I have been looking for a solution for two months

I receive the same error, whenever I try to start any scan ..

An Error Has Occurred
Her are the problem details:
-Error Starting on Demand Scanner

When finished, you will return to the Home window.

I have been searching for a solution since that time and found nothing.

I think that it has something to do with IE.
This is what I found in other forums, but I tried there solutions and nothing worked.

RE: I have been looking for a solution for two months

basketbal, I am having the exact same issue as you. I'm positive it is a virus because prior to the issue, McAfee detected/blocked a few trojans and then my computer did an automatic restart. Upon restart, there was an icon on my toolbar (obviously fake) saying "Windows has detected spyware! Click here to clean up your spyware!" if Microsoft would really use exclamations in their alerts...

I tried to do a scan and gives me the "Error starting on demand scanner". I click on links in ie and get redirected. I even ran Virtual Technician and it says my system is fine. Has anyone found a solution yet?

I too have this problem

Some symptoms I am seeing (either associated with this problem or something else),
1) A new user was installed on my computer, I have since deleted the user, but still have another user called guest, not activated (whatever that means)
2) IE will not launch the error "Windows cannot access the specified device, path, or file. You may not have the appropriate permissions to access the item" Trying to re-install IE has failed
3) Firefox browser works though
4) Prior to IE failing completely, Google had an interesting change in character, after searching, I selected a site by clicking on the title link, and it redirected me shopping sites (not the site that was found). I could still navigate to the site of interest, by copying and pasting the site information into the address bar.
5) this google behavior has spread to Firefox.
6) h.exe has showed up in my Task Manager window, under processes. What it caused was an audio connection to advertising. I stopped the process, but eventually, it came back.

Unless this thread finds a solution to this McAfee problem soon, I am getting ready to drop the bomb on my OS, wipe and reload XP. I had just bought McAfee a few weeks ago, moving from Micro Trend Pro.... Hmmmm....

Thanks for any help all you smart people out there might have.

same problem

I am having the exact same problem this is obviously a virus. Can anyone help i am trying EVERYTHING!

Tried everything... keep trying

Well, I am continuing to try things...

There was a site I found that had recommended a combination of free cleaners (CCleaner, Malwarebytes' Anti-Malware, Super Antispyware free edition, HijackThis). Whatever is doing the bad things, it is good.

Malware was able to launch the first time, but when the scan started, it just stopped (window disappeared with no pop up). The next time I tried to launch it, you guessed it... the now famous "Windows cannot access the specified device, path, or file. You may not have the appropriate permissions to access the item"

SuperAntiSpy was able to run, and found many hundreds of issues and deleted them. When I went to run it again, you guessed it the more and more famous "... cannot access..."

HijackThis was never able to run, just the "...cannot access..."

It seems like anything looking for the virus is being disabled (permissions removed from the user to launch). If I knew more about how the permissions could be reset, then maybe I could find the process that is causing this... Maybe that is the next step to take, start deactiviating processes and see if any of them clean this up...

Stay tuned....

OK, I am getting closer to nuking the system and rewriting the drive... (when all else fails, punt)... but I am not quite ready to give up.


Now when i restarted my computer i have nothing on the screen just my background picture, no icons, ill try safe mode and see what happens, at this point i just want to be able to burn all the family pics off of it and punt even though its only third now and 55 yards to go.

RE: ouch

Download Hijackthis and post its log on one of the following forums for expert advice.

I only just noticed this thread as the minute someone hijacks someone else's thread it goes off our radar...we don't see it as an unanswered post any more. In future folks please post your own new threads.

Also moving this thread to Virus Discussions & Removal Assistance as a more appropriate spot.


Do not post the log here, we can't help!
