How to uninstall Full System Care from the operating system
Written by Tomas Meskauskas on (updated)
What is Full System Care?
Full System Care is advertised as software that cleans, optimizes, and improves computer performance. In fact, this program is distributed through the download and/or installation set-ups of other programs. People often download and install software of this type unintentionally. Therefore, Full System Care is categorized as a potentially unwanted application (PUA).
Full System Care supposedly removes potentially unwanted items such as those impacting the system (and startup), installed software limiting performance, and items leaving the system vulnerable to malicious attacks. To remove 'detected items', however, users must activate Full System Care software (i.e., purchase the full version).
As mentioned, Full System Care is a potentially unwanted application - apps of this type should not be trusted. Even if activated, Full System Care will not remove any unwanted items, improve system performance, etc.
These PUAs supposedly detect various issues, which can be fixed by the full version, thereby tricking users into believing that their computers will run faster, without errors, and so on. Additionally, Full System Care is used to promote another PUA called Advanced Driver Booster.
PUAs are commonly distributed together with other software of this kind. For example, browser hijackers, adware, etc. There is a strong possibility that people who install Full System Care will also be tricked into installing other PUAs. Browser hijackers are apps that change browser settings so that users are forced to use/visit fake search engines or dubious websites.
PUAs also record user information such as IP addresses, geolocations, addresses of visited websites, entered search queries, and other browsing-related details. PUAs can also record personal, sensitive details. Developers share the data with third parties (potentially, cyber criminals) who misuse it to generate revenue.
Furthermore, Full System Care might be distributed with adware. If installed, adware-type apps feed users with coupons, banners, surveys, pop-up ads and other intrusive content. If clicked, these can redirect people to untrustworthy websites or execute scripts that cause download/installation of unwanted, potentially malicious software.

| Supposed Functionality | Full System Care supposedly cleans, optimizes, and improves operating system performance. |
| Detection Names | Avast (Win32:Malware-gen), BitDefender (Gen:Variant.Application.Deceptor.Slv.1), ESET-NOD32 (A Variant Of Win32/GT32SupportGeeks.U Potentially Unwanted), Kaspersky (Hoax.Win32.DeceptPCClean.ksx), Full List Of Detections (VirusTotal) |
| Symptoms | A program that you do not recall installing suddenly appeared on your computer. A new application is performing computer scans and displays warning messages about 'found issues'. Asks for payment to eliminate the supposedly found errors. |
| Distribution Methods | Deceptive pop-up ads, free software installers (bundling), fake Flash Player installers. |

Xbits Speedup Pro, Xtron PC Speedup, and Xtron Optimizer Pro are just some examples of programs that are virtually identical to Full System Care. These and other programs are classified as PUAs. We advise against paying for activation of software known as PUAs.
Furthermore, developers distribute this software with other unwanted programs (browser hijackers, adware, and so on). Do not use these programs and remove them immediately.
How did potentially unwanted applications install on my computer?
In most cases, people download and install PUAs accidentally through deceptive ads that, when clicked, run scripts designed to download and/or install them, or through the set-ups of other (mostly free) programs. PUAs are often included in the set-ups as additional offers, however, related information is not properly disclosed.
Developers hide the details in options such as "Custom", "Advanced", and so on. Unfortunately, many people fail to check these settings and leave them unchanged. This leads to download/installation of regular software together with PUAs by default.
How to avoid installation of potentially unwanted applications
Download software using only official websites and direct links. Third party downloaders, installers, Peer-to-Peer networks such as torrent clients, eMule, dubious, unofficial websites and other similar sources tools should never be used.
If download or installation setup contains "Custom", "Advanced" or other settings of this kind, ensure that they are checked, and changed if necessary. Dismiss any offers to download or install unwanted software before completing download or installation. Avoid clicking advertisements displayed on dubious websites.
Typically, these ads open untrustworthy (potentially malicious) websites or cause download/installation of unwanted programs. The ads might also appear on legitimate websites. Remove any unwanted, suspicious or unknown applications (extensions, plug-ins, add-ons) installed on the browser immediately.
The same should be applied to programs of this type installed on the 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.
