How to remove DownloadTerms 1.0?


This began with the search here infection. After removing this and the other related culprits, DownloadTerms 1.0 installed itself. This happened on 5/8 which is relevant because this little bugger seems to have changed in order to subvert successful removal tactics. There is no remove button in addons and I have run mbam and norton with no success. The only place I could find this app was in my app data folder, however there is no unist.exe. I deleted it from there, but I have no idea what, if any, effect this will have. I want this gone. I am guessing I could manually remove from reg, but I have no idea, and searches turned up zip, what the reg entry is. Is this thing even listed as malware in virus definitions?

Thanx for the time man, but the op specifically says that these methods do not work.

Have you tried the malware cleaners to try to clean up remnants left behind on your system? The cleaners each may find different items on your system that others do not.

Have you tried posting on the malware removal forums for assistance from malware removal experts?

Okay, so I searched the registry and nothing turned up. The DownloadTerms 1.0 extension is still listed in extensions, but when I enable, it does not work. Does this mean its gone, and some piece is just stuck listing it in my extensions? Did a reg clean, and YES I have used various malware and antivirus scans, as stated in op.

You indicated in your original question that the only trace you found was "in my app data folder, however there is no unist.exe. I deleted it from there".

  • The Firefox extension would not have been added from there unless some very unusual malware installed it then deleted itself.
  • If there is nothing in your Windows Control Panel > Programs/Features (or Add/Remove Programs) related to the item, you can try removing the extension from your Firefox profile folder. It will be found in a folder named "extensions".
  • The extension may be identified by its GUID instead of the extensions name. You can use this add-on to obtain the GUID if necessary - https://addons.mozilla.org/en-US/firefox/addon/extension-list-dumper/
    • After installing the add-on and restarting Firefox you will find a new button on the Add-ons Manager display, "Dump List".
    • You can change the items displayed for each extension, but you need ID checked to see the GUID.
    • Perform the removal with Firefox closed.
  • See - https://support.mozilla.org/en-US/kb/profiles-where-firefox-stores-user-data#w_how-do-i-find-my-profile

NOTE: Removing it in the manner above may not remove everything associated with "Download Terms 1.0". In addition, if the extension is being added by a program installed on your system, it may reappear in Firefox Add-on Manager at any time.

To be certain that your system is clean including the registry, I strongly urge you to seek assistance from one of the forums specializing in malware removal listed in the article posted in one of my prior replies in this thread.
