take less than 10 minutes, but infected PCs may take much longer; ours was clean, thankfully. Finishing requires a reboot. Things seemed to load and run faster; an extra benefit of this deep cleaner.

"The ONLY Thing I Need To Scan For Problems:"

April 21, 2014  |  By In-Correct

 |  Version: Not Found

Pros

ComboFix Saved My Computer MANY Times While The Other Competing Scanners AND EVEN ANTI-VIRUS SOFTWARE Missed.

Cons

After restart it says "Do not load any programs until ComboFix has finished." What about the startup items?! If it is that important, then ComboFix needs to actually BLOCK the programs from loading until the log report appears.

And ...

IT KEEPS PUTTING INTERNET EXPLORER ON MY DESKTOP. IT MAKES THE DEFAULT BROWSER AND DOWNLOAD MANAGER SET TO INTERNET EXPLORER. I HATE INTERNET EXPLORER.

Summary

Other Scanners are useless. They either 1. Report the item removed only to have it REAPPEAR AGAIN. or 2. Report "no items were detected." Meanwhile ComboFix deleted the items permanently.

There is a warning that this is not meant for use without the guidance of skilled technical support. That is wrong. All the other competition needs this warning. I have had two other spyware scanners BLUE SCREEN OF DEATH just by clicking the "Scan" button. An Anti-Malware never removed the items. Sometimes it didn't even FIND any items. The Anti-Virus does nothing but SLOW DOWN my computer. I still have a Registry Cleaner, and I even have the MSE "Anti Virus and Anti Spyware" scanner but with Real Time Protection turned off. (This is required with ComboFix regardless) but I rarely use them. I use ComboFix regularly and I have not experienced any problems with it "destroying my computer". Also, I have Flash Player blocked and I also have Ad Blockers and Third Party Image blocked.

I recommend ComboFix to anybody. As long as you follow the instructions, and never turn off the computer while scanning, you should be fine. I have not had any issues except for the two "CONS".

If ComboFix did not exist, many computers would be dead.

"Wonderful and Effective!!!"

December 07, 2013  |  By ducktoes

 |  Version: Not Found

Pros

This program isn't for people who don't know what they're doing but I have found Combofix to work quickly and effectively on serious viruses and malware that nothing else could crack. It is not meant to be a complete solution. If you have a virus you can't stop, try it. Then you can run Malwarebytes and Superantispyware etc. to finish up. It is much better than reformatting which is often the only alternative. I've never known it to do the things some of these other people are complaining about and I've used it a lot. Hats off to sUBs and the other volunteers at Bleeping Computer who help a lot of people remove viruses for free. After you run it some of your programs might not work until you reboot. Combofix turns off programs (viruses are programs) just until it can remove the malware. After you reboot everything will go back to normal.

Cons

It doesn't yet work on Windows 8.

Summary

It has saved many a computer from being reformatted.

"Works great when used properly!"

November 27, 2013  |  By PureGNS

 |  Version: Not Found

Pros

When downloaded from BleepingComputer ONLY it will run as it was designed to do. Always refrain from downloading software from any 3rd party links.
I have used this program for years now on to many computers to count from personal to professional.

Cons

You must follow directions, and save vital information before running any software like this. People need to use common sense is all, and simply downloading a program and ignoring what others have already stated is ignorance only.

Summary

When used as designed it is a great lifesaver for many that want to keep their current setup as is minus the slow issues from possible malware/spyware/hijackers/etc......

"DO NOT USE THIS "PRODUCT" !!!!!!!!!!!!!!!!!!!!!!!!!!!!!"

October 29, 2013  |  By Leatherider_too

 |  Version: Not Found

Pros

Easy download

Cons

Combofix will:

1. Destroy all of your settings,

2. Shut down your Clipboard,

3. Delete the settings for and make inoperative your System Restore feature (you can't even access the feature console),

4. Lock other protective software such as System Protector (Systweak), Malwarebytes, the spyware feature of Advanced System Optimizer -- all three of which are Microsoft Gold Certified --

5. Your Microsoft Computer Management Console will become inoperative.

6. Make your Taskbar inoperative except for Quickstart and the clock . . . .

And this is just what I've discovered so far . . .

Summary

MALWARE, SPYWARE !!!! AND WHO KNOWS WHAT ELSE.

A PIECE OF CRAP THAT CNET SHOULD BE ASHAMED TO RATE "EXCELLENT"

Updated on Nov 3, 2013

HERE IS A POTENTIAL FIX:

Took a lot of searching and analysis, but here is the fix for XP USERS (don't know if it works for later Windows versions):

What Combofix does is delete data instructions from the XP Registry and in effect shuts down the Remote Procedure Call. I don't claim to be an e-geek, but the RPC is sort of a server through which many functions must pass in order for your PC to operate correctly. The initial information I dredged up (not from Microsoft.com which was virtually useless) is from Here:

http://www.blackviper.com/2002/10/28/i-disabled-remote-procedure-call-before-i-read-your-advice-and-my-computer-is-broke-what-do-i-do/

wherein the author instructs the user in the following manner:

"Boot into safe mode and install this registry patch. It will place RPC service back into automatic. After applying the registry fix, you should be able to boot normally.

This file contains only the "Start" key:

Go to FIRST REPLY . . .

Updated on Nov 3, 2013

The "RpcSs" service, this information is applied:
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\RpcSs]
"Start"=dword:00000002

Download File Name:
RpcRepair.zip ~ 288 bytes ~ Version .01 ~ October 28, 2002

If this does not fix the problem, you can attempt to reinstall Windows on top of the old installation. This usually repairs the OS, but keeps user data still accessible. However, I do not support such actions for obvious reasons and you will need to reapply all patches, driver updates and service packs.

Anything on this page is offered with zero guarantee. Back up everything vital."

This didn't work in my case but gave me an idea. I have an older Toshiba laptop that runs XP (not the Media Center I have on here) so with nothing to lose I opened the RpsSs there. It was full of instructions that simply didn't exist on the Media Center. A bit of Copy and Paste later and VOILA!! The Media Center came back to life!

"Works and works well."

October 01, 2013  |  By Fudd123

 |  Version: Not Found

Pros

Easy to use and thorough.

Cons

It didn't come with cake.

Summary

Gave such relief (again). I'm pretty sloppy when it comes to security. Put bluntly, I dont use any because 99 times out of 100 the security software causes more headaches than malware.

But theres eventually always that one time. So I do run some big name anti-malware. Combofix always finds and kills what my antimalware doesnt. It saves me from trying to manually hunt down the problem, usually severe, arcane ones and is my 'magic bullet' "big gun' when I am up against malware that's above my skill to remove otherwise.

I dont really know what it is or how it works, I just know it works better than anything else Ive used. And I am very grateful. Thank you, sUBs.

"Good and Bad!"

August 30, 2013  |  By jclemet

 |  Version: Not Found

Pros

Seems to have helped remove unwelcome files.

Cons

Did not eliminate the problem! Bad guys still on my computer. Using Windows and various permissions to track them down.... Did not keep me informed of progress other than a few numbers.

Summary

Overall, I don't think Combofix is that great.

"Worst of the worst"

May 02, 2013  |  By Childsplay10

 |  Version: Not Found

Pros

None at all

Cons

Salitiy virus, desperate developers, POTENTIAL TO DESTROY A COMPUTER

Summary

The developers and distributors of Combofix are mainly scam artists but are also considered desperate because they often release versions of corrupt Combofix software bundled with computer viruses, such as the Salitiy virus. People who installed Combofix earlier this year and last year become infected with the dangerous virus and Trojans. This software will also destroy a computer as it was not designed well.
