Solve : Problems with installing apps in Windows 10 - Caused by the Trojan wlanext.exe?!? |
|
Answer» Hello Folks! - I've got this pretty tricky Windows 10 Problem. A few weeks ago I suddenly discovered that my PC got hot every time I had it logged online, so I opened the Task Manager where I saw that the processor was charged by as much as 35%!(AMD) although I only had a browser running. When I scrolled down the list of running applications I saw an unknown clown-like icon - the application was named wlanext.exe - I have not seen it before and had no idea what it was for. This application alone used about 25%! of the processor power. After reading a little about it here on the web, I have understood that I'm not the only one who has been visited by this clown. Some experts say that it's completely harmless, and others that it's not - it's a Trojan! and it should be removed. I have now also understood that it is completely harmless to have C/windows/system32/wlanext.exe present - but C/windows/wmu3/wlanext.exe is not! ...and it should be removed. Inside the wmu3 folder there's also another small application called ZeroConfigService.exe - it can also (after what I have understood) be removed - so just go ahead and remove the wmu3-folder and everything that's in it! What is quite disturbing here is that an updated Windows Defender did not give any notice about the fact that these applications were present - and active! in the system! despite, several thorough runs. Is this something Microsoft has approved?- or are they in on this? ...I'm just asking However, another well-known applications did a great job - the intruders was quickly discovered and swept out! Now, after these applications have been removed, my computer is no longer a heat source in the house But I still wonder what they did here, where they've come from, and how they got in here. In my search for these invaders, I accidentally managed to PARTLY delete a small application. No big problem, I thought - I just have to remove the rest and do a reinstall, I have everything I need - the installer and otherwise all the other stuff I got sent when it was purchased ...installation code and sn etc. But it wasn't at all that simple. The application was reinstalled in the usual way, the registry dialog provided with a code/sn and user name - and then ...Hurray! it was up and running! Now everything seemed to be back to NORMAL again. I closed it - but to be absolutely sure that everything was really back in order, I restarted it, just to discover that it was not - I only got a new dialog for registration! - covering the application interface. So I went through the same reg-stuff once again, with the same result ...and a few more times, but no, every time I had to enter code/sn and user name etc. to get it started - and when it did, it was neither as a DEMO nor a trial, but quite normal - just as it has always been. I then contacted the company I had bought the application from, and gave them the same story i have told here. From them the message was clear, everything I had done was absolutely right - now it should have run as normal. They offered generously to send me the latest version - but the result was still negative. Then I tried with another application, from another manufacturer, same procedure - but also here with the same negative result - it simply wouldn't let itself register! It now seems that applications installed before I got visited by wlanext.exe and ZeroConfigService.exe, WORKS perfectly normal. But now it's simply just not POSSIBLE to register installed programs! So I'm left with a bad feeling that this mess is what ZeroConfigService.exe and wlanext.exe have left behind - pretty badly done! I have very little desire to get started with a full new installation of the OS etc. - pretty bad experience with almost endless, forced and unstable windows 10 updates would be the main reason ...no wonder I have windows Update Stop! installed here. So it's with great thanks to all I welcome both thoughts and speculations around these problems ...and for what reason I ended up getting them - and of course, suggestions on what I can do to get this Windows 10 installation fresh again. Eric PS I have tried a little with the windows 10 tools - also, the registry have been checked and defragmented with the Windows 10 Manager. S O L V E D ! ...and thanx for helping out. |
