How to remove OptiBuy virus ads from Mac

Get rid of ads powered by OptiBuy, learn why this app is categorized as adware and what kind of problems may ensue from its activity on an infected Mac.

The OptiBuy application (aka MySoftUpdate, MySoft Update, My-Soft-Update or MacUpdater) tailored to run on Mac computers is far from fitting in the paradigm of legit digital services. Its unscrupulous developers chose to cash in on hijacking browsers and thus benefit from scattershot display of obnoxious advertisements. In other words, the crooks get the bang for their buck at the expense of people’s online experience. The aggressive code adds a JavaScript backed virtual layer to web pages visited via Safari, Firefox or Chrome on Mac. This stealth layer gets inundated with various third-party content labeled “Ads by OptiBuy”, “Powered by OptiBuy”, “Brought to you by OptiBuy”, or “OptiBuy ads”. These unwelcome items include coupons, deals, comparison shopping assistants, in-text links and interstitial ads that keep popping up all of a sudden and stay open in the background, eating up the plagued machine’s resources.

OptiBuy homepage is misleading to the bone

It’s not uncommon for adware programs to have “official” websites set up. The one under scrutiny is no exception. Incidentally, its homepage is a replica of the site for SurfBuyer, which is another ad-injecting virus from the same lineage. There is a great deal of sarcasm in OptiBuy’s motto that reads, “Become a Smart Online Shopper”. The web page also has some legal implications. Its Terms & Conditions section actually gets the true gist of the adware straight, emphasizing that it’s free to use but ad-supported. However, there is hardly any chance for users to peruse the EULA as the application is being installed. The reason is that this ad-serving malware propagates by means of a tricky mechanism called bundling. It slithers its way into a Mac alongside other programs, which tend to be harmless and free of charge. So would-be victims never get to authorize the potentially unsafe setup, simply because they are unaware of the menace taking effect behind the scenes. Another possible entry point for OptiBuy trespass revolves around the use of such rogue programs as MySoftUpdate or MacUpdater. When running on a Mac, these malicious apps can promote opportunistic infections camouflaged as critical software updates.

OptiBuy utilizes persistence techniques to stay inside a contaminated Mac computer and thwart removal through commonplace methods. Consequently, eliminating the associated browser plugin or extension is not going to fix the problem altogether. The underlying process that resides deep down the system will keep executing the bad routine over and over. This is why victims need to think and act out of the box to perform troubleshooting in such a scenario. The tips below address this jeopardy and will help remove ads by OptiBuy from an infected Mac.
