The Solution Rating System

With so many solutions, how can you tell which solutions are most likely to help you and which ones are not? To provide you with a tool to use, we rate our solutions based on various elements that most accurately determine if a solution is a quality solution. To explain what factors affect the solution rating, here are the elements we take into consideration when formulating our solution rating.

  • The Grade of the Solution
  • The Zone Rank of the Expert Providing the Solution
  • The Number of Author and Expert Comments
  • The Number of Experts Contributing
  • The Feedback of the Community

Your Input Matters
Because of the way the system is set up, the most important variable in this equation is you. As a member of Experts Exchange, you are able to cast your vote on the quality of the solutions in regard to how complete, accurate, helpful and easy to understand each solution is. When you provide your feedback, each rating is adjusted accordingly. So, if you see a solution that has a poor rating that you think is a good solution, let us know by rating it. As you do, the rating will be adjusted and will become more accurate for other members of our site.

If you have any suggestions that you would like to make for our rating system, please ask a question in the Suggestions Zone of Community Support.

Thank you!

Combofix says null.sys is missing, is this a problem and where can it be restored from?

Asked by Jsmply in Windows XP Operating System, Anti-Spyware, Windows Network Security

Tags: Windows XP Pro

Hi everyone,

Combofix was recently run on a workstation as a follow-up to MBAM finding some minor spyware infections.  Combofix didn't end up deleting anything, but it does report the following that is somewhat alarming:

"c:\windows\system32\drivers\null.sys . . . is missing!!"  

Is this a problem?  When the machine first boots up it telle ms that "To Help protect your computer, Windows has closed this program" and that program is Generic Host Process for Win32 Services."

Once clicking "Close Message" the machine seems to act just fine.

The combofix log is attached.  I only have remote logmein access to this workstation right now so if there are any repair suggestions, please keep that in mind.

Thanks!
