winupd.exe ist ein Keylogger. Der standard-Browser (z.B. Firefox) wird als unsichtbarer Prozess gestartet und zur KOmmunikation genutzt. Die Keylog-Datei liegt im selben Verzeichnis wie winupd.exe, unter dem Namen winupd (ohne Dateiendung)

remane file and add .avi. It then becomes an AVI file. I have used this method for a month or so with no ill effects and no pain in the butt popups.
Winupd.exe mit Größe 76 KB (bei mir im Ordner .../system32) ist ein gefährlicher Keylogger. Dateien werden in Datei "winupd" (ohne Endung) abgelegt.

Winupdate wurde von meinem Scanner als Virus erkannt. Habe ihn sofort entfernt, scheint aber immernoch da zu sein. Bitte um Hilfe.
Mit sicherlich eine Malware, bei jedem löschversuch taucht es nach einigen sekunden wieder auf und verlangsamt meinen Pc. Es ist zu 80 % schädlich
beim mir kommt beim Starten des Pc ob ich dieses Teil starten will, also ausführen wusste nicht was ich machen soll weil ich dachte es gehört zum system habs jetzt aber gelöscht xD
If is in temp, then remove! It has a lock-key icon! It's spyware/virus.

Best practices for resolving winupd issues

A clean and tidy computer is the key requirement for avoiding problems with winupd. 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 winupd.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.
