Removal instructions for the SecuriGuard potentially unwanted application
Written by Tomas Meskauskas on
What kind of application is SecuriGuard?
While browsing suspicious websites, our researchers discovered the SecuriGuard app. It is endorsed as a browser with improved security and privacy features.
Upon analysis, we determined that SecuriGuard is a PUA (Potentially Unwanted Application). Apps within this classification typically have harmful capabilities and may infiltrate systems alongside other suspect software.
Potentially unwanted application overview
SecuriGuard's installer lists its capabilities as "using all system resources". Further clarification is not provided – hence, it is unclear which resources and for what purposes this app employs. However, software that operates in a manner that consumes a lot of system resources can significantly diminish system performance and browsing quality.
As mentioned in the introduction, potentially unwanted applications tend to have hazardous abilities. Data tracking is by far the most prevalent, and it can be used to gather browsing histories, Internet cookies, usernames/passwords, personally identifiable details, credit card numbers, and other sensitive information. This vulnerable data can be sold to third-parties or otherwise abused for profit.
PUAs can also operate as adware. Software within this classification typically displays advertisements on visited websites, desktops, or other interfaces. These ads promote deceptive and malicious content. Some can even be triggered (by being clicked) to execute scripts that perform stealthy downloads/installations.
Unwanted apps may function as browser hijackers as well. Hijacker software modifies browser settings (e.g., default search engine, homepage, new tab/window, etc.) to generate redirects to promoted sites.
Usually, the endorsed websites are fake search engines that cannot provide search results and redirect to legitimate Internet search sites. Even if a fraudulent search engine can produce search results – they are inaccurate and may include sponsored, deceptive, and possibly dangerous content.
To summarize, presence of unwanted software on devices can lead to system infections, serious privacy issues, financial losses, and identity theft.

Potentially unwanted application examples
We have written about countless PUAs; StealthGuard – is an example of an app similar to SecuriGuard, and EpiStart (EpiBrowser), Woiap WApp, Kowi SApp, Traw Dapp – are just a couple of our latest articles on these applications.
This software is usually disguised as legitimate and harmless, such as browsers, system utility tools, anti-viruses, media players, and so on. Yet unwanted applications seldom function as promised; all their features tend to be nonfunctional.
It must be stressed that even if a piece of software operates exactly as indicated by its promotional material – that is not definitive proof of either legitimacy or safety.
How did potentially unwanted applications install on my computer?
SecuriGuard has an "official" promotional webpage, and it is endorsed on deceptive sites. Such pages are primarily accessed via redirects caused by intrusive ads, websites employing rogue advertising networks, spam browser notifications, mistyped URLs, and installed adware (with browser force-opening abilities).
The bundling marketing tactic, which involves packing ordinary program installers with unwanted/malicious supplements – is also used to proliferate PUAs.
These pre-packed installation setups can be downloaded from freeware and free file-hosting sites, Peer-to-Peer sharing networks, and other suspicious sources. The risk of allowing bundled content into the device is furthered by rushing through installations (e.g., ignoring terms, skipping steps and sections, using the "Easy/Quick" settings, etc.).
Additionally, unwanted software is spread by intrusive adverts. Once clicked on, some of the advertisements can execute scripts to perform downloads/installations without user permission.
How to avoid installation of potentially unwanted applications?
It is important to always research software before downloading/purchasing. All downloads must be performed from official and trustworthy channels. When installing, we recommend studying terms and options, using the "Custom" or "Advanced" settings, and opting out of additional apps, extensions, etc.
Another recommendation is to be careful while browsing since fake and malicious online content usually appears legitimate and innocuous. For example, despite their harmless appearance – intrusive ads redirect to highly questionable websites (e.g., scam-promoting, gambling, adult dating, etc.).
Should you keep experiencing advertisements/redirects of this kind, check the device and immediately remove all suspect applications and browser extensions/plug-ins. If your computer is already infected with PUAs, we recommend running a scan with Combo Cleaner Antivirus for Windows to automatically eliminate them.
