FreeFixer is a general purpose removal tool which will help you to delete potentially unwanted software, such as adware, spyware, trojans, viruses and worms. FreeFixer works by scanning a large number of locations where unwanted software has a known record of appearing or leaving traces. The scan locations include the programs that run on your computer, the programs that starts when you reboot your computer, your browser's plug-ins, your home page setting, etc.
FreeFixer does not know what is unwanted, so it presents the scan result and it's up to you decide if some file should be removed and if some settings should restored to their default value. Please be careful! If you delete a legitimate file you may damage your computer. To assist you when determining if anything should be removed you can find more information at FreeFixer's web site for each item in the scan result. You can for example see what other users chose to do in the same situation. You can also save log file of your scan result and consult the volunteers in one of the FreeFixer helper forums.
For more detailed information about FreeFixer, please see the User's Manual.
Download FreeFixer here. FreeFixer is freeware and Windows 2000/XP/2003/20008/Vista/7 RC1 compatible. 64-bit Windows is not supported yet.
Screenshot showing some of FreeFixer's scan result. Files listed with green background
are on FreeFixer's list of trusted files. The files with white/gray
background are unknown to FreeFixer, so it cannot say anything about them. (In this
case, they are all legitimate files).
When FreeFixer is unable to delete files in normal Windows mode they
are registered for delayed removal with FreeFixer's Native Deleter,
which removes the files upon the next reboot. The actual delete operation
is done before the logon screen appear. The majority of malware can be deleted at
this point.
The summer has finally arrived here in Sweden. Now is the time to go swimming, bouldering and do all the other things that requires great weather.
As you may know, I've been documenting lots of drive-by downloads and intend to continue doing so during the summer. To make this as smooth as possible I've set up this blog post which I'll update when I find some new malware that use security holes to install.
As usual, I'm scanning the infected system with FreeFixer to find out what's been installed on the system. I'm also using FreeFixer to remove the unwanted files.
Another nasty infection. The files msjv32.dll and msne.exe was hidden from detection by a rootkit:
c:\windows\system32\msjv32.dll C:\Documents and Settings\Roger\Skrivbord\msdos.pif c:\windows\system32\msne.exe
C:\WINDOWS\9129837.exe c:\windows\system32\drivers\securentm.sys C:\WINDOWS\System32\rr64_b.exe HOSTS file redirecting safesystem.microsoft.com to 209.44.111.62 HOSTS file redirecting antiviraprof.com to 209.44.111.62 HOSTS file redirecting www.antiviraprof.com to 209.44.111.62
Nasty little bugger. None of the 40 anti-virus engines over at VirusTotal.com detects HB32.dll:
C:\WINDOWS\system32\wbem\HB32.dll
C:\WINDOWS\system32\EVA.exe C:\DOCUME~1\Roger\LOKALA~1\Temp\init.exe C:\DOCUME~1\Roger\LOKALA~1\Temp\3.EXE c:\windows\system32\drivers\systemntmi.sys C:\Documents and Settings\Roger\Application Data\twex.exe C:\Documents and Settings\Roger\Start-meny\Program\Autostart\rncsys32.exe C:\WINDOWS\ld09.exe C:\WINDOWS\System32\net.net
This drive-by download installed the System Security Rogue, Koobface, and a malware device driver:
C:\windows\ld11.exe C:\Documents and Settings\All Users\Application Data\15452184\15452184.exe c:\program\sys\sys.sys
A device driver + additional malware:
C:\WINDOWS\System32\drivers\ethxhkrw.sys C:\WINDOWS\System32\sdra64.exe C:\WINDOWS\system32\logon.exe
About three weeks ago Avelino Rico Jr over at McAfee Labs blog reported about a new rogue security program called Malware Doctor.
This morning my honeypot caught Malware Doctor and some additional malware installing by exploiting a security. I've pasted the FreeFixer log and marked the malware item in red:

For the last three days I've been experimenting with a new FreeFixer plugin. The plugin simply lists the most recently modified/created files, which appear at the end of the scan result. Definitely no rocket science, but in a case of a malware infection, I think it can be quite efficient in pointing out the unwanted files.
I've tested the new plugin on some real world infection picked up by my malware honeypot. All the unwanted files listed in the scan results were installed through security holes. I've marked them with red. During the testing I also ran into Antivirus System Pro, which is another of those rogue anti-spyware programs. Antivirus System Pro uses sysguard.exe as its file name and is located in the c:\Windows folder. You can find more information and screenshots on this rogue over at Bharath's Security Blog.

I'm obsessed with looking at the traffic stats for FreeFixer.com. About halfway into June shows some new filenames among the top searches:
A couple of weeks ago a new rogue security application appeared. Here's a FreeFixer log from the infected machine. I've marked the Presto Tuneup file with red:
