Have you seen something like Browser Assistant s10.dll on your PC? Is it malware? Should you remove it? This article is going to explain all of the mysteries.

Antivirus and anti-malware programs tend to give many false-positive alerts. So, some people may ignore many of them. If your security tool has recently alerted you about Browser Assistant.exe or an S10.dll file, you may want to know more about it.

What is Browser Assistant, and do I need it?

The Browser Assistant is a potentially unwanted program (PUP) that you may find on your computer even though you have not installed it. It activates its activities via a browser extension or add-ons and does a lot of harm.

You can find Browser Assistant as a stand-alone program or as an extension or add-on on any other browser.

In recent years, we have seen many antiviruses or antimalware programs giving security alerts if this tool exists on your PC.

Sometimes, you may find that the S10.dll file is using a lot of resources on your PC. Even though S10.dll is a legit file, it still can be malware or trojan, depending on its location and activities. The legit one should not use a lot of resources.

You may observe that the Browser Assistant uses the S10.dll file to do a lot of things that seem suspicious. In some cases, another file named Updater 10.dll can be related to the problem we are discussing.

Is browser assistant malicious?

Yes. It is malicious. Some security tools have tagged it as an adware trojan, which is detected as Trojan.BrowserAssistant.PS. 

Whatever it is, this Browser Assistant allows cyber criminals or any virus to get access to your devices and make unnecessary changes, and do a lot of unwanted things.

There is no doubt that this malicious PUP is not useful at all. On the other hand, it can cause severe damage to your privacy and security. Thus, you do not need it. You must remove this threat when you first see it on your computer.

In fact, you do not need anything to manage your browser. Microsoft, Google, Mozilla, Opera, etc., already have implemented powerful features, which are enough.

Keep in mind that some browser extensions with similar names for Chrome, Firefox, Opera, and Microsoft Edge are legit. So, it will be a bit tricky to cure the actual problem. But, don’t worry, we will show you the right way.

Expert Tip: Some PC issues are hard to tackle, especially when it comes to corrupted repositories or missing Windows files. If you are having troubles fixing an error, your system may be partially broken. We recommend installing Restoro, a tool that will scan your machine and identify what the fault is.
