This article provides comprehensive analysis of the Mac Cleanup Pro malware issue, including the infection’s behavioral quirks and ways to remove it from Mac.
What is the Mac Cleanup Pro virus?
One of the things the cyber world has in common with the world around us is that there are genuine entities and copycats that might be problematic to identify as such. In terms of Mac software, the niche of optimization and security apps is gaining traction these days, and so is the cluster of rogue programs that only pretend to be helpful. Mac Cleanup Pro falls under the scareware category because it mimics system tune-up features without actually doing anything the users will ever appreciate. It comes as a nifty-looking Mac utility that claims to be able to find common performance issues and easily repair them to boost the performance of the host machine. While the first impression about this application could be okay based on its GUI design and the speed at which it runs its scans, the tactic it employs ultimately proves this opinion wrong.
The Mac Cleanup Pro virus mostly arrives with bundles of freeware apps that aren’t necessarily junk but make the rounds as part of software packages. The fundamental issue with this distribution technique is that the “undercover” items accompanying the main one may be malicious, and the setup clients often don’t allow the users to get the big picture of what exactly is being installed as an extra. For instance, you may be happy to finally find some new free-of-charge media player on a software download portal you aren’t familiar with, but the joy vanishes once you realize that the default installation mode has pulled in Mac Cleanup Pro without letting you know. One more technique used to push this baddie resembles tech support scams, where a website suddenly pops up telling you that your MacBook Air/Pro or iMac is badly infested with threats and recommending you to downloading the “fix”, which is a rogue app in disguise.
Once inside a Mac, the fishy utility in question will instantly draw all of your attention by starting a spoof system scan. It supposedly checks the computer for redundant files, such as all forms of cache, duplicates, large objects, unused files, logs you no longer need, and the like. When through with the checkup, the pest displays a report where nearly all of the above areas will be flagged red due to the allegedly high improvement potential. It will purport to have detected hundreds of unnecessary objects which, if deleted, will free up gigabytes of disk space. Being able to release so much memory is certainly a tempting option, but the pitfall is that most of these issues are made-up to hoodwink you into proceeding to the next step. It boils down to upgrading your subscription – in other words, Mac Cleanup Pro will instruct you to purchase its licensed copy otherwise the problems cannot be addressed.
If you think you can simply disregard these scan reports and follow-up popup reminders about system slowdown and possibly even viruses, you might be missing the point. This scareware will be gradually escalating the pressure through deliberate Mac performance deterioration, more alerts, and browser-related brainwashing. Speaking of the latter, the infection is known to interfere with DNS settings and may add a potentially harmful extension to the victim’s default browser, whether it’s Safari, Chrome or Firefox on Mac. This way, it causes the web traffic to be forwarded to misleading sites that may say “Your Mac is infected with 3 viruses” or include similarly scary warnings. The goal is to make you download the “featured” tool, which is the malware under scrutiny. Consequently, the attack gets more obnoxious over time, and it won’t discontinue unless Mac Cleanup Pro is completely removed.
