Hi all, I have been reading posts and help topics here at bleeping computer and Majorgeeks.com. I have the vundo trojan as well as what mcAfee calls Spy-agent.bw.gen.e and some variants of both. I am running various scanner/removal tools in normal mode (with system restore off) because the trojan will not let me run in sany variety of safe mode. I first ran mcAfee, emptied quarantine and recycle bin files, then cCleaner, then superantiSpyware, then Hijack this, and am currently (after much much troubl) running malwarebyte's Anti-malware. Each program is finding files.

With each of the above mentioned free programs, I have felt comfortable because there are cnet reviews and other sites that review the programs and make me think they are safe and not actual malware itself.

However, with respect to combfix-all I see when I research it is that its really difficult to run properly and an inexperienced user can really screw their computer up. Has anyone used it, is it too complex for a beginner? What are the risks?

With respect to MGTools- I found two review websites that say its malware itself. Does anyone know anything about this program? Have you used it? was it helpful?

I cant find anything about rootrepeal- any suggestions?

THANKS!!!

As no logs have been posted, I am shifting this topic from the specialized HiJack This forum to the Am I Infected forum.

==>PLEASE DO NOT NOW POST LOGS<== unless a log is specifically requested.

ComboFix is an extremely powerful and specialized tool which should only be used when instructed to do so by someone who has been properly trained. ComboFix is intended by its creator to be "used under the guidance and supervision of an expert." It is NOT for general public or personal use. Please read Combofix's Disclaimer. Using this tool incorrectly could lead to disastrous problems with your operating system such as preventing it from ever starting again.

Running ComboFix by yourself is like performing open heart surgery on yourself--the scalpel and other surgical tools that is ComboFix is meant to be wielded by a highly trained surgeon only in emergencies or dire circumstances. When the surgeon is thru s/he leaves the room. So combofix should be removed from a system once it has accomplished its job, unlike an AV that is there to protect you from future infections.

. . . CF does make some alterations to your system if you run it. Even if you had no malware removed and run the uninstall command, some things may be different now on your system. I can tell you that one thing is that all your restore points will be flushed out and a new one created. There is a good reason to do that when you have a severe infection--but if you aren't infected you might need those restore points.

Read and abide by the disclaimer people. It's there for a reason. Stick to running and protecting yourself with a good AV and firewall and an anti-malware scanner or two. If you feel you need a second opinion, try running online scans. If you feel you might need surgery, come here to BC and ask for help--that is what we're here for.

I am running various scanner/removal tools in normal mode (with system restore off)


Disabling System Restore as the first step when attempting to clean a system or when scanning for malware is not advisable. Unfortunately, some anti-virus vendors still recommend doing this before attempting malware removal and many folks follow that advice. This is really not a good practice when dealing with infected computer systems. Turning System Restore off and then turning it back on has some risk associated with it since that feature does not always work as intended. Further, there is always a possibility of something going wrong during the malware removal process and you end up with more problems. If an incident renders your system problematic or unbootable, you can use System Restore to return it to a previous working state. Without a restore point to fall back on, you are left with a limited means of restoring your system to a usable condition. Disabling this feature could mean having to perform a repair install (or reformat in worst case scenarios) if you're unable to fix any problems which System Restore may be able to correct. Although System Restore is not always 100% guaranteed to work all the time, it at least gives you another option before resorting to more drastic measures.

"System Restore and malware removal - what is best practice?"
"Should I purge all my restore point BEFORE removing infection?"

Please provide more details about the issues your computer is experiencing.
