Defpush is an Android notifications virus that hijacks web browser to display sponsored content 

Defpush.com notifications

Defpush.com is an advertising network misused by scammers to show notifications on Android.[1] While it can also display its pop-up ads on Windows OS devices, the Android operating system is infected even more frequently. The real reason why people are interrupted by aggressive notifications is the potentially unwanted program[2] hiding in their system. The unwanted application redirects users to defpush.com and 2-3 other questionable websites. While it is still unknown what is to blame for causing Defpush notifications on the screen, if you have recently installed some “helper”, optimization tool, or a similar program which is supposed to enhance the work of your device, check it with anti-spyware. Use Android virus removal guide to reset your device to its factory settings.

Distribution Software bundles, deceptive ads
main risks Once you allow push notifications, your browser is filled with dangerous content; you can be redirected to infected sites

The PUP has been associated with various commercial content delivered to victims while browsing the Internet. It is almost identical to other push notification viruses, such as Directlinkkpush.comExerciers.mobi, Worldnaturenet.xyzand many others that hijack systems to reroute victims to sponsored sites. Unfortunately, you can't block Defpush notifications with the help of popular ad blockers. As soon as the user allows them, the virus modifies the web browser to stay on the system for as long as possible.

Victims infected with Defpush.com Android virus should be careful when interacting with ads, as clicking on them can result in the installation of malware, useless extensions or optimization tools. This guarantees ad income for partners and boosts traffic to their websites, which artificially increases the rank of it. Nevertheless, if an advertisement redirects to a potentially malicious site, the user might accidentally get his/her computer infected with a Trojan horse,[3] ransomware, or other viruses.

You can find the commercial content displayed by Defpush virus is very tempting because it has also been set to spy on its victims to know more about their preferences and browsing habits. The adware can be set to track users' most visited sites, clicks, their location, IP address, geo-location, and any other information revealed during their searches. While adware[4] threats do not collect Personally identifiable information (PII), it can get access to your non-personal data and misuse it for marketing purposes.

A full system scan is required for the elimination of all cyber infections if you want to delete them for good, so make sure you take care of your PC's security by selecting a reputable anti-spyware and keeping it up-to-date.

In short, you should reset your device to factory settings to get rid of all PUPs causing issues on it.

Adware programs can be brought to the system by deceptive ads and free downloads 

Since there is an opportunity to get anything online, people tend to use p2p networks[5] or questionable sites as the source of desired software. However, security experts[6] advise avoiding services which offer to share and downloading various programs for free. What you should do is always opt for the reputable website or the official App Store when in need for something.

Also, choosing Advanced or Custom options during installations can be crucial for the security of your device since these settings allow you to de-select unwanted additional programs from the list. This way you make sure that the software you need gets installed on the device and nothing else. Make sure you never perform installations when the Quick/Recommended mode is on, otherwise, PUPs might be able to infiltrate your system unnoticed very easily.

Keep your software, programs and anti-malware tools up-to-date so no deceptive advertisement can trick you into purchasing anything useless. Various ads promote system optimization tools or display alerts about the poor security of your PC with the purpose of downloading their product onto your system. If you always pay attention to your online activity and be cautious while performing computing work, you can avoid cyber intruders in the future.
