Ads by Ad by Currency is a type of invasive program that has recently been spotted to rapidly infect computers over the internet. It does that with the help of various techniques, which we will help identify for the purpose of future recognition and prevention. On nearly all occasions it comes bundled with the installer of other software or through another type of infected executable file.

  • Installers for certain software will often try to install other programs beside the main application. Unless the installer is really malicious there is an easy way to not fall in this pit – you simply need to always select advanced installation in the install options. Going advanced will take just a couple of more clicks, but in the meantime will give you detailed information about what is getting installed. You should deny access for any additional applications you see there.
  • Getting infected via dangerous software is only possible if you install unsafe .exe files. An unsafe .exe file is basically any file that is not obtained from the official developer’s site or approved mirrors. Forums, emails, torrents and online storage sites all fall in this category.

Whatever the case of infection may be you need to remove Ad by Currency fast. 

Don’t click on the Ads created bt Ad by Currency, don’t download and install anything

Ad by Currency is not considered a very dangerous virus because the Ads themselves pose no direct threat to your PC. Unfortunately they are not totally harmless either. If you make the mistake of clicking on them – or even worse, download some program they offer you this could mean a lot of trouble.

On all occasions Ad by Currency will either try to install a virus on your machine or try to run some hoax on you involving bloatware and non-existing problems on your computer (who are just very creative Ads and not real problems) Anti-virus, anti-malware, scanners, registry fixers, PC optimize software and the list goes on and on. Ad by Currency may try to bombard you with all kinds of scary messages prompting the download of a (fake) anti-virus software or (fake) PC utility programs. If you believe the messages are not fake (and not created by Ad by Currency) then you can try to download the above mentioned software, but look for it via google and grab the necessary executable from the official site.

2: Remove Ad by Currency from Chrome, Firefox, Internet Explorer and Safari.

With Safe Mode enabled it is time to target Ad by Currency for termination. We’ll begin by cleaning your internet browsers. You need to clean every single one of those – even browsers that you don’t regularly use, but which still remain installed on your computer. To do that run Step 2 and Step 3 for every browser.

Be careful as Ad by Currency may pop a message when you try to delete it. It can contain convoluted wording (no meaning yes) or it could try to download another virus from the family on your machine. Read the text carefully and pick the correct response.

Go to STEP 3.

firefox-512  For Mozilla Firefox Users:

Open Firefoxclick on mozilla menu (top right) ——-> Add-onsHit Extensions next.

Ad by Currency  should be somewhere around here –  Remove it.

Go to STEP 3.

chrome-logo-transparent-background For Google Chrome Users

 Start Chrome, click chrome menu icon —–>More Tools —–> Extensions. There,  find the virus and  select  chrome-trash-icon(Remove).

 Click chrome menu icon again, and proceed to Settings —> Search, the fourth tab, select Manage Search Engines.  Remove anything but the search engines you normally use.

Go to STEP 3.

safari For Safari Users:

Open Safari, and click Safari —–>Preferences —–> Extensions—–>Uninstall the malware.

Go to STEP 3.


Right click on the browser’s shortcut, then click Properties.

NOTE: We are showing Google Chrome, but the method is the same for all browsers.


Once you’ve reached Properties —–> Shortcut (on the band at the top), then in the Target type field, REMOVE EVERYTHING AFTER .exe.

Continue with STEP 4.


Hold the Windows Key and R together. Write appwiz.cpl in the new field, then click OK.


You are now in the Control Panel. Search around for Ad by Currency and anything else suspicious-looking. Uninstall it/them. Also, be extremely careful. Viruses often spend one last ditch effort to trick you into installing more of their kind. If you see a screen like this when you click Uninstallchoose NO:


Hold the Windows Key and R againbut this time copy + paste the following and click OK:

notepad %windir%/system32/Drivers/etc/hosts

A .txt file will open – don’t touch anything there. If you are hacked and someone has access to your PC, there will be a bunch of other IPs connected to you at the bottom. This is what a hosts file looks like:

hosts_opt (1)

If there are a bunch of strange IPs connecting to you below “Localhost” you may be hacked, and it’s best to ask us in the comments for directions.

Go to STEP 5.


Open the Task Manager by right clicking on the Taskbar and choosing Start Task Manager.


Once it opens, choose the Processes Tab. Look at all of the processes in front of you and try to determine which ones are a virus. Google them or ask us in the comments and we will provide the best assistance we can.


This step is perhaps the most important, but also the most difficult and potentially dangerous. It involved deletion of files that could be easily confused with important system files, so you need to double check everything before deleting it. Getting this wrong can damage your Windows installation or other important programs significantly! If you are not feeling comfortable, you can instead try the safe approach – download a professional anti-malware program – look for our recommendation below. It will cost you a few bucks, but you’ll get long-term protection and you will also be able to scan your computer for other viruses that may be hiding invisible and waiting to strike. Ransomware and different Rootkits are notoriously dangerous and do not reveal themselves until it is too late to do anything about them.


Right click on each of the virus processes separately and select Open File Location. Also, End the process after you open the folder. Just to make sure we don’t delete any programs you mistakenly took for a virus, copy the folders somewhere, then delete the directories you were sent to.

Move on to STEP 6.


Take a look at the following things:

Type msconfig in the search field and hit enter: you will be transported to a new window. 


Go in the Startup tab and Uncheck anything that has “Unknown” as Manufacturer.

Type Regedit in the windows search field and press Enter.

Once inside, press CTRL and F together and type the virus’s Name. Right click and delete any entries you find with a similar name. If you can’t find them this way, look in these directories, and delete the registries manually:

  • HKEY_CURRENT_USER—-Software—–Random numbers
    HKEY_CURRENT_USER—-Software—Microsoft—-Windows—CurrentVersion—Run– Random
    HKEY_CURRENT_USER—-Software—Microsoft—Internet Explorer—-Main—- Random
