Memory usage too high after 4-5 hours work. In my case about 200MB. I got "swap file too small" warning. I kill the process .

Real Tech Wireless Lan driver - typically the one bundled with onboard adapters on certain MOBOs ... mine is an ASUS .. important to have the adapter working, but can be deleted if not using it.

Yes, it is for your wireless...remove it and you'll break your network connectivity
   
Bad behaving, but not a virus (scanned with Avast). Like the other poster, after a certain amount of time (within 24 hrs), resources used up, causing highlighted desktop icons, disappearing taskbar icons, disappearing start menu and memory errors when trying to execute programs, even task manager.
  Bill  
You can install the driver without this annoying utility.

Wasn't detected and removed until after a windows update. It came from a folder for my EnGenius usb wlan adapter. Network still works without it.

Best practices for resolving RtWLan issues

A clean and tidy computer is the key requirement for avoiding problems with RtWLan. 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 doing a repair of your installation, or in the case of Windows 8, 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 RtWLan.exe 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.
