How to uninstall OptimalState adware from your operating system

What is OptimalState?

OptimalState is a rogue application classified as adware. It also possesses browser hijacker traits. This browser hijacker operates by making modifications to browser settings and promotes bogus search engines. On Safari browsers, it promotes d2sri.com, however, it might promote other search engines on different browsers.

Furthermore, most adware-type and browser hijackers can monitor users' browsing activity, which makes them a serious privacy concern. Due to the dubious methods used to proliferate OptimalState, it is classified as a Potentially Unwanted Application (PUA).

One of the distribution techniques employed for OptimalState is proliferation via fake Adobe Flash Player updates. Note that bogus software updaters/installers are used to spread PUAs, Trojans, ransomware and other malware.

Adware delivers pop-ups, banners, coupons, surveys and other intrusive advertisements. These significantly diminish the browsing experience, as they overlay web page content and reduce browsing speed. Additionally, once clicked, intrusive ads redirect to untrusted/malicious websites and some can even stealthily download/install software (e.g. PUAs).

Browser hijackers reassign the homepage, default search engine and new tab/window URLs to the addresses of fake search engines. Therefore, with this software installed, each new tab/window opened and search query typed into the URL bar redirects to the promoted address.

With OptimalState installed on Safari browsers, the aforementioned actions redirect to d2sri.com (it might also redirect to other web searchers). Bogus search engines are rarely able to generate search results, and so they tend to redirect to (or cause redirection chains ending with) Google, Yahoo, Bing and other genuine sites.

Browser hijackers can also undo any changes users attempt to make to their browsers and/or deny access to the browser settings outright. Therefore, recovering a hijacked browser is impossible without removing the software affecting it. As mentioned, most PUAs (including adware and browser hijackers) have data tracking capabilities.

They can monitor browsing activity (URLs visited, pages viewed, search queries typed, etc.) and gather personal information extracted from it (IP addresses, geolocations and other details). The gathered data is then shared with and/or sold to third parties (potentially, cyber criminals).

In summary, the presence of unwanted software on devices can lead to system infections, financial loss, serious privacy issues and even identity theft.

ElementaryUnit, ProductiveRotator, ExpandedCommand and RecordEnumerator are some examples of other adware-type apps. They may seem legitimate and harmless, and users are often enticed into download/installation and purchase with "useful" functionality, however, the features promised are seldom operational.

This is true of most PUAs. The only purpose of these unwanted applications is to generate revenue for the developers. Rather than delivering any real value, PUAs can run intrusive advertisement campaigns, hijack browsers, cause redirects and collect private data.

How did OptimalState install on my computer?

PUAs are often downloaded/installed together with other products. This deceptive marketing technique of pre-packing regular software with unwanted or malicious additions is called "bundling".

By rushing through download/installation of software (e.g. ignoring terms, skipping steps and sections, using "Quick/Express" settings, etc.) many users risk unintentionally allowing bundled content into their devices. Intrusive advertisements proliferate PUAs as well.

When clicked, the ads can execute scripts to download/install these applications without users' permission. Some PUAs have "official" download web pages from which they can be downloaded.

How to avoid installation of potentially unwanted applications

You are advised to research all software before download/installation. Use only official and verified download channels. Unofficial and free file-hosting websites, Peer-to-Peer sharing networks (BitTorrent, Gnutella, eMule), and other third party downloaders commonly offer harmful and bundled content, and are therefore untrusted and should be avoided.

When downloading/installing, read the terms, study all possible options, use the "Custom/Advanced" settings and opt-out of additional apps, tools, features, and so on. Intrusive advertisements typically seem legitimate, however, they can redirect to dubious and malicious sites (e.g. gambling, pornography, adult-dating, and many others).

If you encounter ads or redirects of this kind, inspect the system and remove all dubious applications and browser extensions/plug-ins immediately. If your computer is already infected with OptimalState, we recommend running a scan with Combo Cleaner Antivirus for macOS to automatically eliminate this adware.
