What is Adfoc.us virus?

Adfoc.us is a link shortening service that may bring malware to your computer

Adfoc.usAdfoc.us is a link shortening service that might be abused by cybercriminals to spread malicious links around the internet

Adfoc.us is a legitimate service that offers to shorten links for convenience the other purposes, and also claims that users can earn money by doing so. Link shortening services are extremely popular and benefit both parties – the providers can earn pay-per-click ad revenue, and the users can enjoy clutter-free links. However, despite all these benefits, there are certain security risks involved in using Adfoc.us links carelessly.

The safe usage of Adfoc.us highly depends on who is using the service, as cybercriminals can be one of them – they can create a site that hides a malicious code inside of it, and use the shortened link to disguise the origin of the site. These links can then be populated all across the internet by using social media platforms, adware,[1], and other methods. In other words, Adfoc.us platform can only be trusted when they are coming from somebody you know online, or if they are embedded on a trusted site. Otherwise, we do not recommend clicking on Adfoc.us links.

Besides the links that can lead to malware, the frequent appearance of Adfoc.us ads might also indicate adware infection, so it is important to check the system with a security program if suspicious browser behavior is observed.

Dangers Threat actors can use the service in order to disguise malicious links and populate them online by using different methods – the click may, in some cases, lead to the proliferation of malware. Additionally, the ad networks Adfoc.us uses might not always display secure content – gambling, “click allow to continue,” fake update and other prompts are common
Termination Adfoc.us ads can result in the installation of potentially unwanted programs and malware. To get rid of all the unwanted and malicious programs from your device, check the details below; a scan with anti-malware software is also recommended
Recovery In case your system got infected with adware or other malware, your system may start malfunctioning after its removal. In such a case, we suggest you scan your machine with ReimageIntego to fix virus damage

To use the Adfoc.us service, users are urged to register for an account, which asks for an e-mail, and a password – these details are collected by the site, according to its privacy policy. Without creating an account, users are unable to monetize on the shortened links, which can earn them as much as $22.50 per 1000 visits:

EARN CASH FOR YOUR VISITORS

Earn up to $22.50 per 1000 visits to your short URLs. Generate stats on-the-fly and break-down by countries, referrers, and specific dates. We payout users every month for earnings above $10.00.

While this may seem like a great deal, keep in mind that those who will use the Adfoc.us shortened links will be exposed to a large number of advertisements, and some of them might not be as secure. Quite often, various services employ not so secure advertisement networks that promote relatively unsafe content, such as gambling or suspicious online gaming sites with hidden fees.

In some cases, Adfoc.us might even show fraudulent notifications about outdated applications that seemingly need to be updated, or prompts that ask users to download browser extensions or potentially unwanted applications in order to proceed. In other words, an “Adfoc.us virus” term might very much be applicable in these cases.

We advise you not to download anything offered by the Adfoc.us ads and do not interact with buttons, as well as other content that is displayed before viewing the link, as you may end up installing useless software like scareware or potentially unwanted application like adware. In such a case, however, you will need to remove Adfoc.us apps or even malware from your machine.

Adfoc.us virusAdfoc.us is a site that offers users to shorten links and earn money, although this activity puts other users at risk

The easiest way to perform Adfoc.us removal is to scan the computer with a reputable anti-malware program – it will quickly determine whether you installed something unwanted or malicious on your device. If that is the case, experts[2] also recommend resetting Google Chrome, Mozilla Firefox, Safari, and all the other installed browsers to delete cookies[3] and other settings the PUP may have introduced. Finally, if you experience system crashes or errors, use ReimageIntego to fix virus-affected system files.

Watch out for malicious links and never install software that is promoted deceptively

It is not a secret that shortening link service earns money by showing users ads – it is a legitimate practice that is used by many high-profile websites. However, some ads might be just more dangerous than others, and it is important to take them into account. Some ads do not focus on regular advertising practices, such as promoting the service, application, or other products, but rather use deception or even fraud.

For example, quite often, users are presented with fake notifications that claim virus infections, accuse users of doing something illegal, their software needs to be updated, or insist that their machines have been blocked entirely.

As evident, all these claims are fake and should not be paid attention to. However, there are plenty of users that would believe the fake alerts, and that is precisely what malicious ad authors are counting for. Having that said, means that deliver such unfair advertisements should also be counted as malicious, and should never be trusted.

Quite often, link shortening services rely on shady advertising networks that pay more but put users' online safety at risk. Additionally, the adware may also bring users to these insecure sites that want to steal personal information, promote malicious apps, or make users pay for fake tech support services.[4]

To avoid this, users are advised to be very careful when browsing the web – never click on suspicious ads that try to intimidate with various claims, offer get-rich-fast-schemes, claim outdated software was detected, and similar fraudulent content.[5] As a countermeasure, however, an ad-blocking application can be employed – it would remove all the malicious ads from the doily web browsing routine. Additionally, security experts recommend installing a comprehensive security application and downloading software from trusted sources only, all while avoiding pirated and crack installers.

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.
