Update about wupdater.exe for Window 7. The malware/spyware stucks Internet Explorer and FireFox browsers. Google Chrome is more safe for some protections but also compromised. The malware stucks also Second Life viewers. wupdater.exe is a malware by White Sea Media (do not visit the web page of it). The malware is allocated in: C:\Users\*name of user*\AppData\Local\Temp\wupdater.exe. The antivirus Avira Control Center does not find it as virus. You must put the exe file in quarantine but it is still in the unknow folder of registry. The subfolder Run, HKEY_LOCAL_MACHINE is not findable.
This is known as a RAT or Remote Administrative Tool; a Trojan installed on your computer which gives the hacker full access to your entire computer, settings, files, and more. Scan this with Spybot Search and Destroy, as its not damaging, but invades your personal Computer.

Best practices for resolving wupdater issues

The following programs have also been shown useful for a deeper analysis: Security Task Manager examines the active wupdater process on your computer and clearly tells you what it is doing. Malwarebytes' well-known anti-malware tool tells you if the wupdater.exe 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.
