How to remove DimMode adware from the operating system
Written by Tomas Meskauskas on (updated)
What kind of application is DimMode?
After testing the DimMode application, we learned that it provides no useful features and generates annoying advertisements. Additionally, it can read data on all visited websites. Thus, we classified DimMode as adware. It is worth mentioning that this app/browser extension is promoted via deceptive websites.
DimMode in detail
DimMode is described as an extension that provides a dark mode for simple websites. However, the purpose of this app is to show various advertisements (e.g., banners, pop-up ads, coupons). It is not safe to click on ads displayed by adware - they can open untrustworthy (potentially malicious websites).
Ads displayed by adware can open deceptive pages asking to provide personal information, instructing to call a fake technical support number, offering to download shady apps, etc. Sometimes, these ads can be designed to run certain scripts and cause unwanted downloads and installations.
| Name | Ads by DimMode |
| 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 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 DimMode
It is known that DimMode can read and change data on all visited web pages. Its developers may use this function to gather information information about users that may be later sold to third parties or used for other purposes. Thus, having DimMode can cause problems related to online privacy.
More adware examples are Reduce-Light, Movieholic, and Nino Colors.
How did adware install on my computer?
DimMode is promoted on a deceptive website claiming that a free extension might be required. It gets added to a web browser after following the instructions on that page. Also, this extension has an "official" website. In both cases, it is not mentioned (at least not clearly) that DimMode displays unwanted advertisements.
In other cases, apps of this type get installed via software bundles (installers containing additional apps), deceptive advertisements, or fake installers. When installers include adware or other unwanted apps, they have "Advanced", "Custom", or other settings. Adware installs after finishing installations without changing those settings.
How to avoid installation of unwanted applications?
Download applications from official pages (or stores). Do not use third-party downloaders (or stores), unofficial pages, P2P networks, and similar sources. Also, do not trust advertisements appearing on suspicious websites or allow such pages to show notifications. Clicking them (ads and notifications) can open malicious websites.
Always check downloaders/installers for optional downloads/installations and deselect unwanted ones. Usually, it can be achieved by changing the provided settings (e.g., "Custom", "Manual", "Advanced") or unticking checkboxes. If your computer is already infected with rogue applications, we recommend running a scan with Combo Cleaner Antivirus for Windows to automatically eliminate them.
