Written by Tomas Meskauskas on (updated)
What is Simple Dark Theme?
While inspecting the Simple Dark Theme browser extension, we noticed that it displays intrusive advertisements. Apps that display ads are categorized as adware. Additionally, we found that Simple Dark Theme can read and change data on visited pages.
It is recommended not to trust advertising-supported apps (especially when they are promoted using deceptive methods).
Simple Dark Theme in detail
Simple Dark Theme is promoted as a tool that creates a dark theme for any website. However, it shows annoying ads that can lead to shady websites. Ads displayed by adware often promote technical support scams, phishing pages, questionable applications, etc. Sometimes, they can cause unexpected downloads and installations.
Also, Simple Dark Theme can read and change data on websites. It may be tracking users (collecting browsing data). Its developers may misuse the obtained information for marketing purposes, sell it to third parties, or monetize it in other ways. Thus, having Simple Dark Theme added to a web browser can lead to issues related to online privacy.
| Name | Ads by Simple Dark Theme |
| Threat Type | Adware |
| Symptoms | Your computer becomes slower than normal, you see unwanted pop-up ads, you are redirected to dubious websites. |
| Distribution methods | Deceptive pop-up ads, free software installers (bundling), fake Flash Player installers, torrent file downloads. |
| Damage | Internet browser tracking (potential privacy issues), display of unwanted ads, redirects to dubious websites, loss of private information. |
| Malware Removal (Windows) | To eliminate possible malware infections, scan your computer with legitimate antivirus software. Our security researchers recommend using Combo Cleaner. |
More about adware
In some cases, adware can hijack a web browser (operate as a browser hijacker). It can change the web browser's settings to promote shady (or fake) search engines. It is worth mentioning that browser-hijacking apps usually do not allow users to remove their search engines from the settings while they are added to browsers.
More examples of apps that display ads are WebSurf Guard, Video Player Pro, and Tab Session.
How did adware install on my computer?
Our team discovered Simple Dark Theme browser extension on a deceptive website suggesting that a free extension might be required. It got added to a browser after following the steps on that page. Simple Dark Theme also has its "official" website.
Also, adware often gets installed via shady advertisements and software bundles (mostly freeware installers). Installers containing adware have "Advanced", "Manual", "Custom", or similar settings (or ticked checkboxes).
Users install adware (or other unwanted apps) alongside other software when they finish installations without changing those settings (deselecting optional installations).
How to avoid installation of unwanted applications?
Download applications and files from trustworthy sources such as official websites and verified stores. Do not download them from shady websites, third-party downloaders, P2P networks, etc. Check downloaders and installers for unwanted apps and deselect them before downloading and installing programs.
Do not trust advertisements on questionable websites or allow such pages to show notifications. If your computer is already infected with rogue applications, we recommend running a scan with Combo Cleaner Antivirus for Windows to automatically eliminate them.
