BleepingComputer.com: Need help with Rootkit.ZeroAccess and TR/Crypt and others

Hi Agent ST,
I had alot of web dev work to catch up on this weekend because, as you know, I lost at least a week dealing with my own machine....so it's taken me this long to mosey into the other room and see about my husband's computer.

I ran the defogger to re-enable the CD stuff. Seemed to go smoothly.


Here's the OTL fix log:

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

I've got a very busy two days coming up at work (Mon-Tues) but I will try my best to get back here Tuesday night / Wednesday afternoon at the latest.

Thanks for hanging in there with me all this time! :-)

Am I going to need to re-install Windows on this machine, format the hard drive, etc. when we're done to ensure that it will be 100% secure again?

Is Rootkit.ZeroAccess finally gone?

Thanks, Dona

Hi Dona!

No worries!

Okay, not a problem!

Yes, the only way you can guarantee that this computer is 100% clean and secure would be to reformat and re-install the operating system.

From what I can see, yes it appears to be gone, but see above response.

All Clean Speech




Below I have included a number of recommendations for how to protect your computer against malware infections.


Updated Anti-Virus Program
It's essential that you have an updated anti-virus program running on your computer. You don't want to run more than one as it can cause program conflicts, as well as false positives

You can view an excellent list of Free Security Software programs that has been compiled by GeekstoGo.


Avoid P2P Programs

Remember that no matter how clean the program you're using for peer-to-peer filesharing may be, it offers no guarantees regarding the cleanliness of files you may choose to download. All files available via p2p filesharing carry a high risk, particularly those that offer you illegitimate methods of using legitimate software programs without paying for them. Some further readings on this subject, along the included links, are as follows: File-Sharing, otherwise known as Peer To Peer and Risks of File-Sharing Technology.

If you have any of these programs installed then I highly suggest you uninstall them.

NOTE: Take care when answering any questions posed by an uninstaller. Some questions may be worded to deceive you into keeping the program.


Internet Browsers

Many of the users that I assist here on the forums, ask me which programs they can use to prevent themselves from getting infected again in the future. The best answer I can give you is too practice safe browsing.

Please consider using an alternative browser such as Google Chrome or Opera. They are both much more secure than Internet Explorer, immune to almost all known browser hijackers, and also have great built-in pop-up blockers.

I also suggest you make your Internet Explore more secure.



Extra Goodies

• It is good security practice to change your passwords to all your online accounts on a fairly regular basis, this is especially true after an infection. Refer to this Microsoft article
  Strong passwords: How to create and use them then consider a password keeper, to keep all your passwords safe.
  
  
• Keep Windows updated by regularly checking their website at: http://windowsupdate.microsoft.com/
  This will ensure your computer has always the latest security updates available installed on your computer.
  
  
• You should run an updated scan with MalwareBytes' Anti-Malware weekly. Instructions are included below:
  
  
  • Open Malwarebytes' Anti-Malware
    
  • Select the Update tab
    
  • Click Check for Updates
  
  
  
• Be weary of e-mails from unknown senders. Keep the following in mind as well: If it's to good to be true, then it more than likely is.
  
  
  
• FileHippo Update Checker is an extremely helpful program that will tell you which of your programs need to be updated. Its important to keep programs up to date so that malware doesn't exploit any old security flaws.
  
  
• WOT, Web of Trust, warns you about risky websites that try to scam visitors, deliver malware or send spam. Protect your computer against online threats by using WOT as your front-line layer of protection when browsing or searching in unfamiliar territory. WOT's color-coded icons show you ratings for 21 million websites, helping you avoid the dangerous sites:
  • Green to go
    
  • Yellow for caution
    
  • Red to stop
  WOT has an addon available for Chrome and Opera.
  
  
• Keep a backup of your important files - Now, more than ever, it's especially important to protect your digital files and memories. This article is full of good information on alternatives for home backup solutions.
  
  
• In light of your recent issue, I'm sure you'd like to avoid any future infections. Please take a look at these well written articles:
  
  Think Prevention.
  PC Safety and Security--What Do I Need?.

**Be very wary with any security software that is advertised in popups or in other ways. They are not only usually of no use, but often have malware in them.

Thank you for your patience, and performing all of the procedures requested.

Please respond one last time so we can consider the thread resolved and close it, thank-you.

Cheers,
SweetTech.

Hi Agent ST

Just did the clean up activities.
Here's the last OTL file:
========== COMMANDS ==========
Restore points cleared and new OTL Restore Point set!

OTL by OldTimer - Version 3.2.31.0 log created on 02222012_161553

Of course I'll need to turn on System Restore and create a restore point when I get done blasting this computer but I did it anyway because you asked. :-)

I've reinstalled Windows on these Dell's a few times over so it's not a problem at all, I just need to find the time.
When I'm done with that, I'm giving my husband instructions to only use Google Chrome with the WOT plug-in (sounds good) for browsing and weekly scans with Microsoft Security Essentials and Malwarebytes.

I also uninstalled Combofix. Is that just a routine thing you have people do because most people don't know how to use it? Just wondering...
I have it on my thumb drive if I need it in the future anyway.

and Last, Do you personally use the FileHippo or KeePass extras you mentioned? They sound like a good ideas so just wondering if you use them too.

So, I guess I can't believe I'm actually going to be signing off with you on this!! I'm kinda sad...

Anyway...I certainly know where to come if I need virus removal expertise again in the future.

Thank you for taking such good care of me and walking me through all this stuff.

You are da MAN!!

Take Care and Best Regards, Dona

Hi Dona!

That sounds look a good plan!

It's really a combination of things. The main reason why we uninstall it once we are done with it, is because there are some Quarantine folders that should be removed once we are finished removing the malware, and removing ComboFix gets rid of those folders. The other reason is because ComboFix isn't a tool that should be used without supervision. If it's used inproperly, it can cause all sorts of issues, including a unbootable computer. Lastly, it's also a tool that's updated quite frequently, sometimes as often as a few times a day, so if you were to need to use the tool in the future, it'd be extremely outdated, and wouldn't work as effectively as it would have if it was the latest version.

I try and recommend utilities, that I use or have used on my own pesonal computer before. FileHippo is one of those tools, that I do have installed on my personal computer. It's a very useful tool.

In regards to KeePass see this response below, that I previously provided to a user I worked with recently in regards to a secure password manager:

I hope that information is useful, and if you have any questions about my response to your question, please let me know.
