How To Remove BestCleaner Unwanted Adware Program

BestCleaner is an adware disguised as a computer optimization tool. However, its main purpose is to hijack your main browsers and display unwanted advertisements. This is why it hasbeen classified as a potentially unwanted program and is detected by most antivirus software.

The program is not as aggressive and dangerous as some other adware. However, its behavior is considered unethical. It does not really help optimizing your machine and only slows it down by hijacking your browsers and displaying its own advertisements. It modifies several places of your system and launches itself. Finally, BestCleaner changes your browsing experience by silently replacing the content of various websites and redirecting to suspicious links.

What is BestCleaner adware?

As mentioned above, this adware is not very dangerous to your computer. It mainly focuses on earning advertisement revenue from displaying advertisements on hijacked browsers. However, it is considered unwanted program as it does not improve the performance of your computer. Instead, it slows the computer down by changing the content of visited webpages and leaving many components in your system in order to facilitate this strategy.

Some of the advertisements are displayed through redirects using http://wizzcaster.com/redirect/. Others appear as popups or are incorporated in the website content instead of original advertisements. The program usually redirects to surveys, other fake PC optimization tools and various full-page advertisements.

This deceptive program has several methods of distribution. Firstly, since it pretends to be a useful application some users might install it themselves. However, a more common method is to bundle BestCleaner with other software and install it together. Many users quickly skip through installation steps and leave the default options selected meaning that BestCleaner and other similar programs can get installed silently in the background.

Remove this adware as soon as possible in order to restore a normal browsing experience. Having BestCleaner on your computer slows down the system. It might also lead to further infections due to unwanted redirects and suspicious advertisements. We recommend using the automatic tool provided at the top of this page. However, if you feel confident editing important Windows system files and settings you can follow our manual removal guide. Have in mind that while you can manually remove the threat and the symptoms your computer still needs to be protected so the problem does not reoccur in the future.

Here are some screenshots of the adware:

NB: Make sure you are comfortable with editing important Windows settings. In order to not only remove the symptoms but also any possible leftovers of the malware we recommend using the automatic tool provided above.

Step 1:

Uninstall BestCleaner.

Start by opening the Programs and Features window using the following method:

Hold Windows () key and click R key while holding.

Enter the following in the field:

appwiz.cpl

Click OK.

You might have to wait a bit before the list of all programs is loaded as it displays a list of all programs installed on your PC.

Look for the following program:

best cleaner
wemonetize

Click Find Next.

Delete any registry entries associated with the virus.

Repeat the search until all entries are cleaned.

Make sure you delete only malicious entries as Windows registry is full of important information and deleting a critical entry might result in damaged operating system!

Step 3:

Delete the following folders:

C:\ProgramData\BestCleaner
C:\Users\YOUR_USER\AppData\Roaming\BestCleaner
C:\Program Files (x86)\BestCleaner
C:\Program Files\BestCleaner

Step 4:

Delete the shortcuts for all browsers on your computer as they have been changed by the adware.

C:\Users\%username\AppData\Local\Packages\Microsoft.MicrosoftEdge_8wekyb3d8bbwe

Clear all contents of the folder. Click CTRL + A to select everything and delete the contents.

After removing the virus

When you have finished removing the virus and reverting your browser settings make sure to protect your computer by installing a good antivirus suite that would identify the threats online and in programs you have downloaded. Also, if you are installing a new software, make sure it has nothing bundled in it by following the install wizard as well as searching for user reviews online.
