How to uninstall the REGSERVO unwanted application?
Written by Tomas Meskauskas on (updated)
What is REGSERVO?
REGSERVO is a rogue application, endorsed as a tool capable of detecting and removing threats/issues present on operating systems. Due to the dubious techniques used to distribute this app, it is classified as a PUA (Potentially Unwanted Application).
Software within this classification is typically unable to perform the promised functionalities, and it may have harmful abilities instead.
While questionable distributed methods might be used to promote legitimate products, they are more commonly employed to proliferate undesirable and malicious software. PUAs are spread using such tactics.
These applications usually appear ordinary and innocuous. They also offer various "useful" and "advantageous" features.
However, the functions seldom work as advertised, and in most cases - they do not work at all. Fake anti-viruses are prime examples of this type of PUAs. Products within this classification require activation (i.e., purchase) to have their functionalities enabled, yet after activation - they remain nonoperational.
Furthermore, PUAs often have unmentioned, heinous abilities. Unwanted apps can force-open promotional/sale-based, misleading, rogue, untrustworthy, deceptive/scam, compromised, and malicious sites.
PUAs categorized as adware run intrusive advertisement campaigns. The delivered ads diminish the browsing experience and endanger device/user safety.
When clicked on, intrusive adverts redirect to unreliable/dangerous websites, and some can stealthily download/install software. Browser hijackers are another type of PUAs. They operate by making modifications to browser settings and limiting/denying access to them - in order to promote fake search engines.
These web searching tools rarely can generate search results, so they redirect to Yahoo, Bing, Google, and other legitimate search engines. What is more, most PUAs (regardless of type) can track data.
They record browsing activity (visited URLs, viewed webpages, searched queries, etc.) and gather sensitive information inferred from it (IP addresses, geolocations, and personally identifiable details). The collected data is then monetized by being shared with and/or sold to third-parties (potentially, cyber criminals).
To summarize, the presence of unwanted apps on devices - can result in system infections, severe privacy issues, financial losses, and even identity theft. Therefore, it is strongly advised to remove all suspect applications and browser extensions/plug-ins immediately upon detection.

SpeedFixTool, Registry Medic, PC Optimizer Pro, and Garbage Cleaner are some examples of unwanted applications akin to REGSERVO. Despite their legitimate appearance and the "handy" functionalities they offer - these apps are considered to be a threat to device and user safety.
The sole purpose of PUAs is to generate revenue for the developers; to users - they have no real value. Instead of delivering on any promises, PUAs can cause redirects, run intrusive advertisement campaigns, hijack browsers, and collect private information.
How did potentially unwanted applications install on my computer?
PUAs are spread through downloaders/installers of other programs. This deceptive marketing technique of pre-packing regular software with unwanted or malicious additions - is called "bundling".
Rushed download/installation processes (e.g., ignored terms, skipped steps and sections, used "Easy/Express" settings, etc.) - increase the risk of unintentionally allowing bundled content into the system. Intrusive advertisements are used to proliferate PUAs as well.
Once clicked on, the ads can execute scripts to download/install these applications without user consent. PUAs may also have "official" promotional/download sites.
How to avoid installation of potentially unwanted applications?
It is highly recommended to research software products prior to download/installation and/or purchase. Additionally, all downloads must be done from official and verified sources.
Untrustworthy download channels, e.g., unofficial and free file-hosting (freeware) websites, P2P sharing networks (Torrent clients, Gnutella, eMule, etc.), and other third-party downloaders - often offer hazardous and bundled content. When downloading/installing, it is advised to read terms, study available options, use the "Custom/Advanced" settings, and opt-out from additional apps, tools, functions, etc.
It is just as important to exercise caution when browsing. Intrusive adverts appear ordinary and harmless; however, they redirect to questionable webpages (e.g., gambling, pornography, adult-dating, and so forth). In case of encounters with such ads and/or redirects, the system must be checked and all suspicious applications and browser extensions/plug-ins detected - removed from it without delay.
If your computer is already infected with PUAs, we recommend running a scan with Combo Cleaner Antivirus for Windows to automatically eliminate them.
