The sudden appearance of AddUpgrade in Mac Applications lists makes affected users believe that it is a virus.

AddUpgrade Mac App – Is It Dangerous?

AddUpgrade is a strange program that can appear in your Mac Application list without your knowledge. The undesired program is known to affect Mac operating systems with the help of other potentially unwanted programs like Search Baron and Solo Process. Another way for AddUpgrade to trick you into installing it on your Mac is via shady websites that host scam messages. The messages may sound scary by stating that your Mac is infected with viruses or informative by notifying you that your Flash Player needs an update.

To prevent falling victim to scam messages and bogus software packages, you should practice caution. Always download apps from trusted sources and read carefully all details mentioned in the EULA and all other steps in apps’ installers. In addition, look for the Advanced/Custom installation approach so that you can reveal the information there and eventually prevent installing PUPs like AddUpgrade. As regards annoying browser redirects that open bogus websites in the browser, try to spot the scam by checking whether the domain is legit or not, secured or not. If you have any doubt, better close the whole browser and scan the system for any present undesired/harmful files.

The moment AddUpgrade starts on your Mac, it becomes able to access the settings of installed browsers and alter some main preferences. As a result, you may find out that your homepage, new tab page, and default search engine are set to display a deceptive search engine or configured to redirect you to Yahoo/Bing search.

Unfortunately, there are many similar undesired apps that affect Macs in the very same way. Examples of such apps are ContentStyles, Receiver Helper and ContentBenefits.

Yet another issue that occurs after an unnoticed installation of undesired app like AddUpgrade is data harvest. Eventually, the following details may be collected and transferred to remote servers:

  • Visited URLs and websites
  • Browser’s home page
  • Search queries
  • Search queries on the visited web pages
  • Type of used browser
  • Operating system type
  • Internet protocol (IP) address
  • Geographic location
  • The domain name of current Internet service provider (ISP)
  • Diagnostic information which describes how their Services are operating on the system

Data records are likely to be used for the configuration of aggressive advertising campaigns that flood the affected browser with lots of annoying advertisements (pop-ups, pop-unders, banners, in-text links, redirects, images, etc.)

The ads generated by the so-called AddUpgrade virus on Mac may be related to suspicious or even hacked web pages. In the event that you load such a page in your browser, you may let it trigger an unnoticed download process of some kind of malicious software on your Mac.

Security experts advise affected users to remove AddUpgrade and associated files from their affected Macs as soon as they detect any of the described issues.
