mBytes Speedup Pro – system optimizer that comes bundled with other rogue tools

mBytes Speedup Pro – a system tool that delivers false-positive results reporting about malware or computer problems to trick people into installing additional applications or purchasing useless software. This is a potentially unwanted application[1] that comes packed as an additional installation with Driver Updater or any other PCVARK product. System optimizers that come as an extra tool for the system performance shouldn't be trusted because the main purpose of such rogue applications is to convince people that their system has problems or is infected with malware.
The fake tool claims to optimize and speed up your PC, but to achieve that and clean the machine from indicated malware, you need to buy the full licensed version for 39.95 euros. Unfortunately, the purchased version also does nothing and only runs on additional PC resources to perform false system scans.

This potentially unwanted program often gets called a mBytes Speedup Pro virus because it appears out of nowhere since PUPs are silent intruders. Although this is not a virus or serious malware that could damage your machine, system optimization tools, or any fake applications like this alter relevant system preferences like the registry.
The article's culprit, in general, focuses on tricking the user into purchasing the full version of the tool or calling the number provided on the warning pop-ups. This optimizer gets installed on the machine and starts reporting issues detected on the system, shows the list of malware, performance, startup, or driver errors and problems.
Then mBytes Speedup Pro claims to fix these issues if you purchase the full version of the application, pay up to 40$ for the activation key. Selling their software is the primary intention of PCVARK – PUP developers. Also, people behind such software offer to call the toll-free number for support. These are tactics common for various scams.[2]
You cannot notice the initial installation of the PUP because it comes as an addition to other useless applications and gets automatically installed from a pack of programs. There are a few things you can encounter that indicate suspicious infiltration:
- questionable processes running on Task manager;
- commercial content banners, pop-ups, redirects;
- the slowness of the machine;
- additional browser content installed without your permission.

Be aware that mBytes Speedup Pro comes bundled with other registry cleaners, system tools, and potentially unwanted programs. Experts[3] always note how crucial it may be when you choose your software sources without considering the risks.
The bogus system tool has various methods that developers may use for the distribution:
- bundles with other PUPs or freeware;
- promotional advertisements;
- free download pages;
- official developers site.
No matter how you got this application, either it is installed with your consent because you fell for the promotional message or it came with the help of software bundling, you need to get rid of it as soon as possible. This is useless, and there is no reason to keep such rogue applications on the machine.
Additionally, to the suspicious claims and false scan results, this tool has another feature that should make you eager to remove mBytes Speedup Pro as soon as you can – data tracking. This is a standard function for other PUPs because all of them are related to advertisers and commercial content creators who need data like IP addresses, location, or browsing history for their malvertising campaigns.
Get a reliable tool such as MalwarebytesMalwarebytes or SpyHunterCombo Cleaner, that is capable of removing malware and cleaning the system. Choose the official provider or developer, another trustworthy source, and scan the system with the program to perform PUP removal. Then you can additionally clean the damage with FortectIntego and improve the performance for real.

Suspicious system tools come bundled with other PUPs
The internet is filled with tons of promotional content that pushes applications, browser extensions, and tools that supposedly improve the performance of a device. Banners, pop-ups, redirects, and other material that loads on the screen may trick you into installing programs you don't need.
Unfortunately, such installations triggered by advertisements, in most cases, include additional programs that can even be malicious or harmful for the machine. This is also an issue when applications are installed from questionable pages and p2p services.
You can avoid these infiltrations if you choose official providers, developers' websites, and read the Privacy Policy or EULA on the page. Also, if you go for Advanced or Custom installation options, you can see the full list of extra programs and de-select suspicious tools or PUPs included.
Clean the machine and remove mBytes Speedup Pro virus from the system with anti-malware tools
Any potentially unwanted program like this system optimizer has frustrating and intrusive features, so mBytes Speedup Pro removal requires a full system scan during which all intruders, corrupted files, and other performance issues get indicated, detected, and removed from the system entirely.
You can try to uninstall the PUA manually, but there are many more issues regarding the intruder since it is created by the developer that has many other rogue tools under his sleeve. You should remove it with reliable anti-malware tools and clean the system from any traces of the infection.
