Browser Assistant – PUP that abuses JavaScript to inject advertisements into Chrome or Firefox browsers

Browser Assistant virusBrowser Assistant virus is infecting only Windows devices

Browser Assistant is flagged by some anti-malware software as a Trojan by the heuristic detection name -Trojan.BrowserAssistant.PS. This piece of software is extremely dangerous as it alters system files and settings to establish persistence. Moreover, it is capable of spreading adware, browser hijackers, other potentially unwanted programs (PUPs), or even act as a bridge for malware infections.

Browser Assistant virus is much more than a regular PUP. It can install other dangerous programs without your knowledge or permission. It shows deceptive ads in various forms, including pop-ups, banners, in-text hyperlinks, etc. And it can cause redirects forcing you to visit a site of its choice on demand.

Affiliated sites of this type of software are usually hazardous portals with explicit or even malicious content that will try to steal your private information, infect your devices with severe viruses, and so on. This article contains instructions on how to remove this PUP bundler and how to restore your system to a pre-contamination phase.

According to researchers, Browser Assistant is installed on devices from software bundles. But that doesn't mean that that's the only way this PUP can be distributed. Other viable options include promotional offers online, deceptive ads, fake Flash Player updates/installers, and alike.

When Browser Assistant adware finds its way into your machine, you might spot some irregularities, such as more than usual ads on your frequently visited pages, sudden redirects to questionable sites, performance issues, various system irregularities, such as BSoDs, freezing, severe lag, etc.

Browser Assistant ads are originating from a different source than the sites you're visiting. That's what makes them dangerous. When such ads are clicked, you might get redirected to sites with other PUPs, push notification viruses, malware, gambling, porn, various tech scams, and other hazardous portals.

Furthermore, Browser Assistant virus might be able to collect non-personal (device and browser details, IP addresses, used apps, visited sites, etc.) and personal (credit card details, phone numbers, emails) information. Gathered data is usually used to make ads more attractive to you. If this data fell into the wrong hands, you could become a victim of a cybercrime.

Browser Assistant bundlerBrowser Assistant bundler is identified as a malicious application by more than one AV engine

Thus, you have to perform a full system scan with a proper security tool ASAP to remove Browser Assistant. If you don't have one, you should download free anti-malware software such as SpyHunter 5Combo Cleaner or Malwarebytes. Either of those AV tools is capable of identifying severe malware as well as PUPs and eliminating them automatically.

As stated before, this adware bundler causes havoc on system files and settings to establish persistence, i.e., be harder to detect. These modifications might result in unstable working conditions. Therefore, we highly recommend resolving any system-related issues with the time-proven ReimageIntego system repair tool so you could enjoy your device anew.

Pay attention when installing new software to avoid PUPs

Potentially unwanted program developers use many different techniques to spread their creations. Our research suggests that one of the most popular PUP distribution methods is via software bundles. These packs containing installers for multiple apps are usually downloaded from third-party software vendors.

But lately, legitimate software developers have decided to increase their profits by adding PUPs to their software. Thus you have to be cautious when installing any new software. The main thing is not to rush. When installing new programs, always choose the Custom or Advanced more, instead of the Quick, Recommended, Standard ones.

Browser AssistantBrowser Assistant is a PUP that injects JavaScript into browsers which allows it to show affiliated, malicious content

Then go step-by-step, deselecting all apps from the installation that seem at least a bit suspicious, or are unknown, unwanted, or that you didn't even know that would be installed in the first place. Get only the app you wanted initially, and remember to do this each time when installing new software.

Remove Browser Assistant virus completely with simple two steps

Browser Assistant virus can cause havoc on your device and put your PC security at risk. It can install various potentially unwanted programs (adware, browser hijackers, etc.) or even severe malware, record your private data, show deceptive ads, and cause redirects to malicious sites.

You have to remove Browser Assistant immediately. The best way to do it is to entrust this task to a reliable anti-malware tool. Launch it, update its virus signatures, and perform a full system scan. When it's done, comply with the security tool's recommendations on how to proceed further.

Once installed the app creates startup items, injects registry entries and distributes its other files all over the system. If these changes are left unattended, your device might remain compromised. Thus, after Browser Assistant bundler removal, use a proper system repair tool to fix any and all system inconsistencies.

How to prevent from getting adware

Securely connect to your website wherever you are

Sometimes you may need to log in to a content management system or server more often, especially if you are actively working on a blog, website, or different project that needs constant maintenance or that requires frequent content updates or other changes. Avoiding this problem can be easy if you choose a dedicated/fixed IP address. It's a static IP address that only belongs to a specific device and does not change when you are in different locations. 

VPN service providers such as Private Internet Access can help you with these settings. This tool can help you control your online reputation and successfully manage your projects wherever you are. It is important to prevent different IP addresses from connecting to your website. With a dedicated/fixed IP address, VPN service, and secure access to a content management system, your project will remain secure.

Recover files damaged by a dangerous malware attack

Despite the fact that there are various circumstances that can cause data to be lost on a system, including accidental deletion, the most common reason people lose photos, documents, videos, and other important data is the infection of malware.

Some malicious programs can delete files and prevent the software from running smoothly. However, there is a greater threat from the dangerous viruses that can encrypt documents, system files, and images. Ransomware-type viruses focus on encrypting data and restricting users’ access to files, so you can permanently lose personal data when you download such a virus to your computer.

The ability to unlock encrypted files is very limited, but some programs have a data recovery feature. In some cases, the Data Recovery Pro program can help recover at least some of the data that has been locked by a virus or other cyber infection.
