What is Pronto App

Pronto App is software, advertised as a great tool to help you improve your Mac. In reality, this is a parasite from the PUA (potentially unwanted application) category. This app will spam you with all sorts of intrusive advertisements and pop-ups, which may lead to potentially dangerous third-party websites.

How it is distributed

This PUA is known to spread via freeware, software bundles, torrent files, email attachments, fake update messages, infected ads and links, etc. It’s very common for ‘optional’ programs to appear in an installer. It is highly recommended not to install them, since in most cases, the software in question turns out to be malware in disguise. When installing software, always opt for a custom/advanced process, so you have full control over what gets access to your Mac. If you don’t specifically opt out of the additional software’s installation, they will automatically get installed on your computer.

How it operates

Users report that the Pronto App is displaying various aggressive pop-ups, banners and ads, even if you have AdBlocker on your Mac. The parasite may also redirect you to shady sites. To ensure that you’ll click on them, the PUA will monitor your online activity and collect data like browser history and search queries. With this information, it will be able to provide targeted ads, which will be as attractive to you as possible. Even if you decide to ignore the ads, this won’t solve the problem. The parasite will just become more and more aggressive, causing your browser to crash and freeze on a regular basis. And let’s not forget the threat, which the third-party websites hold. You may think you’re clicking on a reliable ad, or getting redirected to a safe page, but in reality, this may be a trap set by the creators of Pronto App, aiming to steal sensitive information like credit card numbers, bank account credentials, etc. The shady redirections may even try to make you install more junk on your Mac. That being said, as soon as you notice the Pronto App on your PC, you need to immediately remove it, before it is able to cause damage.

Staying safe from Pronto App

Apart from having a reliable AV software installed on your Mac, there are other things you can do to ensure your device’s safety. We highly recommend you to:

• Pay close attention when you install third-party software, especially torrent files, so you don’t install shady additional applications that you don’t want. In most cases, that’s how malicious parasites are able to infect your computer;
• Read any Terms and Conditions you see, so you know exactly what you agree to. The last thing you want is to unknowingly give permission to a nasty virus to infiltrate your Mac;
• Follow links that lead to trustworthy sites only;
• It is best to visit only reliable and official websites. You never know what dangers might lurk behind an unfamiliar site;
• No matter how attractive an ad is, if you are not familiar with the website it redirects to, it might be best to steer clear of it and not click;
• Always check the sender’s email address before opening a message. If it states that it’s from an official company, compare the email with the one given in their official page. If there is no match, delete the message, since it most likely is fake and has malicious aims;
• Don’t open email attachments from unknown senders. More often than not, such files carry infections that can seriously damage your computer.
