Ultra Adware Killer

Ultra Adware Killer overview

Ultra Adware Killer is a simple but powerful adware remover for Windows, which has the ability of detecting and removing adware for all the users in a system. This can save you lots of time logging in to other user accounts and performing the scan again.

Ultra Adware Killer removes browser toolbars, ad-ons, plugins, unwanted search providers and hijacked home pages, and also potentially unwanted programs (PUP's). It also allows to optionally reset the browsers configuration, allowing them to run as smoothly as when they were installed. Click here for more info. 

Ultra Adware Killer was built to be fast, simple and effective. Usually you just need to pres the Start scan button, wait until the scan ends, and then remove the items found. Normally the whole operation takes only a few minutes. For more information, please see our help content.

Scanning for adware

To start a scan, press the Start scan button. This button will then become Stop scan. You can press it again anytime during the scan, to cancel the scan. The whole scan usually only takes a few seconds.

If you want to scan only the current user, uncheck Scan all users, before starting the scan. The SYSTEM account will always be scanned, though.

The progress bar just below the Start scan button will tell you the scan's progress, and a text label below the progress bar will tell you which section is currently being scanned.

While the scan is being performed, you can have a look the the items already found. Double-clicking an item automatically takes you to its location in the registry. You can also jump to the item's location in the file system, when available, by right-clicking the item's line and selecting Open file location. This allows you to have a better insight of the item, and decide whether you want to remove it or not.

Tip: To save time, while the scan is being processed, uncheck any items you don't want to remove, or whitelist items you don't want Ultra Adware killer to display in future scans. More info on the whitelist below.

You can quickly check/unckeck all items in the list: right-click the list to open it's context menu, and then select Check all, or Check none, respectively. The context menu also has a Open registry location menu item which will perform the same action as double-clicking the list item, as mentioned above.

When the scan is complete you will be presented with a message box telling you how many items were found, and you can access the scan's log by pressing the Menu button, and then selecting the View scan log menu item.

As mentioned above, you can whitelist any of the items in the list, after a scan is complete, or even during the scan. Just select the desired list (Programs, Internet Explorer, Chrome or Firefox), then right-click the item you want to whitelist and finally select Whitelist this item. Whitelisted items will not be detected again and are immediately removed from the list.

To manage the Ultra Adware Killer's whitelist, press the Menu button, and select Whitelist manager. You will be presented with a dialog box similar to the one in the picture below.

Ultra adware killer whitelist

The list shows the whitelisted items. Thick the checkbox next to the items you want to remove from the list, press Delete checked and confirm. This removes the item(s) form the whitelist, meaning they will be detected again, when present.

You can easily export and import the whitelist to/from an external file. This will be particularly useful to make baclup copies of the whitelist, or to transfer it to a different computer. To import the whitelist from a file, press Import list and select the INI file the list was previously exported to. To export the list, press Export list and select the INI file path and name you wish to export to.

When you are done using this feature, press Close / Cancel to close this dialog box.

Selecting the items to remove

Before removing the items found, you can set the check state of the items you want to remove, or ignore. Items will only be removed/fixed if the corresponding check box is ticked. Ultra Adware Killer 2.0+ makes this process really easy, by providing only the names of the programs to remove, and by spliting the browser repair options into several groups.

Ultra adware killer automatically checks most of the items during the scan. However, some items may not be checked by defaut, depending on their nature. You can check the desired items in just a few seconds.

Browser reset options are usualy unchecked. You can manually check those options if removing the other items did not restore the desired browser's functionality. Try removing the items selected by default once, if that does not fix your problem, check all the options and try again. That should get your browser working properly.

After selecting the desired items to remove or fix, you are ready to begin the removal process.

Deleting/fixing the selected items

Once the adware scan is complete, and you selected the desired items to remove, press the Cleanup button to start removing or fixing the selected items.

Some of the selected items will be removed, but others of them will be fixed instead. For instance, hijacked browser shortcuts will be fixed, programs are always removed. Ultra Adware Killer knows which items it must fix or delete, no action is required from your side.

If Create restore point is checked, a restore point is created before the removal process.

File system objects that Ultra Adware Killer does not manage to remove immediately are scheduled for removal on reboot. In this case, Ultra Adware Killer will ask you if you want to reboot immediately. You can choose No, if you want to manually reboot later.

Once the removal process is complete, you can read the removal log by pressing the Menu button and then selecting the View removal log menu item.

Application logs

You can access the scan and removal logs by pressing the Menu button and then selecting View scan log, or View removal log. Obviously, the scan log is only available after you complete a scan, and the removal log is only available after you remove the items found.

If you want to access logs of previous scans or removals, select Open logs folder, instead, and manually open the desired log. Application log names are timestamp based, meaning the higher the number in the log's file name, the more recently the log was created. The Windows file explorer should automatically sort them in the correct order, from the oldest to the newest.

The logs are very self-explanatory. The scan log contains a header with some useful system information, such as the Windows version, installed browsers' versions, and the name of the user that started Ultra Adware Killer. This information may help you to detect an outdated browser, or a missing service pack.

Items found (in the scan log) or items removed (in the removal log) are ordered by the corresponding section: Programs, Internet Explorer, Chrome and Firefox.

Registry related items are prefixed in a special way, that makes it easier to identify the corresponding registry key, and also shortens the line's text:

@UserName: A registry key located in the UserName's registry portion (hive).
HKLM64: A registry key located in the 64 bit portion of the HKEY_LOCAL_MACHINE key, in 64 bits Windows versions.
HKLM32: A registry key located in the 32 bit portion of the HKEY_LOCAL_MACHINE key, in 64 bits Windows versions.
HKCR64: A registry key located in the 64 bit portion of the HKEY_CLASSES_ROOT key, in 64 bits Windows versions.
HKCR32: A registry key located in the 32 bit portion of the HKEY_CLASSES_ROOT key, in 64 bits Windows versions.

For 32 bits Windows versions, HKLM and HKCR are used instead. Specific value names or data parts to remove are specified in the lines below the key's line.

In the scan log, all reported items contain an extra line telling the item's check state when the scan completed.

Removal logs thell the result of the removal/repair operation for each item.
