WinThruster removal instructions
What is WinThruster?
WinThruster is presented as a program which fixes issues, makes other programs to load faster and optimizes computers in one click. It is known that WinThruster's developers promote it by bundling this program into other software's setups. This increases the possibility that most people download and install it unintentionally. For this reason WinThruster is categorized as a potentially unwanted application (PUA).
When WinThruster finishes scanning the system, it displays a list of issues. By fixing detected problems users should be able to improve computer's performance. However, in order to start fixing them it is requited to register the program, in other words, to purchase a full version. There are many apps that do not solve the detected problems for free, however, quite often those problems are not real as well. There are many apps that are designed to give users an impression that there are many issues on their computers and they can be fixed by using a particular program. However, in order to fix them they are encouraged to buy them first. There is no information whether WinThruster is one of these apps or not, however, quite often apps that are promoted by including/adding them into setups of other software are. Besides, developers usually bundle more than one app, there are many cases where other bundled apps are various adware-type apps, browser hijackers and so on. PUAs of this kind usually are designed to gather information related to user's browsing activities. For example, geolocations, entered search queries, URLs of visited websites, IP addresses and so on. Their developers share all of it with other parties, potentially, cyber criminals who misuse it to generate revenue. Another common issue with PUAs is intrusive ads. They display various coupons, banners, surveys, pop-up ads and so on that, if clicked, open shady websites. In some cases these ads execute scripts designed to download and install various unwanted apps. PUAs of this kind should be removed as soon as possible, people who use them might experience problems related to privacy, browsing safety or even identity theft.

We do not recommend to use apps that are being downloaded and installed inadvertently. Besides, quite often they do not provide their users with any promoted features, tools and so on.
How did potentially unwanted applications install on my computer?
WinThruster has a download website. However, it is very likely that most users download and install it unintentionally. As we mentioned in our introduction, this app is promoted by bundling it into other software's setups. However, developers do not expose information about it properly. They hide bundled applications in "Custom, "Advanced" settings (or other sections) of software download or installation setups. There are many users who leave all these settings unchecked and unchanged, by doing so they often allow for PUAs to be downloaded and installed together with some other, intentionally downloaded/installed software. In some cases unintentional downloads and installations happen when people click intrusive ads designed to run scripts that cause them.
How to avoid installation of potentially unwanted applications?
We recommended to be cautious when browsing the web and downloading and installing various software (especially if it is free). Do not finish any download or installation without checking all available "Custom" or "Advanced" (or other similar) settings and dismissing offers to download/install unwanted applications. Download software from official/trustworthy websites and use direct download links. Tools like Peer-to-Peer networks (torrent clients, eMule etc.), unofficial websites and other similar sources should not be used to download any software. Moreover, we recommend not to click various intrusive advertisements, especially if they are displayed on pages related to gambling, pornography, adult dating and other dubious sites. If unwanted redirects and ads occur regularly, then check what are the installed programs on operating system and applications (extensions, plug-ins or add-ons) on a browser. Remove all unwanted, unknown entries immediately. If your computer is already infected with PUAs, we recommend running a scan with Spyhunter for Windows to automatically eliminate them.
