this file monitors keystrokes ,relays that info to remote server at startup & subsequently tells net zero what type of garbage to download to your system.May be more dangerous since exe exe clones IE then write protects malware . note:soon after i installed net zero, my ad-awere se& spybot s&d were corrupted!!! beware there are a couple more bad guys hidden in nz software
   
after uninstalling netzero & then trying to reistall it, got error message saying couldn't "write" file hook.dll, click abort to stop install, retry to try to write file again or ignore to skip file....clicked ignore and now on internet, not sure if it is important or not...need more info plz

Netzero plants the hook.dll in their package to monitor the customers!
  try run NIS and Netzero at same time  
It can be removed by Norton Antivirus
  Roberto   (further information)
I cannot claim to know that it is indeed dangerous, but I put it in quarantine and NetZero is still working. Therefore it can't be essential to the functioning of NetZero and is safe to remove.

hook.dll is commonly used to replace a certain if not all process of a targeted dll's memory on the fly. Correct me if i'm wrong. It can be dangerous (causing unwanted crash) or not (replacing memory hex for certain procedures).
  Gilgamesh  
it's VMware if you have VMware tool installed in a virtual machine
   
it's for proxyway
   
used for desktop enhancers (RKLauncher and more)
   
hook.dll is also part of Trust drivers for mice that have more than the standard 3 buttons. IT DOES keylog but in a legit way (it's required for the extra buttons on the mouse to work). If you are installing Trust drivers for a Trust mouse and has more than 3 buttons (inc Scrollwheel), this file may be flagged by your AV as a keylogger. Just allow the file.

its also part of a mouse configuration software which is able to use programmable Macro instructions

allows attackers to access your computer from remote locations

It's to activate the special buttons on the "TRUST Gamer Optical Mouse GM-4200, without this file located in C:\Windows\System32\Hook.dll, you can't use the special buttons, and it will give you a message. File has been checked @ Avast 'nd AVG, Says this file that used for the mouse isn NOT a Dangerous file, and won't harm your computer.

IOBit Advanced System Care rates Hook.dll as a Trojan, Its description is Infostealer.Bzup; risk level is critical and it resides in C:\Windows\System32\. ASC enttry during the Spyware Removal section of the program. There is just one thing that has me really concerned. I let the program (ASC) removethis item every time I scsan my computer, however, on the next scan (in as little as 5 seconds), Hook.dll is there one again. Is it because ASC cannot remove it or is it because it is immediately replaced on my computer? FInally, my computer seems to be working just fine.

Best practices for resolving Hook issues

A clean and tidy computer is the key requirement for avoiding problems with Hook. This means running a scan for malware, cleaning your hard drive using 1cleanmgr and 2sfc /scannow, 3uninstalling programs that you no longer need, checking for Autostart programs (using 4msconfig) and enabling Windows' 5Automatic Update. Always remember to perform periodic backups, or at least to set restore points.

Should you experience an actual problem, try to recall the last thing you did, or the last thing you installed before the problem appeared for the first time. Use the 6resmon command to identify the processes that are causing your problem. Even for serious problems, rather than reinstalling Windows, you are better off repairing of your installation or executing the 7DISM.exe /Online /Cleanup-image /Restorehealth command. This allows you to repair the operating system without losing data.

To get your computer running as fast as it did on day one, you can 8reset your PC. Your personal files will remain intact, but any programs you installed will need to be reinstalled.

To help you analyze the Hook.dll process on your computer, the following programs have proven to be helpful: ASecurity Task Manager displays all running Windows tasks, including embedded hidden processes, such as keyboard and browser monitoring or Autostart entries. A unique security risk rating indicates the likelihood of the process being potential spyware, malware or a Trojan.
