Openthis.site is a cheesy New Year postcard site that harvests a variety of personal information

Openthis.site

Openthis.site is a website that users may encounter when browsing the internet on Google Chrome, Safari, Internet Explorer, or Mozilla Firefox. Once entered, users will be offered to make an allegedly free postcard that they can then share with others – all they need to do is enter their name. However, looking at the Openthis.site more closely, it becomes evident that the developers are ready to steal the information provided by you and even share it with third-parties.

Users who encounter dodgy sites like Openthis.site might also be infected with adware[1] – ad-supported software which, on itself, is usually not dangerous. However, through to tunnels of redirects that adware brings when browsing the internet, might lead users to scam, phishing, and even malware-laden websites. Therefore, Openthis.site removal from your browser might require a full system scan with anti-malware software.

Name Openthis.site
Type Adware 
Infiltration  Software bundles, ads, third-party sites 
Symptoms  Redirects, ads, sponsored links, and other suspicious browser behavior
Risks  Installation of other unwanted programs, malware infections, sensitive data loss, money loss
Termination  If your machine is infected with adware, scan it with security software like Reimage or make use of our manual removal guide below 

Adware programs usually get installed along with freeware or shareware applications downloaded from third-party websites. For that reason, users are unaware where the suspicious redirects, pop-ups, ad banners, deals, offers, coupons, sponsored links, and other intrusive content is coming from. This is how most of the users land on Openthis.site.

Openthis.site analysis on Hybrid Analysis[2] service showed that the domain has a threat score of 46/100, as it contacts several malicious URLs. This suspicious network traffic might lead to compromised websites of those specially crafted by hackers. In some cases, users might be affected by software vulnerabilities if their applications and the OS are not updated. In such a case, a single Openthis.site redirect or background traffic might download and install computer virus automatically, without any user interaction.

Another reason to avoid Openthis.site is its extensive information tracking. As it turns out, website developers are gathering a variety of data related to users who visit it with the help of tracking technologies like Cookies:

  • IP address;
  • Browser type and version;
  • Visited sites;
  • Unique device identifiers;
  • Other diagnostic data.

However, the statement on Openthis.site's Privacy Policy that even personal information might be gathered:[3]

While using our Service, we may ask you to provide us with certain personally identifiable information that can be used to contact or identify you (“Personal Data”). Personally identifiable information may include, but is not limited to:

  • First name and last name
  • Cookies and Usage Data

Thus, never provide any information to these people, as you will never know where it might end up – it might even get stolen by cybercriminals who commit online fraud.

To remove Openthis.site virus from your computer, scan it with reputable security software (Reimage or other) or terminated potentially unwanted programs manually – we provide detailed instructions below.

Openthis.site is a domain that users might encounter when their machines are infected with adware

PUPs often travel within software bundles 

Most of the time, users are surprised that their computers are affected by adware, as they are unaware of how the pesky program got in. This is usually because PUPs are included in a single software package downloaded from third-party sites. Some of these websites have implemented security measures to ensure that malware is hosted there. However, some sites are simply less secure, and you might even download a Trojan onto your machine, and it might result in more infections.

Therefore, always pick at least known sites for your freeware downloads. Nevertheless, always be aware that bundled software might also include adware and other potentially unwanted programs that, while not malicious, might expose you to online threats. Additionally, you should always pay attention to the installation process – do not skip steps, read the small print, untick pre-ticked boxes and always opt for Advanced/Custom settings instead of Recommended/Quick ones, as it is sometimes the only way to see the full list of apps which would be installed otherwise.

Remove redirects to Openthis.site and other suspicious sites

You can remove Openthis.site virus in two different ways: either by scanning your device with security software or by checking our elimination guide below. While both methods can result in the same outcome, the former is much quicker and more effective in most of the cases. Besides, ant-malware software is a necessity when it comes to computer security, so every person who browsers the internet should have one installed.

Openthis.site ads
Never click on the Openthis.site ads, as they might be unsafe

Once you complete Openthis.site removal, you should also reset each of the installed browsers. Adware often changes the settings of your browsers, so redirects and other suspicious activities might continue even after you uninstall all the potentially unwanted programs from your machine.

You can remove virus damage automatically with a help of one of these programs: Reimage, SpyHunter 5Combo Cleaner, Malwarebytes. We recommend these applications because they detect potentially unwanted programs and viruses with all their files and registry entries that are related to them.
