Qbit PC Speedup Unwanted Application
Written by Tomas Meskauskas on (updated)
What is Qbit PC Speedup?
The Qbit PC Speedup program is promoted by its developers as a computer optimization tool. It supposedly ensures that computers run smoothly, fast, and without errors, however, Qbit PC Speedup is classified as a potentially unwanted application (PUA).
Developers promote this app using a deceptive marketing method called "bundling". Therefore, it is usually installed unintentionally without users' knowledge.
Qbit PC Speedup offers a free scan that searches for various issues, however, none of the detected 'problems' can be fixed without purchasing the full version of this tool. PUAs promoted using the "bundling" method often detect fake issues.
They display fake scan results to trick people into believing that there are problems that should be fixed, and that only their tool can address them (if purchased). It is possible that Qbit PC Speedup is one of these rogue programs.
Furthermore, software developers often bundle more than one program, and thus browser hijackers, adware-type, or other PUAs might also have been installed together with Qbit PC Speedup. Once installed, these apps gather browsing-related information such as IP addresses, geolocations, entered search queries, URLs of visited websites, and so on.
Their developers share the information with third parties who misuse it to generate revenue. Note, some of these parties might be cyber criminals, and some of the collected information might contain personal details. Furthermore, adware-type apps often deliver intrusive ads such as coupons, banners, surveys, pop-up ads, and so on.
These can be annoying (they conceal underlying content of visited websites). Clicking them often leads to dubious websites and they can sometimes execute scripts that download and install unwanted, potentially malicious apps.

Typically, users are tricked into installing PUAs when developers promote them as 'useful' programs (optimizers, cleaners, and so on), however, these apps deliver no real value and are designed only to generate revenue. Furthermore, they are often installed together with other apps that can cause privacy, browsing safety issues, and other problems.
Qbit PC Speedup is similar to Total System Care, SecureDossier, Registry Scanner, and many other rogue programs.

How did potentially unwanted applications install on my computer?
As mentioned above, most potentially unwanted applications are distributed via "bundling", a deceptive marketing method used to trick people into unintentional download and installation of PUAs. Developers achieve this by hiding PUAs in "Custom", "Advanced", and other settings.
Software developers avoid disclosing information about bundling of unwanted apps being and hope that users will not notice them. Unfortunately, many users skip download and installation steps and do not check the settings. In doing so, they allow PUAs to be installed without their knowledge.
How to avoid installation of potentially unwanted applications?
You are advised to download software using official, trustworthy websites and direct links. Do not use torrents, third party software downloaders, unofficial websites, or other similar sources. Download and install software with care: check included "Custom", "Advanced", and other settings.
Deselect or opt-out of all potentially unwanted applications (offers to download or install them) and only then finish the download/installation process. Do not click ads displayed on dubious pages, since they often redirect users to malicious sites relating to gambling, adult dating, pornography, and so on.
They can also trigger installation of unwanted applications. If you encounter unwanted ads or redirects, check the list of add-ons, extensions, and plug-ins installed on your browser and remove suspicious/unwanted entries immediately. The same applies to programs installed on your computer (operating system).
If your computer is already infected with PUAs, we recommend running a scan with Combo Cleaner Antivirus for Windows to automatically eliminate them.
