Removal instructions for the Sebux adware-type browser extension
Written by Tomas Meskauskas on (updated)
What kind of software is Sebux?
While investigating deceptive sites, our researchers discovered the Sebux rogue browser extension. After analyzing this piece of software, we determined that it is adware. Sebux runs intrusive advertisement campaigns and spies on users' browsing activity.
Sebux adware overview
Adware stands for advertising-supported software. It enables the placement of third-party graphical content (e.g., pop-ups, overlays, surveys, banners, etc.) on visited websites and/or other interfaces.
Note that software within this classification might require certain conditions to deliver intrusive advert campaigns (e.g., compatible browser/system or user geolocation, visits to specific sites, etc.). However, even if Sebux does not display ads – its presence remains a threat.
Adware-delivered advertisements primarily promote online scams, unreliable/harmful software, and even malware. When clicked on, some of these adverts can execute scripts to perform stealthy downloads/installations. Keep in mind that any genuine content encountered through these ads is most likely endorsed by scammers who abuse its affiliate programs to obtain illegitimate commissions.
Furthermore, Sebux has data-tracking abilities. Information of interest may include: URLs visited, webpages viewed, search queries typed, Internet cookies, usernames/passwords, personally identifiable details, finance-related data, and so forth. The collected information can then be monetized via sale to third-parties.
To summarize, advertising-supported software like Sebux may cause system infections, serious privacy issues, financial losses, and identity theft.

Adware examples
Disable Ads, Go Blocker, Fetchzilla, and AdAssistant are merely some examples of adware that we have examined recently.
Advertising-supported software tends to look ordinary and harmless. Users are enticed into downloading/installing adware by promises of various "useful" and "advantageous" functionalities. However, these features seldom work as promised, and in most cases – they are utterly nonoperational.
It must be stressed that even if a piece of software works as indicated by its promotional material – that is not definitive proof of legitimacy or safety.
How did Sebux install on my computer?
We acquired Sebux from its "official" promotional page. In addition to such sites, adware is commonly endorsed on scam webpages. Most visitors access these pages via redirects generated by websites that utilize rogue advertising networks, mistyped URLs, spam browser notifications, intrusive ads, or installed adware (with browser force-opening capabilities).
Advertising-supported software can also be bundled with (packed alongside) regular programs. Downloading from untrustworthy sources (e.g., freeware and third-party sites, P2P sharing networks, etc.) and treating installations with negligence (e.g., skipping steps, using "Quick/Easy" settings, etc.) – increase the risk of allowing bundled content into the device.
Adware is proliferated by intrusive advertisements as well. Some of these adverts can be triggered (i.e., by being clicked) to execute scripts that perform downloads/installations without user permission.
How to avoid installation of adware?
It is essential to research software prior to downloading or purchasing it. Furthermore, all downloads must be performed from official and verified channels. When installing, we recommend reading terms, inspecting available options, using the "Custom" or "Advanced" settings, and opting out of all additions (e.g., apps, extensions, tools, etc.).
We also advise being vigilant while browsing since fake and dangerous online content typically appears legitimate and innocuous. For example, intrusive ads may look harmless – yet redirect to unreliable and questionable websites (e.g., gambling, scam-promoting, pornography, adult dating, etc.).
If you keep encountering advertisements and/or redirects of this kind, check the device and immediately remove all dubious applications and browser extensions/plug-ins. If your computer is already infected with Sebux, we recommend running a scan with Combo Cleaner Antivirus for Windows to automatically eliminate this adware.
