User Comments

The RegGet! plugin for MSIE, RegGet is a download accelerator. So: not dangerous ;)
Seems to monitor surfing to add any DL's to ReGet. Seems harmless but could be used as exploit.
no problem only use reget is a accelerator
it installs several spyware programs on your computer on startup
Monitoring and/or 'catching' of entered URLs is an optional component of Reget downloader. You can disable this option through Reget preferences menus. If this "spy" disabled (as mine is), it should not need to be in the process list at all.
File that is used for ReGet. When clicking on a download link in your internet-browser this file will start the ReGet download utility

Best practices for resolving Catcher issues

The following programs have also been shown useful for a deeper analysis: Security Task Manager examines the active Catcher process on your computer and clearly tells you what it is doing. Malwarebytes' well-known anti-malware tool tells you if the Catcher.dll on your computer displays annoying ads, slowing it down. This type of unwanted adware program is not considered by some antivirus software to be a virus and is therefore not marked for cleanup.

A clean and tidy computer is the key requirement for avoiding PC trouble. 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.
