temporäre dll für mouse wheel utility freewheel.exe

Extremely useful , small harmless application.

Mcafee virusscan blocked this file which was created by starting Outlook! Probably installed by freewheel mouse utility, (can be frw3.tmp or frwX.tmp too) I am not sure why, and if this is harmless.
Process frw1.tmp does not terminate when freewheel is exited. This program is highly suspect.

This is the hook DLL for FreeWheel, a mouse utility that I wrote many years ago. It is not harmful in any way. I did not foresee that virus scanners would block DLLs loaded from the temp directory. If the DLL stays loaded after exiting FreeWheel, that is due to Windows itself and is outside of FreeWheel's control. In fact, FreeWheel keeps track of any temp files it creates and will try to delete them the next time it is run.

Best practices for resolving frw1 issues

A clean and tidy computer is the key requirement for avoiding problems with frw1. This means running a scan for malware, cleaning your hard drive using cleanmgr and sfc /scannow, uninstalling programs that you no longer need, checking for Autostart programs (using msconfig) and enabling Windows' Automatic 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 resmon 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, for Windows 8 and later versions, executing the DISM.exe /Online /Cleanup-image /Restorehealth command. This allows you to repair the operating system without losing data.

To help you analyze the frw1.tmp process on your computer, the following programs have proven to be helpful: Security 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. Malwarebytes Anti-Malware detects and removes sleeping spyware, adware, Trojans, keyloggers, malware and trackers from your hard drive.
