How to remove the MegaGuard adware-type browser extension
Written by Tomas Meskauskas on (updated)
What kind of software is MegaGuard?
MegaGuard is an adware-type browser extension that is endorsed as a security tool that prevents access to suspicious websites. Adware stands for advertising-supported software, its purpose is to generate revenue for its developers/publishers through advertising. Additionally, MegaGuard spies on users' browsing activity and redirects users to bangsearch.pro fake search engine.
MegaGuard adware overview
Typically, adware places third-party graphical content (e.g., pop-ups, surveys, overlays, coupons, banners, etc.) on visited websites, desktops, or other interfaces. These advertisements can endorse online scams, untrustworthy/harmful software, and even malware. When clicked on, some of the ads can execute scripts to perform sneaky downloads/installations.
It is also noteworthy that MegaGuard adware employs the "Managed by your organization" feature to make the removal process more troublesome.
Remember that any genuine content encountered through these adverts is most likely promoted by scammers who abuse its affiliate programs to obtain illegitimate commissions.
Specific conditions may be necessary for software within this classification to operate as intended (e.g., compatible browser/system specs, visits to particular websites, etc.). However, regardless of whether MegaGuard displays advertisements – it endangers device and user safety.
What is more, this adware-type browser extension has data-tracking functionalities. Advertising-supported software usually targets the following data: visited URLs, viewed webpages, searched queries, Internet cookies, usernames/passwords, personally identifiable details, finance-related information, and so forth. The collected data can be sold to third-parties or otherwise abused for profit.
In summary, the presence of software like MegaGuard on devices may lead to system infections, severe privacy issues, financial losses, and even identity theft.

Adware examples
We have written about thousands of adware-type browser extensions and applications; Three Seconds AdBlock Lite, profilingTime, and Navigate Buddy are merely a few of our newest articles.
Advertising-supported software usually appears legitimate and innocuous. It can entice users to download/install by promising various useful features. However, these functions seldom work as promised, and in most cases – they are utterly nonoperational.
It must be stressed that even if a piece of software works exactly as indicated by its promotional material – that is not a guarantee of either legitimacy or safety.
How did MegaGuard install on my computer?
Adware is endorsed on legitimate-looking promotional pages and scam sites. They are primarily accessed through redirects generated by websites utilizing rogue advertising networks, intrusive ads, spam browser notifications, misspelled URLs, and installed adware (with browser force-opening capabilities).
The bundling marketing tactic, which involves packing ordinary program installation setups with unwanted/malicious additions – is also used to distribute adware.
Downloading from freeware and free file-hosting sites, Peer-to-Peer sharing networks, and other suspect sources – poses a threat of bundled content infiltrating the system. The risk is further compounded by treating installation processes with negligence (e.g., ignoring times, skipping sections, using "Easy/Express" settings, etc.).
Some intrusive advertisements can be triggered (i.e., by being clicked) to execute scripts that perform downloads/installations without user permission. These adverts proliferate advertising-supported software as well.
How to avoid installation of adware?
We recommend researching software and downloading it only from official/verified channels. Additionally, installation processes must be approached with caution by reading terms, studying available options, using the "Custom/Advanced" settings, and opting out of all supplementary apps, tools, extensions, features, etc.
We also advise being careful while browsing, as fake and malicious online content typically appears genuine. For example, while intrusive ads may look ordinary/innocuous – they redirect to unreliable and questionable websites (e.g., scam-promoting, gambling, adult dating, pornography, etc.).
In case of continuous encounters with such adverts/redirects, check the device and immediately remove all suspicious applications and browser extensions/plug-ins. If your computer is already infected with MegaGuard, we recommend running a scan with Combo Cleaner Antivirus for Windows to automatically eliminate this adware.
