remove arp 1394

I am using Prevx3.0 and it cannot remove this malware. I am also unable to download any new software to try and get rid of the problem.

Please download the current version of HijackThis from HERE

• Double click and run the installer.
  
• It will install to C:\Program Files\Trend Micro\HijackThis\hijackthis.exe
  
• After installing, you should get the user agreement, press accept and Hijack This will run.
  
• Select Do a system scan and save a log file. This will open a notepad file of everything Hijack This found, copy and paste it back here.
  

When I try to download this, I get an error that application is not found.

A screen opens that says Open with. I am choosing Internet Explorer. The forospyware opens, but it is blank.

Hello.

Please download exeHelper

• Double-click on exeHelper.com to run the fix.
  
• A black window should pop up, press any key to close once the fix is completed.
  
• Post the contents of log.txt (Will be created in the directory where you ran exeHelper.com)
  

Note: If the window shows a message that says "Error deleting file", please re-run the program before posting a log - and post the two logs together (they will both be in the one file).

Can you run Hijack This now?

It still says application not found when I try to run Hijack

Delete it and re-download it via my provided link.

I am unable to add or remove any programs. Is there a file I should be looking for?

I get c:\windows\system32\rundl32.exe application not found when I try to add or remove anything.
