TabNav is potential malware that collects a wide range of information and displays advertisements on the websites that you visit. The ad-supported program installs a Layered Service Provider that is able to observe and manipulate all the network data that you transmit and receive on your computer. This ability allows the program to access user browsing data, such as activities, bookmarks, and browser history. Furthermore, TabNav also installs a root certificate into machines running the Windows operating system called appimaker. The appimaker root certificate allows the adware to access secure socket layered (SSL) traffic so that it will be able to inject advertisements into encrypted online connections. It also gives the adware the ability to see all of the data you transmit over an encrypted SSL connection including credentials you use to log into your bank account, social media account, email, and more.
TabNav may be easy to notice while browsing online because of how aggressive it is. You may notice warning alert messages stating that there are certificate errors. For example, Microsoft Internet Explorer may display errors such as:
Content was blocked because it was not signed by a valid security certificate.
For more information see “About Certificate Errors” in Internet Explorer Help.
There is a problem with this website’s security certificate.
The security certificate presented by this website was not issued by a trusted certificate authority.
Security certificate problems may indicate an attempt to fool you or intercept any data you send to the server.
Google Chrome might display a Net::ERR_CERT_COMMON_NAME_INVALID error message that says “Your connection is not private.”
TabNav adware is usually contracted without user knowledge alongside free downloadable content from a variety of locations on the web. Free downloadable content includes freeware, shareware, torrents, email attachments, and more.
Users who wish to install freeware may be given a “custom installation” option to accept or decline an offer to install TabNav adware and similar products during the installation; However, the user request to decline the adware from installing can be ignored by the program or presented in a confusing manner.
In some cases, TabNav and other unwanted programs are deceptively promoted through questionable advertisements. These advertisements may be dishonest, misleading, and cause the program to automatically download and install once clicked on.
