How to eliminate software that causes redirects to sunny-days.co

What kind of website is sunny-days.co?

Sunny-days.co is the address of a fake search engine that we discovered while investigating the Sunny Days browser hijacker. This extension is endorsed as a tool for changing browser wallpapers and allowing easy access to weather reports.

Sunny Days changes browser settings to promote (through redirects) the sunny-days.co webpage. The browser extension also spies on users' browsing activity.

Sunny Days browser hijacker overview

Browser-hijacking software alters browsers' homepages, default search engines, and new tabs/windows. Due to these modifications, users experience redirects to endorsed sites when they search the Web via the URL bar or open a new browser tab/window. Note that this software may utilize persistence-ensuring mechanisms to prevent users from recovering their browsers.

Sunny Days operates in the same manner and promotes sunny-days.co. Like most, this fake search engine cannot provide search results and lands on a genuine Internet search website. At the time of research, sunny-days.co led to the Bing search engine (bing.com). However, it might land elsewhere, as factors like user geolocation may impact redirects.

Furthermore, Sunny Days has data-tracking abilities. Browser hijackers typically target the following data: visited URLs, viewed pages, searched queries, Internet cookies, log-in credentials, personally identifiable details, finance-related information, and so on. The collected data can be monetized via sale to third-parties (potentially, cyber criminals).

In summary, software like Sunny Days can cause system infections, severe privacy issues, financial losses, and even identity theft.

Browser hijacker examples

Animal Lover Extension, My Search Newtab, Guardian Angel, and Web-Organize People Backgrounds are merely some examples of browser hijackers.

Software within this classification usually appears legitimate and offers various functionalities. However, these funds are typically fake and nonoperational, as they only serve as bait that deceives users into downloading/installing.

It must be stressed that even if a browser extension or an application works as advertised – that is not definitive proof of either legitimacy or safety.

How did Sunny Days install on my computer?

Sunny Days has an "official" promotional webpage. In addition to such sites, browser hijackers can be endorsed on scam pages. Most visitors enter these webpages via redirects caused by websites utilizing rogue advertising networks, intrusive ads, misspelled URLs, spam browser notifications, and installed adware.

Browser-hijacking software can also be bundled with ordinary software. Downloading from dubious channels (e.g., freeware and third-party sites, Peer-to-Peer sharing networks, etc.) and rushing through installations (e.g., ignoring terms, skipping sections, using "Easy/Quick" settings, etc.) – increase the risk of unintentionally allowing bundled content into the device.

Additionally, browser hijackers are spread by intrusive adverts. When clicked on, some of these advertisements can execute scripts to perform downloads/installations without user consent.

How to avoid installation of browser hijackers?

We recommend researching software and downloading only from official/trustworthy sources. Installation processes must be treated with caution, e.g., by reading terms, inspecting available options, using the "Custom" or "Advanced" settings, and opting out of all additional apps, extensions, tools, etc.

We also advise vigilance when browsing since fake and malicious online content usually appears legitimate. For example, while intrusive ads may look harmless – they redirect to unreliable and questionable websites (e.g., gambling, scam-promoting, pornography, etc.).

In case of continuous encounters with adverts/redirects of this kind, check the system and immediately remove all suspect applications and browser extensions/plug-ins. If your computer is already infected with Sunny Days, we recommend running a scan with Combo Cleaner Antivirus for Windows to automatically eliminate this browser hijacker.

Is visiting sunny-days.co a threat to my privacy?

To a certain extent, yes. Websites deemed as fake search engines (e.g., sunny-days.co, etc.) typically collect information about their visitors. The gathered data may then be sold to third-parties.

Therefore, it is paramount to eliminate browser hijackers thoroughly and all at once.
