windows defender error code 0x80244019


Thank you for your help its greatly appreciated

Hello Verrego,

This error is sometimes related to a Trojan Virus. I would recommend that you run a very thorugh antivirus and spyware scan to be safe. This may also be of help with this.

Unexplained computer behavior may be caused by deceptive software

Hope this helps,

the antivirus program i was using avg didn't catch it and ive tried downloading others and they didnt work either so i am not sure which is the best one to use.... ???

You might give the free Spybot S&D a try to see if it can find anything.

Sorry to bring this thread back from the grave. But I have merely joined to search and destroy this problem of mine. I found this thread on google as the top result. So I assumed it must be the most recent on this topic. As well as it talking about exactly my issue.

I too have the same problem as the Original Poster. It's really annoying because everytime I try to run the .exe to install any free anti virus it gives me this message..

'C:\Users\Steven\Desktop\Spybotsd162.exe is not a valid Win32 application.'

Does anyone know a way around this so that I can clear this thing out.

As well as this I tried to clear my HOSTS using the Notepad method and in my Windows Defender history, it says that the removal of the 'SettingsModifier:Win32/PossibleHostsFileHijack' was sucessfull. However I still can not update my Windows. Nor my Defender and I still have the signs that it is there.

Help please?

Have you tried any on-line scanners, like ESET or Kaspersky?
You could also test if the Malicious Software Removal tool finds anything. Type MRT.exe in the search field and run as admin.

Thank you for the reply. I have now tried all three..

ESET gives me a page load error.

Kaspersky wont load properly..

And as I try to launch Mrt. as an Admin, it immediatly says that it has to close. And shuts itself down..

I went into, as eariler suggested in the thread the manual remove programs tool. And came across CiD. An add-on that comes with Msn Live Plus 4.8. The CiD reference is always in the title of the browser pop-up when I get them. And the problem only started after downloading that. However... after removing the program and rebooting.. the error still occurs..

It would seem you have some kind of virus. I have no more time tonight, but other people may come and help you. Otherwise I will have a go tomorrow. It now depends on how advanced this bug is. I would suggest some easy steps first:

1. Disable all add-ons in Internet Explorer (Tools, Internet Options, Programs, Manage Add-Ons). Try running the on-line scanners again. Here is an additional one.
2. Reboot into Safe mode. Try MRT and whatever antivirus program you have installed from safe mode.
3. Download the Hijackthis executable (bottom link). Place it on your desktop and rename it to Analyze.exe. Run it first from Safe Mode, and then from normal. Then rename it back to HijackThis.exe and, once again, run it first from Safe Mode, then from normal. When you run it, follow the following parts of the Quick Start Guide: Do a System Scan Only and then Save log to desktop. Do nothing else, as it may harm your computer. Make sure you know which log is which. I am not a specialist on this, and I am unlikely able to help you analyze the logs. Other people can. What you can do yourself, is look for odd things, and compare logs with Analyze.exe and HijackThis.exe. Viruses not seldom try to trick HJT but may be tricked themselves if you rename it. You can also upload one of the logs for someone experienced to look at. Then upload as attachment.
4. You might try Easy Clean. BUT: Read the FAQ first, especially understand the risks with having the program automatically removing infected files, and then decide. If you are infected you may not have many choices. I hope you have a backup / working restore point.

1. I tried the first one, same result as before, I also tried it with Firefox. And the same again.

2. After rebooting to safe mode. I located the Mrt but it still wouldn't load this time. Both running as Admin and not.

3. I tried to download the Hijack.exe. but even after renaming it, I was not able to run anything at all, same mode or not.. thanks to this error..

'C:\Users\Steven\Desktop\Analyze.exe is not a valid Win32 application.'

4. I will try this in the morning.

I am guessing that I have the Win32 Trojan Hijack Host Virus.. Everything I have heard about it so far seems to fit the bill, and even though it is not Pc threatening, it is annoying. I may consider going out and buying Norton Antivirus, but will this help?

Just to let you all know. My problem is fixed. I managed to find and run this little beauty. It worked like a charm and removed more problems than I knew I had.

I am indeed a happy man.
