What is Pop-up ads?

Pop up virus is a term used to describe malware helping advertisers generate income from numerous ads

Pop up virusPop up virus is a form of advertisement that in some cases might be dangerous for end users. For that reason, users need to make sure that they do not interact with malicious content

Pop up virus is the term used to describe a pop-up window that displays advertisements on websites that users visit. Their primary purpose is to persuade users into visiting specific sites or purchasing particular goods. While it can be an excellent method for website authors to monetize their website content, it is a nuisance for the end-users.

Such a virus might also be hiding on sites that usually do not prompt such behavior – and this is when adware is involved. Ad-supported programs are typically downloaded unintentionally while installing freeware/shareware or when users are lured by the app's certain functionalities, for example, driver updating. Some of such apps, especially the latter type, might be difficult to associate with the intrusive ads showing up on all the sites, so users often struggle to find the source and stop these activities.

Name Pop up virus

Symptoms If you see an ad on a website that you visit, it does not mean you are infected with a computer virus, and it just means that the ad is embedded in the site. However, if you see intrusive ads an most of the websites you visit, along with redirects and browser changes, you should check your computer for adware

Pop-up ad advertising form was invented in the 1990s by Ethan Zuckerman[1], who later apologized for laying the ground for one of today's biggest Internet nuisances.

Some ads of this type can seem exciting and useful; however, they can also be highly dangerous and infect the computer system with malware[2] as soon as the victim clicks on the ad. In the majority of cases, annoying popups bother computer users that unwillingly install adware programs. One of the most efficient ways to cease the emergence of such commercial offers is to scan the PC with ReimageIntego or another virus remover.

The alerts containing some promotional content are typically opened in individual browser windows that appear on top of the active browser window or under it (these are called pop-under ads). The described advertising form was eventually adapted and used across various platforms, including Windows, Mac OS, and Android[3]. Nowadays, these adverts can appear not only on computer screens but on smartphones as well, so make sure you remove the virus from every device you use.

Pop-up virusPop-up virus is malware that users encounter on a variety of websites and are usually caused by adware, tech support scam malware or even ransomware. If bothersome advertisements keep appearing on your screen, you need to use a powerful anti-malware scanner to identify the infection and remove it from your PC.

Frequent appearance of ads might indicate adware infection

If you have been bothered by unwanted ads, you should know that your computer is infected. Typically, redirects and kinds of ads appear due to adware, browser hijackers, and similar PUPs, for example:

As soon as such a program enters your computer, it hijacks every web browser (Internet Explorer, Google Chrome, Mozilla Firefox, Safari, Opera, etc.). After doing so, it starts tracking you to get more information about your browsing habits.

To do so, programs that hide behind unwanted ads employ tracking technologies, including cookies and web beacons. They store information about the victim's browsing history, the list of search queries, frequently visited websites, ads and URLs clicked, time spent on particular sites, products viewed, and even IP addresses.

The majority of ad-supported programs promise to collect only personally non-identifiable data, although some pieces of data they collect (such as search queries) can contain personally identifiable information (PII). Some adware programs clearly disclose such fact in their Privacy Policy documents. For example, a popular browser hijacker zzz3.club, states the following:[4]

QxSearch may collect two types of information: 1) Personal Information, and 2(Anonymous Information. Personal Information means information that may directly or indirectly identify you, such as your name, address, email address, and telephone number. <…>

These potentially unwanted programs also claim to be collecting PII, but only “in case the user willingly provides it.” Such information is valuable and can be easily misused. The main reason to collect such data is to use it for market research and customization of ads.

You need to remove this related software to get rid of fake pop up ads on your web browser. However, sometimes it takes more than that because some of the PUP variants tend to change proxy settings and add wpad.dat files to keep serving sponsored content on the victim's computer.

Reasons why you might be seeing popups

Pop ups caused by adware

Annoying commercial offers appearing in new browser windows are most frequently sent by ad-supported programs that usually get into the computer system alongside other free software that the user willingly installs. However, such software bundles tend not to disclose the presence of additional software in a direct way and can install adware.

Agreements to install such programs typically hide in Default/Standard settings which look trustworthy for many people. Once installed, ad-supported parasites add specific browser extensions to all web browsers or even modify browser shortcuts to serve ads via them. Some adware programs are easy to remove, and other viruses tend to root deeply in the system. Currently, the most prevalent adware programs that keep bothering computer users are:

Recently, many users started complaining about annoying Russian ads appearing on websites that target the English-speaking audience. In such a case, it is obvious that such ads are bad and they do not originate from websites that the user visits, however, it can be harder to understand when ads caused by adware are provided in victim's native language or English.

To block annoying advertisements, usually, it is enough to run a system scan with anti-malware software like ReimageIntego. Most of the ad-supported programs can be deleted manually quite easily as well. However, some adware programs come in a bundle with browser hijackers, and in such situations, we usually advise choosing an automatic spyware removal option to save time.

Pop ups related to tech support scams

Tech support scammers have also adopted a new technique to swindle money from unsuspecting victims by using pop up virus. Although earlier they used to call victims themselves, now they decided to upgrade their tricks and use malware to convince computer users to call them. On top of that, scammers continuously create new phishing websites[5] and make them look like Microsoft's support page just to trick the victim into calling them.

Tech support scams aim to convey a sense of urgency by opening new browser windows and displaying ads that suggest calling “certified Microsoft technicians” as soon as possible due to bogus reasons such as “suspicious activity on the computer was detected” or “Windows detected ZEUS virus” and similar. An example of such a scam usually contains the following text:

*******************************************************
RDN/YahLover.worm!055BCCAC9FEC infection
*******************************************************
Windows Defender Alert: Zeus Virus Detected In Your Computer !!
Please Do Not Shut Down or Reset Your Computer.

The following data will be compromised if you continue:
1. Passwords
2. Browser History
3. Credit Card Information
4. Local Hard Disk Files.

The victim can receive these notifications if associated adware is installed on the system, or simply after clicking on a fraudulent link while scrolling through insecure web pages. The described malware can infect both Windows, Mac, and Android OS.

Pop up virus caused by ransomware

Some ransomware viruses (especially in the past) display a full-screen program window that blocks access to the computer. Additionally, there are ransomware viruses that employ victim's web browsers to display numerous notifications asking to pay a ransom to regain access to the PC.

One of the most prevalent examples is FBI ransomware, which primarily targets Mac OS, while there are versions for Windows and Android users as well. Such viruses typically prevent the user from closing annoying alerts that appear via a web browser.

Such ransomware viruses hardly ever encrypt files; therefore they are not as dangerous. However, described malware often accuses the victim of violating certain laws, for example:

  • Neglectful use of personal computer;
  • Attempts to access prohibited pornographic content;
  • Downloading and watching movies illegally, or similar.

The alleged copyright infringements allow crooks to ask for a “fine,” which, if paid on time, allegedly drops the charges. Described viruses usually demand a ransom paid via pre-paid cards such as MoneyPak or Ukash. In case your computer displays such notifications, use anti-malware for ad removal.

Different pop up ads can also threaten your privacy

No matter how harmless different ads seem, they can also threaten your privacy. This is done by asking people to provide their email addresses and similar information in exchange for discounts. Here we have to warn you that such pop up ads seem to be very useful and can be filled with huge discounts and price comparisons.

Probably the most dangerous pop-up virus suggests installing fake Java or Flash updates.[6] Such ads are usually filled with stolen logos (for example, Adobe or others), convincing pictures, and similar things. If you have any doubts, go to the official website of the program to see what updates you need. NEVER trust ads that came out of nowhere because most of them are used to infect people with malware or redirect them to malicious websites. Fake Flash Player updates are known to distribute the following malware:

Finally, the PUP, which launches pop-up ads, can easily slow down the work of your computer and can also make each of your web browsers run slower than ever. If you have already noticed intrusive ads on each of your web browsers without a break, you should waste no more time scanning your computer with a reputable anti-spyware, such as SpyHunter 5Combo Cleaner.

Ways to prevent ads from appearing

If you want to avoid pop-up ads, you need to stay away from adware triggering these ads. Typically, it infiltrates the system via the technique called “bundling.” This method facilitates developers of various freeware (download managers, PDF creators, video streaming software, video recording software, etc.) to earn money by promoting questionable browser add-ons, extensions, plugins, toolbars, and similar applications.

Some users believe that all ads can be blocked with programs like AdBlocker. However, in most cases, these annoying virtual parasites are sneaky enough to bypass AdBlocker restrictions. Here are a few tips:

  • Before installing a program, read what is said in its Privacy Policy and End User's License Agreement. If there is something about third party content, advertising, collecting your browsing information, etc., you should cancel the installation.
  • Opt for Custom or Advanced installation option to get ability to see optional components. Here, you should uncheck all pre-checked check marks that allow the installation of questionable browser add-ons, extensions, plugins and toolbars.
  • After selecting Custom or Advanced installation, you should also stay away from offers to change your start page or the default search engine.

How to remove pop up virus completely?

Once you notice pop-up ads, look for the responsible application. Check the system for some sponsored application that you installed to try to save some dollars while shopping online. Hardly ever such apps are useful. Despite their claims to improve your searches, they almost never deliver useful or money-saving deals.

Bear in mind modern programs are actively promoted on the Internet with the help of suspicious distribution techniques, so there is no surprise that your computer has been hijacked by one of them. Fortunately, it's not hard to get rid of annoying ads and related adware, especially if you have an effective virus remover on your computer.

Next, you should check your Internet Explorer, Firefox, Internet Explorer, Safari, or Chrome. For that, you just need to scan your computer with one of a malware elimination utility. You can also combine manual virus removal instructions. They will help you eliminate web scripts associated with the adware.

How to prevent from getting adware

Do not let government spy on you

The government has many issues in regards to tracking users' data and spying on citizens, so you should take this into consideration and learn more about shady information gathering practices. Avoid any unwanted government tracking or spying by going totally anonymous on the internet. 

You can choose a different location when you go online and access any material you want without particular content restrictions. You can easily enjoy internet connection without any risks of being hacked by using Private Internet Access VPN.

Control the information that can be accessed by government any other unwanted party and surf online without being spied on. Even if you are not involved in illegal activities or trust your selection of services, platforms, be suspicious for your own security and take precautionary measures by using the VPN service.

Backup files for the later use, in case of the malware attack

Computer users can suffer from data losses due to cyber infections or their own faulty doings. Ransomware can encrypt and hold files hostage, while unforeseen power cuts might cause a loss of important documents. If you have proper up-to-date backups, you can easily recover after such an incident and get back to work. It is also equally important to update backups on a regular basis so that the newest information remains intact – you can set this process to be performed automatically.

When you have the previous version of every important document or project you can avoid frustration and breakdowns. It comes in handy when malware strikes out of nowhere. Use Data Recovery Pro for the data restoration process.
