How to uninstall mBytes System Care from your computer
Written by Tomas Meskauskas on (updated)
What is mBytes System Care?
mBytes System Care is one of many tools that supposedly optimizes operating systems and keeps them running smoothly without errors.
In fact, this program is promoted by including it into set-ups of other software. People usually download and install these bundled programs unintentionally. For this reason, mBytes System Care belongs to the category of potentially unwanted applications (PUAs).
mBytes System Care is supposedly capable of removing unwanted and malicious programs, enhancing system performance, cleaning unnecessary files, and so on. This, however, cannot be done without purchasing (activating) the software. Do not trust programs that are bundled into the set-ups of other software.
They often detect 'issues' that are fabricated by the programs that detected them in the first place. These programs are used to deceive people into purchasing software by listing fake problems that they will supposedly fix. It is unknown whether mBytes System Care is one of these rogue programs, however, this is a strong possibility.
Furthermore, developers often bundle more than one PUA into set-ups. Therefore, mBytes System Care might be promoted together with browser hijackers, adware-type apps, and other unwanted applications. Browser hijacker apps modify browser settings to advertise dubious/fake search engines.
Additionally, they gather information relating to users' browsing habits. For example, IP addresses, URLs of visited websites, entered search queries, geolocations, and other similar data. Developers send the data to other people (potentially, cyber criminals) who misuse it to generate revenue.
Adware is software that serves users with ads such as coupons, banners, surveys, pop-ups, and so on. Do not click these ads, since they cause redirects to dubious web pages or run scripts that download/install PUAs. In summary, apps of this type might cause problems with browsing safety, privacy, or even lead to identity theft.

mBytes System Care is just one of many PUAs online. Some examples are Inlog Optimizer, Free Online Manuals, and Xtron System Care. Most of these programs are promoted by bundling them into set-ups. The developers advertise them as legitimate apps, however, do not trust apps that are downloaded and installed unintentionally.
How did potentially unwanted applications install on my computer?
PUAs can be downloaded and installed unintentionally when users click deceptive ads that run scripts, which cause this problem. In other cases, PUAs are downloaded and installed together with other (usually free) programs. This happens, since developers bundle them into set-ups of regular software and do not disclose this information properly.
They hide the details in "Custom", "Advanced" and other similar setup parts. If these settings are not changed, PUAs are downloaded and installed together with other software bundled into the setup.
How to avoid installation of potentially unwanted applications?
Use only official and trustworthy websites when downloading software. Peer-to-Peer networks, unofficial sites, third party downloaders and other similar sources of this kind should not be used. Inspect each download/installation setup, check "Custom", "Advanced" and other settings. Deselect offers to download or install PUAs.
Many intrusive ads redirect users to untrustworthy websites - these ads are usually displayed on sites relating to gambling, pornography, adult dating, etc. Do not click these ads. If ads appear regularly or the browser opens dubious sites automatically, check the browser for unknown/unwanted plug-ins, add-ons, and extensions, and remove them immediately.
Also check for unwanted programs installed on the operating system and uninstall them. If your computer is already infected with PUAs, we recommend running a scan with Combo Cleaner Antivirus for Windows to automatically eliminate them.
