Now picks up HijackThis as an invalid add/remove item. :?


HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Uninstall\HijackThis\


Updated, downgraded to .394 & it crashes before loading... back to .399 again. :(

Could you post the contents of that key here?

I do not get an error on that key. It looks like this:

  • Windows Registry Editor Version 5.00



    "DisplayIcon"="C:\\Program Files\\HijackThis\\HijackThis.exe"

    "DisplayName"="HijackThis 1.99.0"

    "DisplayVersion"="1.99.0"

    "Publisher"="Soeperman Enterprises Ltd."

    "UninstallString"="C:\\Program Files\\HijackThis\\HijackThis.exe /uninstall"

    "URLInfoAbout"="http://www.spywareinfo.com/~merijn/"

Can you tell me how to post the contents of the key? It seems very complicated to right click in v2007.

Simply locate the key, click it, right click it, select Copy to clipboard > keys and entries and paste the contents here.


Or, just locate the key, click it and press Ctrl and C.


The fact that you must first click a key before you can right click it is something Microsoft has inventend, by the way, not us. The component that shows the Registry Cleaner's result tree is a standard Windows treeview component.

I'm sorry that you felt the need for the sarcastic comment.


I asked, because right clicking or CTR+C only produces this...


HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Uninstall\HijackThis\{KEY} : {KEY}


...which is much less information than Tullik provided in his previous post.


I am using a more recent version of HijackThis than Tullik.

Nick555,


I have the Trend Micro Hijackthis V2.0.2 installed on my Vista Premium system. jv16 399 does not want to delete the uninstall key (in aggressive mode). JFI :

I'm sorry, I wasn't trying to be sarcastic. Could you please use the RegEdit to verify the contents of the key?


To me, the Registry Cleaner's result suggest that the key is in fact empty, for some strange reason. And if it is an empty key then it can be removed from the Uninstall key.

Sorry, we encountered an error while displaying this content. If you're a user, please try again later. If you're an administrator, take a look in your Flarum log files for more information.

Got it!


Windows Registry Editor Version 5.00



"DisplayName"="HijackThis 2.0.0"

"UninstallString"="\"C:\\Tools\\HijackThis.exe\" /uninstall"

"DisplayIcon"="C:\\Tools\\HijackThis.exe"

"DisplayVersion"="2.0.0"

"Publisher"="TrendMicro"


Looks like the value for the "UninstallString" entry name contains some extraneous characters ... :

Does C:\Tools\HijackThis.exe exist?

So the red characters are unbalanced delimiters, not data. (?)

That's correct.

What I don't understand is why his "Windows Registry Editor Version 5.00" delimited the export in different way than my "Windows Registry Editor Version 5.00" …

You are right, I didn't notice this before, it's indeed strange.

I tried this with my computer, if I enter the data Nick555 sent to my registy and save some file as C:\Tools\HijackThis.exe it doesn't show in the Registry Cleaner.


When I removed the file HijackThis.exe the key is shown with the Registry Cleaner just as it should have.


So I can't reproduce the problem.

Using the "Windows Registry Editor Version 5.00" posts in this thread, I replaced the UninstallString in my key with that of Nick555. This showed (via eyeballing RegEdit) that the red quote marks in my prior post are data, but the red backslashes are delimiters (and therefore, balanced). The matter was confusing since Microsoft's copy and paste suppresses the quote marks. The suppression happened both from the top of the Reg Cleaner window and from the RegEdit entry name Modify context menu popup. It appears to happen during the copy -- I "proved" this using Excel since copy and paste within a spread sheet did not suppress quote marks.


My UninstallString value: C:\Program Files\HijackThis\HijackThis.exe /uninstall

Nick555's UninstallString value: "C:\Tools\HijackThis.exe" /uninstall (just as jv said earlier)


But all that is not Nick555's problem. With the UninstallString set as follows, you get the results shown below:

  • * "C:\Tools\HijackThis.exe" /uninstall causes RC to show the key and all its subkeys as errors (the path does not exist on my system)


    * C:\Program Files\HijackThis\HijackThis.exe /uninstall does not cause RC to show them as errors


    * "C:\Program Files\HijackThis\HijackThis.exe" /uninstall does not cause RC to show them as errors

Therefore, more likely than not, C:\Tools\HijackThis.exe does not exist on Nick555's system … ?

= = = = = = = = = = = = = = = = = = = = = =

During my checking this, a very, very minor RC bug became evident -- if, without closing the results or scan report windows, you do multiple rescans, then the counts shown in the scan report are the sum of the counts from all the scans.

7 days later

Sorry for the delay in my reply. This forum has been unavailable to me for a few days.


I do indeed have HijackThis located in my c:\tools directory. However, the filename is actually HijackThis_v2.exe.


I will uninstall HiJackThis, download the latest version & re-install.

As I expected, HijackThis v2.0 would not uninstall, so I used JV16 to clean. I downloaded & installed HijackThis v2.0.2, ran JV16 again & everything was fine. It appears to have been a problem with the HijackThis installation, thanks for your help!

The TrendMicro V2.0 was a beta and there was a bug in the new uninstaller. :
