Remove Browser Assistant - Jan 2021 update
Browser Assistant – adware bundler published by Realistic Media that promotes, downloads, and installs potentially unwanted programs
Browser Assistant is the program related to a particular heuristic detection name Trojan.BrowserAssistant.PS that functions as a vessel to PUPs. It can be considered an installer designed to infect machines without users' knowledge and spread adware, fake installers, or even malware. It gets recognized by AV tools, and such software can remove it, but this is a silent intruder that causes redirects and can come with different programs. It is possible to encounter privacy issues since PUPs like that can track and collect data about your online preferences and habits.
This potentially unwanted program can be considered a Browser Assistant virus because it allows various threat actors to access devices and install their products in those adware bundles. There is no guarantee that pre-packed bundles have only PUPs and nothing malicious. The installer itself adds applications in Programs and Features folder, windows registry, startup folder. The intruder can affect more parts of the system than a typical PUP, so you should consider this program dangerous and take action as soon as possible.

The bundler itself is introduced to the infected machine by a trojan, according to analysis and detections. It may end up installed on the system alongside other programs like spyware, malware, or PUPs initially.
However, the main purpose of the Browser Assistant is to be a tool that spreads other infections and collects personal data for marketing, or in other words, malvertising purposes. Such data tracking functions come with many PUPs, so the infection itself and all the material loaded after that can access, track, and record data about users browsing habits, preferences, and even personal details.[2]
Browser Assistant – related advertisers use such details to make personalized advertisements that later on appear on victims' screens or sell the collected data to third-party companies. Such behavior leads to junk email messages, telephone calls, scammers, and telemarketing campaigns targeting you.
Additional Browser Assistant adware symptoms may include:
- pop-ups, banners, and other types of advertisements;
- browser redirects;
- push notifications or browser pop-ups with suspicious system messages;
- speed and performance issues;
- crashes or freezes of the browser or device.
However, Trojan.BrowserAssistant.PS is associated with BrowserAssistant.exe file that is considered malicious in the first place. It is common that trojans and other more serious malware get hidden on common type files, including executables that often appear running in the background.
Due to the common .exe type, people tend to ignore the file. This is how the program can do whatever it is designed to do. So make sure to remove Browser Assistant as soon as you can and rely on an anti-malware program that can detect, quarantine and delete the potentially unwanted program or even a trojan that distributes this shady bundler. Browser Assistant is the PUP that gets detected as a dangerous application loaded out of nowhere since it is installed without permission. Browser Assistant removal might get difficult due to files planted in Startup folders, Windows registry, and programs installed on the machine. This program may install media players, audio codecs, converters, other software with questionable purposes.

Since Browser Assistant can install any ad-supported PUP and expose you to advertising material, malicious pages, your data is at risk. Redirects-based threats focus on techniques that generate money, so data tracking and personalized commercial content are some of the methods.
However, this means that when Browser Assistant is present on the machine, tags, cookies, pixels, and other tools designed to collect web surfing data get employed. Since you get exposed to other sites where ad-tracking techniques are present and malicious codes may get triggered. Also, experts[3] note that the computer can get damaged by more serious malware than adware or browser hijacker due to content online that is not controlled and can be unsafe.
Try to ignore all the redirects to phishing pages and promotional ads because clicking on such content gets to you malicious pages and makes Browser Assistant more persistent since it has more time on the device. Run a full system scan with anti-malware tools, so all the threats and malicious programs get terminated entirely.
The internet is filled with questionable PUPs and malware
Typically, potentially unwanted programs are downloaded from sites that promote and distribute other applications with questionable purposes. In most cases, these pages also include additional freeware in the bundles, and during the shady installation, software gets installed unnoticed.
Insecure installations load useless applications and make certain downloads when the user is in a hurry and skips through important steps by choosing recommended or Quick options instead of Advanced/Custom installations. If you do this, you can prevent problems by unselecting attachments, media player,s suspicious optimizers, and other files.
Unfortunately, when altered or maliciously infected executable files and trojans end up on the machine, there is little you can do. Such malware mainly spreads via malicious sites and email notifications containing payload droppers. Paying attention to any content online is a crucial thing because when you avoid opening suspicious emails or visiting misleading sites, you can also avoid cyber infections.

Stream videos without limitations, no matter where you are
There are multiple parties that could find out almost anything about you by checking your online activity. While this is highly unlikely, advertisers and tech companies are constantly tracking you online. The first step to privacy should be a secure browser that focuses on tracker reduction to a minimum.
Even if you employ a secure browser, you will not be able to access websites that are restricted due to local government laws or other reasons. In other words, you may not be able to stream Disney+ or US-based Netflix in some countries. To bypass these restrictions, you can employ a powerful Private Internet Access VPN, which provides dedicated servers for torrenting and streaming, not slowing you down in the process.
Data backups are important – recover your lost files
Ransomware is one of the biggest threats to personal data. Once it is executed on a machine, it launches a sophisticated encryption algorithm that locks all your files, although it does not destroy them. The most common misconception is that anti-malware software can return files to their previous states. This is not true, however, and data remains locked after the malicious payload is deleted.
While regular data backups are the only secure method to recover your files after a ransomware attack, tools such as Data Recovery Pro can also be effective and restore at least some of your lost data.
