We are pretty sure you have been affected by Ad Network Performance Virus in one way or another if you are reading this article. If you are looking for general information about this program then continue reading. If you are looking for a way to remove it from your system then no worries – we will provide this for you as well.

Adnetworkperformance display virus

First of all you should know what you are dealing with and that is most likely a virus of the Adware class. Typically adnetworkperformance display virus will provide a never-ending stream of Ads for you to deal with. Whether in the form of pop-up windows or banners one thing is certain – there will be no way for you to completely ignore them. The displayed advertisements can actually promote a number of things but most likely they will offer you something that might be of some interest to you. In order to achieve this effect Ad Network Performance Virus targets your online browsing data – history, cache, cookies, related searches. As you can imagine this is quite dangerous for the affected user and might have some very serious implications.

Other negative effects attributed to Ad Network Performance Virus

At the very least you are going to experience severe computer slowdown. That is mainly due to the fact that any time you load a web page an ad is also going to be loaded so it will take double the amount of processing power to load it successfully. This is quite taxing for any system and will certainly take its toll down the road if not taken care of. But especially for older systems it might lead to a complete freezing of the OS or even a blue screen of death.

Another aspect for you to consider is that these advertisements if interacted with will very often lead to fake websites that are looking like the real deal but are in fact not. Even a small difference in the URL address is a clear sign that you have been redirected to a dangerous place. This can be quite tricky to notice but you should be on the lookout at least until you remove Ad Network Performance Virus from your computer.

Another important tip to remember – never install anything prompted by this malware.

    Hi again,

    If you still get the Ads even on a fresh install and the guide didn’t help then maybe the Ads are created by the blog itself. Contact the hosting company for that, especially if this is a free blogging service.

    Alternatively you can download and install the Ad Block plug-in for Chrome and use it to block the Ads.

      HI John,

      Can you try resetting your google profile? You can do so by going to the options menu, look for the accounts section. Create a new profile, then delete the old one.

      Did it help?

  • Hi,

    I follow all the instructions, yet it still doesn’t remove. I also done resetting my google profile. Can you help me with this?

    • HowToRemove.Guide Team

      Hi Donna,

      Can you open your network adapter, click properties, select IP4 protocol and click properties again.

      Do you see any numbers in the DNS field?

  • HowToRemove.Guide Team

    Okay, press Win+R, type “msconfig” without the commas. Look at the startup section. Anything suspicious there?

  • HowToRemove.Guide Team

    Hi Quan,

    Can you press Win+R and type msconfig. Look up the startup tab – anything suspicious there?

  • HowToRemove.Guide Team

    Okay Donna, try downloading SpyHunter from one of our banners and run a system scan – that’s free. This should give us a clue where the virus is hiding and you can delete it manually if you don’t want to pay for the program.

    • Hi, Thanks for this I just got a hint in some of my program that I installed. I just uninstalled it and there is no dns unblocker and adnetwork performance popping out on my browsers anymore thank you very much!

      • HowToRemove.Guide Team

        Hi Donna, glad you were able to solve this!

  • HowToRemove.Guide Team

    Hi Shae, if you are absolutely sure you did everything correctly its possible we are dealing with a new variation of the virus. What you can do is download SpyHunter from one of our banners and run a system scan. This is free, so you don’t need to pay anything for the program. If SpyHunter locates the virus you can just go the the folder it points out to and delete it manually yourself (or pay a subscription and let the program delete it for you).

  • HowToRemove.Guide Team

    Hi Shae, do you remember if Spyhunter found and deleted Ad Network Performance specifically? Its possible that the virus is gone, but the adjustments it has made to your browser remain. You’ll have to reset your browser manually. Do you use Chrome, Firefox or IE?

  • HowToRemove.Guide Team

    Hi Leah, sorry for the delay.

    If you are sure the guide yields nothing can you try to download SpyHunter and run a system scan. You don’t need to pay anything to scan. Can you tell me if the program finds anything?

  • HowToRemove.Guide Team

    I’m sorry for the slow reply. Were you able to the resolve the situation on your own or do you still need help?

  • Danielle

    Hi, I did step 1 (pressed shift, and chose save mode with networkoptions) But now I do not even have internet explorer of any other browser on my laptop. Can you help me?

    • HowToRemove.Guide Team

      Did you uninstall all of your browsers? Download an installer from another device, load it on an USB and re-install it on your laptop.

  • HowToRemove.Guide Team
