WebAssistSearch is the intruder categorized as adware due to shady commercial content delivery and questionable symptoms
| Name | WebAssistSearch |
|---|---|
| Type | Adware/ Macro virus |
| Symptoms | The application appears running in the background or placed in some of the folders, so the person is frustrated when the app is not easily detectable. It pushes commercial content, other apps, system tools |
| Distribution | Freeware installations when you use the not so trustworthy sources, skip through important steps, and so on, can lead to issues with unwanted programs. This program also gets dropped when users encounter fake Flash Player installers online |

| Repair | You can properly repair the functions of the affected machine with a tool like FortectIntego that indicates and possibly fixes corrupted parts |
WebAssistSearch virus gets promoted via rogue applications or setups, so you get the adware program installed without knowledge or permissions. This PUP runs intrusive and aggressive advertising campaigns, so experts[2] always note to avoid banners, pop-up ads, coupons, and redirects that you receive out of nowhere. Anything that is not originating from the site that you visit at the time should be considered suspicious or even possibly malicious.
When you receive any pop-ups, ads, redirects, and banners marked with Ads by WebAssistSearch or other names of programs you do not use on purpose, you need to consider the PUP infiltration as the reason behind these issues. Potentially unwanted programs can control various processes and affect functions while triggering the behavior while running in the background of the system.
WebAssistSearch is identical to other shady applications that appear out of nowhere and trigger an unwanted process on your macOS device. It looks and behaves like Central Locator, SearchMainInfo, CreativeSearch, StudyGeneral, MainReady, DataQuest, SearchWebSvc, or any other Mac malware that is based on adware-type symptoms.
All these mentioned applications and other programs similar to this intruder can be terminated, even though it is not that easy to achieve. You can remove WebAssistSearch, and you should do that as soon as you possibly can because it can be detected[3] by AV tools and security programs. You need to rely on such applications and clean the machine from any suspicious apps. 
Besides the automatic WebAssistSearch removal process with anti-malware tools compatible with your macOS, you may need to go through web browser settings and installations there. It is important because PUP triggers install of some tensions, toolbars, add-ons, and so on. To clear those questionable programs, you can either manually remove and block the content or reset browsing tools fully to default by relying on the steps below.
As for the proper system performance and speed issues that can be caused by the WebAssistSearch and other related intruders, you need to pay attention to system recovery tools, optimizers, and so on. There are many ways that can help you improve the performance, but anti-malware tools only rely on system cleaning, so get a program designed for the macOS optimization like FortectIntego, run the system check, and possibly repair affected startup files, other functions needed for the best performance.
Pay attention when installing freeware, so you can avoid PUPs
There are many ways how potentially unwanted programs can spread around, and the bundling method is one of the more common techniques. Software providers pack their products with PUPs and list them as optional installs. When the person agrees to install any program and goes for the recommended or quick options, all included apps get loaded automatically,
You need to opt dor Advanced or Custom installations and de-select anything that raises questions or is suspicious. This way you get to control the installations and what programs get to access your device. These additional programs are not fully disclosed, in most cases, so you need to pay attention to every detail.
Terminating WebAssistSearch PUP properly requires attention
WebAssistSearch virus is the shady program that gets installed behind your back, so there is no easy way to find and fully delete the application. Even though you can notice the application added in some folders or on the desktop, you need to delete the intruder with all the associated files and programs.
For that purpose, you need tools that can remove WebAssistSearch properly without much effort. Anti-malware tools are designed to check various places on the system where these applications get injected. You need to check the system for other malicious apps, so Av engines are the best for that.
WebAssistSearch removal can be quick if you follow steps suggested by the AV engine you use. The system gets cleaned, and speed, performance issues should be the thing of the past. Unfortunately, for the system improvement, you need additional help from repair tools.
