A question about my HiJackThis log.

I am using Windows Vista Home Premium and I ran the HiJackThis program. In my log, under the items with the prefix number 023, I show many files that either have "unknown owner" or (file missing) in the entry. All of the entries with (file missing) are in the system32 folder, but they are actually there. Why would the HiJackThis log show them as missing? Most of these files have both "unknown owner" and (file missing) within the same entry. What owner are they referring to? I am trying to make heads or tails with these entries. I picked these entries because a couple of the HiJackThis Log analyzers on the Internet advised me to fix or delete these entries. But I am very hesitant in doing this until I can get more information. Thanks

Hi,

HiJackThis is pretty long in the tooth method in computer terms. The entries are probably left
over from uninstalls, updates, and possibly remnants of malware removal.

If you need to check for malware here are my recommendations - these will allow you to do
a thorough check and removal without ending up with a load of spyware programs running
resident which can cause as many issues as the malware and maybe harder to detect as the
cause.

No one program can be relied upon to detect and remove all malware. Added that often easy
to detect malware is often accompanied by a much harder to detect and remove payload. So
its better to be overly thorough now than to pay the high price later. Check with these to an
extreme overkill point and then run the cleanup only when you are very sure the system is clean.

These can be done in Safe Mode - repeatedly tap F8 as you boot however you should also run 
them in regular Windows when you can.

Download malwarebytes and scan with it, run MRT, and add Prevx to be sure it is gone.
(If Rootkits run UnHackMe)

Download - SAVE - go to where you put it - Right Click on it - RUN AS ADMIN

You're very welcome, gilloz.

I'm glad to hear that you're currently experiencing no problems with your computer.  

For your future reference, avoid loading up your computer with multiple security programs that run in real time rather than on demand.  One good anti-virus product and one good anti-malware product, in conjunction with the Windows firewall, and along with safe-surfing habits, should provide more than ample protection for your computer.

Protect your computer by keeping your installed programs updated to avoid security vulnerabilities.  I highly recommend a monthly scan with Secunia's free Online Security Inspector   to help detect programs on your computer that are in need of patching and/or updating.  Keep your Windows Vista operating system updated by installing the monthly updates provided by Microsoft.  An unpatched operating system will make a computer a prime target for malware.

Avoid so-called "registry cleaners" that promise to speed up your computer by cleaning up and optimizing your registry.  Your registry doesn't need cleaning and is best left alone.  Registry cleaners are unnecessary and have the potential to cause serious problems by removing something that should not be removed.
