PrivacyAssistant is a browser extension developed by SearchAssistant.net. These extensions allegedly offer users a safer way to browse the internet and some other tools to customize the home page with background wallpapers and one-click links that can be added. While all this may sound appealing, PrivacyAssistant also monitors your browser activity, search quarries, clicks, visits, and possibly personal information.
This extension changes your default home page to SearchAssistant.com and rerouting all searches through its search portal, displaying sponsored links instead of your typical search results. While active you may see unwanted ads and even pop-up ads appearing while browsing the internet.
Several anti-virus programs have classified this extension as a Browser Hijacker, and are, therefore, for security reasons, not recommended to keep on your computer.
About Browser Hijackers
Browser hijacking is amongst the web’s constant risks that target internet browsers. It’s a kind of malicious software that alters your internet browser’s configuration settings and redirects you to websites or pages that you had no intention of checking out. They are created to disrupt browser functions for many different reasons. Usually, hijackers will force hits to internet sites of their choice either to increase traffic producing higher advertisement earnings, or to gain a commission for each and every user visiting there. Most people believe that these kinds of websites are legitimate and harmless but that is not the case. Almost every browser hijacker poses an existent threat to your online safety and it’s important to categorize them under privacy dangers. When the program attacks your PC, it starts to mess things up a whole that slows your computer down to a crawl. In the worst-case scenario, you might be forced to deal with serious malware threats as well.
How one can recognize a browser hijack
There are numerous symptoms that point to a browser hijacking: your browser’s home page is suddenly different; you get re-directed to sites you never meant to visit; the default web engine has been changed and your web browser security settings have been lowered without your knowledge; find new toolbars that you simply did not add; you might find many pop-up ads on your computer screen; your web browser starts running slowly or displays frequent errors; you have prohibited entry to certain web pages, for example, the website of an antivirus software developer like SafeBytes.
So how exactly does a browser hijacker infect a PC
Browser hijackers may use drive-by downloads or file-sharing websites or perhaps an email attachment in order to reach a targeted computer system. They can also originate from any BHO, extension, toolbar, add-on, or plug-in with malicious intent. Other times you might have unintentionally accepted a browser hijacker as part of a software program bundle (generally freeware or shareware). A good example of some popular browser hijackers includes Conduit, Anyprotect, Babylon, DefaultTab, SweetPage, Delta Search, and RocketTab, however, the names are constantly changing.
Browser hijacking can lead to serious privacy problems and even identity theft, disrupt your browsing experience by taking control over outgoing traffic, considerably slows down your personal computer by consuming lots of system resources, and result in system instability at the same time.
How to repair a browser hijack
Some hijackers can be removed by uninstalling the free software they were included with or by deleting any extension you’ve recently added to your browser. But, the majority of hijackers are extremely tenacious and require specialized applications to eradicate them. Furthermore, manual removal requires you to execute many time-consuming and tricky procedures which are hard to carry out for inexperienced computer users.
How To Get Rid Of Virus That Is Preventing Antivirus Installation?
Viruses can cause a great deal of damage to your computer system. Some malware sits in between the computer and your net connection and blocks some or all sites that you really want to visit. It will also prevent you from installing anything on your computer, especially anti-malware software. So what to do if malicious software keeps you from downloading or installing Safebytes Anti-Malware? Although this sort of problem can be difficult to circumvent, there are some actions you can take.
Make use of Safe Mode to resolve the problem
In Safe Mode, you can actually change Windows settings, un-install or install some software, and eliminate hard-to-delete malware. In case the malware is set to load immediately when PC boots, switching into this mode may well prevent it from doing so. To enter into Safe Mode or Safe Mode with Networking, press F8 while the system is starting up or run MSCONFIG and look for the “Safe Boot” options in the “Boot” tab. Once you’re in safe mode, you can try to install your anti-malware program without the hindrance of the malicious software. Following installation, run the malware scanner to remove most standard infections.
Switch over to some other web browser
Some malware mainly targets specific browsers. If this is your situation, use another internet browser as it can circumvent the malware. In the event you suspect that your Internet Explorer has been hijacked by a computer virus or otherwise compromised by cybercriminals, the best approach is to switch over to a different internet browser like Mozilla Firefox, Google Chrome, or Apple Safari to download your favorite computer security program – Safebytes Anti-Malware.

As in most usual online scams, everything starts with a strange email containing threats and other poorly written and composed speech. At the end of the given email, there would be a link claiming that you, of course, need to read it and follow instructions about the threat, if you click the link it will open a web page where you will have an innocent-looking PDF file with more information about the threat itself.
If you click on a seemingly innocent PDF file it will summon Windows 10's AppInstaller.exe tool, kickstarting a download-and-run process that'll put you in a bad place very quickly. From there, you'll have to deal with the dangers of malware BazarBackdoor, including data and credential theft.
This kind of scam is nothing new but the interesting thing here is that it uses App installer and by clicking on a link you are opening and giving permission for a malicious crook to use it. So, stay safe and do not click on any links from unknown emails no matter what.
