This page aims to help you remove Ads by Serpens. These removal instructions work for Chrome, Firefox, Internet Explorer and Safari, as well as every version of Windows.

Ads by Serpens was released in one of the latest waves of Adware threats. It is easily recognizable by the large amount of pop-ups and banners containing Ads that it will inject into the internet browsers of infected computers. Cyber-ware security experts agree that this type of malicious application is not among the most dangerous ones, but nevertheless it should not be underestimated. Remove it as soon as you can (probably by the time you are done reading this article). If you have downloaded and installed any programs, toolbars or other software via a link or site provided by any Ad from the virus you should immediately uninstall it as well. We’ll explain why below.

The main danger from applications such as Ads by Serpens does not come from themselves. Rather they are dangerous because they can help other vicious types of malware to get inside your computer. The main function of Adware is to generate money for whoever created it by showing Ads on the affected computers. The creator then gets a modest payment for each click on an Ad or a larger one if anything is purchased from such an Ad – largely as an affiliate. The problem is that developers of Adware rarely execute any kind of control over the quality of the Ads displayed. Because of this they are very often used to spread viruses, trojan horses, other Adware and even spy programs. Because of this all Ads from Ads by Serpens should be ignore and any software downloads immediately aborted.

Methods of spreading used by Ads by Serpens

There are a couple of known tricks used to distribute malicious applications such as Ads by Serpens. By far and large the most popular ones are:

  1. As email attachments. These can be made to look convincing, especially if the sender of the spam did not use Google Translate to translate the scam message from Chinese.  The most successful ones pose as work-related Emails and files. They’ll always end in .exe and that’s the best indication to look if you are unsure. Invoice.exe is most definitely a virus.
  2. As part of a software bundle. A software bundle is essentially a program installer that contains more then one program inside of it. Using the Default installation option will install the main program and all extras as allowed “by default”. Rarely the extras contain anything useful – most of the time things like Ads by Serpens are lurking inside. To avoid getting infected like this always select the Advanced installation option for any installer and then remove the checks from all boxes that will install unwanted additional software on your PC.
  3. Fake Ads, torrents and online storage sites. These are a breeding ground for all kinds of viruses and getting an Adware like Ads by Serpens should be considered lucky. The Ads on these sites almost always lead to viruses and bloatware. They also usually contain multiple download buttons of which only one is real. If you click on the fake one you’ll be prompted to download some file that shares a name with the file you searched for. Inside, however, will be hidden a virus.

It’s also worth nothing that all internet browsers are equally vulnerable to Ads by Serpens once it is installed on your computer. The instructions for its removal from Firefox, Chrome and IE differ, but we’ll go into this detail in the removal guide itself that starts below.

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.


The final part of the guide is up next and it is a bit more trickier then the rest.

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.


Take a look at the following things:

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

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/uninstall the registries manually:

  • HKEY_CURRENT_USER—-Software—–Random Directory. It could be any one of them – ask us if you can’t discern which ones are malicious, but bear in mind they are always different.
    HKEY_CURRENT_USER—-Software—Microsoft—-Windows—CurrentVersion—Run– Random
    HKEY_CURRENT_USER—-Software—Microsoft—Internet Explorer—-Main—- Random

  • Please suggest the best malware removing tool that will automatically remove all the irritating pop-ups causing virus/adware…I tried Adwcleaner, Yet Another Cleaner which didn’t help…Eagerly waiting for your earliest reply.Thanks

    • Honestly, whenever someone asks me something like this, I just want to help you and I cringe a little bit because I want to do justice to the trust you put in us. Here’s what I see with the programs you mentioned and what I’d recommend:
      I’d absolutely avoid using Yet Another Cleaner, as it has been reported to behave in a very unprofessional way. This is one of the worse choices you can make to protect your system.

      Adwcleaner is a good program generally, although the people who update it are not as fast to respond to threats. But it’s free.

      If you click on one of our advertisements you can download SpyHunter. Spyhunter’s scanner is free, I suggest you use it. If it’s not picking up the virus, nothing else will. If it picks up the virus (and last I checked it does) you have the option of buying SpyHunter to remove the virus and you’ll have protection for the next 6 months, or you can just use the scanner to find the infected files and I’ll try myself to help you remove them manually. The scanner will just point where they are.
      Generally SpyHunter is the best choice to remove any adware/viruses.
