I have an unknown virus or malware program on my laptop. I cannot write to certain files. Ran Hijack This and got this message "For some reason your system denied write access to the Hosts file. If any hijacked domains are in this file, Hijack This may NOT be able to fix this. If that happens you need to edit the file yourself...." It then went on how to do this.


Ran Malwarebytes - no issues

Ran Superantispyware; just a bunch of cookie files

Ran Hijack This as mentioned above

Currently running an Adaware scan (which is taking forever) and a Roguekiller scan - still running as well.


Any help/advice is appreciated. I would prefer not to have to re-install operating system.

Are you able to view documents such as...pictures, data files, videos, etc. ?


Don't post results of Hijack This, Adaware scans or Roguekiller scans in this forum.


You may have a security program blocking access to the host file. I think Winpatrol does that for one.

Not sure if Spybot does or not. Do you have either of those programs installed?


See if you can replace the host file contents.

Replace your current HOSTS file with a tweaked one, as the MVPS Host file, that restricts access to known bad sites improving your security.
It basically prevents your computer from connecting to those sites by redirecting the attempted connections to, which is the IP of your local computer.

To do it:

  • Download hosts.zip and save it to your desktop
  • Right click the file you just downloaded on your desktop and select => Extract to "hosts\"
  • In the hosts folder on your desktop, double click on mvps.bat file to run the program
  • A prompt will appear, press any key to continue

Use the programs below to clean, remove malware and remove adware.


Use CCleaner to remove Temporary files, program caches, cookies, logs, etc. Use the Default settings. No need to use the

Registry Cleaning Tool...risky. Pay close attention while installing and UNcheck offers of toolbars....especially Google.

After install, open CCleaner and run by clicking on the Run Cleaner button in the bottom right corner.

CCleaner - PC Optimization and Cleaning - Free Download


Download AdwCleaner by Xplode onto your desktop.

  • Close all open programs and internet browsers.
  • Double click on adwcleaner.exe to run the tool.
  • Click on Scan button.
  • When the scan has finished click on Clean button.
  • Your computer will be rebooted automatically. A text file will open after the restart.
  • Please post the contents of that logfile with your next reply.
  • You can find the logfile at C:\AdwCleaner[S1].txt as well.
  • download Junkware Removal Tool to your desktop.
  • Shut down your protection software now to avoid potential conflicts.
  • Run the tool by double-clicking it. If you are using Windows Vista, 7, or 8; instead of double-clicking, right-mouse click JRT.exe and select "Run as Administrator".
  • The tool will open and start scanning your system.
  • Please be patient as this can take a while to complete depending on your system's specifications.
  • On completion, a log (JRT.txt) is saved to your desktop and will automatically open.
  • Post the contents of JRT.txt into your next message
  • Hold down Control and click on this link to open ESET OnlineScan in a new window.

  • Check "YES, I accept the Terms of Use."
  • Click the Start button.
  • Accept any security warnings from your browser.
  • Under scan settings, check "Scan Archives" and "Remove found threats"
  • ESET will then download updates for itself, install itself, and begin scanning your computer. Please be patient as this can take some time.
  • When the scan completes, click List Threats
  • Click Export, and save the file to your desktop using a unique name, such as ESETScan. Include the contents of this report in your next reply.
  • Click the Back button.
