I'm on my laptop, but it is our desktop that's infected. I have the Hijack This log, but haven't run the other programs yet because when I tried to register an account here while on the infected desktop, it redirected my browser before the registration could complete.

The desktop is showing a new program called "Additional Guard". It is a fake antivirus-type program that has disabled my McAfee Online service, and it resists removal by Spybot S&D and Hijack This. I even tried manually deleting the hosts file, and was denied access. It would not allow me access to remove the "read-only" file attributes that the malware placed on the hosts file.

I'm obviously going to need someone to walk me through this process, as we have now exceeded my capacity on attempting to remove this malware. Many thanks in advance for your technical assistance!

The malware is preventing me from running either the DDS or RootRepeal on the infected computer. When I tried downloading directly from the link, the malware redirected my browser. When I tried transferring the files from a jumpdrive to the infected computer, neither is usuable. The DDS shows up only as a notepad file, and the RootRepeal simply will not install.

The "Additional Guard" program installed an icon on the desktop, which leads to a file in Documents and Settings/All Users/Application Data/39b4f5f named WI39b4.exe.

It is really grinding the desktop to a screeching halt -- it's not letting me do much of anything. I'm trying to run Spybot again to see what it is calling the remaining malware.

Ok, Spybot listed 3 items (one of which it was able to remove [again], but it will come back again -- attempted removal of the other two results in the error message "Cannot create file C:Windows/System32/drivers/etc/hosts. Access is denied"):

Fraud.WindowProtectionSuite
Win32.Delf.uv (this is the one Spybot can remove, at least temporarily)
Microsoft.Windows.RedirectedHosts


Spybot had no information about what the WindowsProtectionSuite malware does, or where it resides on the computer. Spybot indicated that for the Delf program, that it is known to hide the various files in the Fonts folder, but I looked and saw nothing other than fonts (and I have the system set to see hidden files). I've already posted above about the access problems with the Hosts file.

Hope this provides a bit more info that is useful.

Welcome to the BleepingComputer Forums.

Since it has been a few days since you scanned your computer with HijackThis, we will need a new HijackThis log. If you have not already downloaded Random's System Information Tool (RSIT), please download Random's System Information Tool (RSIT) by random/random which includes a HijackThis log and save it to your desktop. If you have RSIT already on your computer, please run it again.
  • Double click on RSIT.exe to run RSIT.
  • Click Continue at the disclaimer screen.
  • Please post the contents of log.txt.
Thank you for your patience.

Please see Preparation Guide for use before posting about your potential Malware problem.

If you have already posted this log at another forum or if you decide to seek help at another forum, please let us know. There is a shortage of helpers and taking the time of two volunteer helpers means that someone else may not be helped.

Please post your HijackThis log as a reply to this thread and not as an attachment. I am always leery of opening attachments so I always request that HijackThis logs are to be posted as a reply to the thread. I do not think that you are attaching anything scary but others may do so.

While we are working on your HijackThis log, please:
  • Reply to this thread; do not start another!
  • Do not make any changes on your computer during the cleaning process or download/add programs on your computer unless instructed to do so.
  • Do not run any other tool until instructed to do so!
  • Let me know if any of the links do not work or if any of the tools do not work.
  • Tell me about problems or symptoms that occur during the fix.
  • Do not run any other programs or open any other windows while doing a fix.
  • Ask any questions that you have regarding the fix(es), the infection(s), the performance of your computer, etc.
Thanks.
