Remove MegaBackup virus from Mac OS X


Get a fix for the MegaBackup issue that results in annoying popups appearing on the infected Mac machine and ads being embedded in web pages.

Update: October 2018

MegaBackup exemplifies misleading software that attempts to convince Mac users to purchase the license under false pretenses. Its graphical user interface deceitfully states that thousands of files are unprotected and recommends urgent backup in order to allegedly secure data from “potential system crash, accidental file deletion or hard drive damage”. Under this entire aura of good intensions, though, there lurks a ruse that not everyone can discern. To start with, this application hardly ever uses conventional installation methods – instead, it gets into systems as a component of bundled setups where the inclusion of the extra item is covert. This is exactly why most users suffering from the adverse consequences of this attack cannot recall allowing MegaBackup to get into their Macs.

Furthermore, this app invokes a number of effects upon the Internet browsing facet of computer usage. In particular, it may add an extension to Safari as well as the Mac-adjusted variants of Chrome and Firefox, while the administrator on the box, again, is not requested for approval. Said add-on is tasked with inserting a variety of advertising content into pages that the victim visits. Ultimately, regular sites will be filled up with coupons, special offers, deals, banners, price comparison charts and inline text. To cap it off, interstitial ads are also likely to recurrently pop up when you are navigating from one page to another.

MegaBackup also generates tons of warning notifications that try to frighten the user into believing that resorting to the app’s services is a must. These alerts emphasize the volume of personal information that’s purportedly at risk, stating that loads of photos, documents, music files, desktop items and downloads can be completely obliterated in case something goes wrong with the hardware. The popups get too nagging to endure over time, so MegaBackup removal gets on every infected person’s agenda at the end of the day.

Yet another adverse facet of the MegaBackup malware is that it usually sneaks into a Mac computer along with other potentially unwanted programs (PUPs). Aside from the brainwashing effects stemming from the culprit in question, victims have reported additional issues with browser redirects to Weknow.ac a rogue search engine. This is a malicious web traffic interception and monetization technique that results in a browser hijack and significantly diminishes user experience. To add more insult to injury, the virus is often accompanied by a fake Mac system utility called MacKeeper, which will generate a bevy of nag screens, deceptive problem detection reports and pseudo system scans in order to persuade the victim to purchase its license.

Ultimately, the onset of MegaBackup is a red flag indicating a multi-vector attack, so it certainly makes sense to examine the host Mac for different types of malware thoroughly and get rid of the threats.
