Removal instructions for Cyber Shield adware and the ads it displays

Also Known As: Ads by Cyber Shield
Type: Adware
Damage level: Medium

What is Cyber Shield?

While inspecting deceptive websites, we found a scam page stating that there is an "Important Update for Chrome" - from it, we downloaded and thus discovered the Cyber Shield browser extension. This piece of software claims to be a tool that improves online personal data security. However, our analysis revealed that Cyber Shield operates as adware instead.

Cyber Shield adware overview

Adware stands for advertising-supported software. It delivers intrusive ad campaigns, i.e., displays advertisements on various interfaces. These adverts promote online scams, unreliable/dangerous sites and software, and even malware. Some intrusive ads are capable of performing stealthy downloads/installations upon being clicked.

Note that any legitimate products/services encountered through these advertisements are unlikely to be endorsed by their developers/creators. Scammers often abuse affiliate programs of genuine content in order to obtain illegitimate commissions for the endorsement.

It must be mentioned that advertising-supported software might not displays adverts if certain conditions are unsuitable, e.g., incompatible browser/system specs, particular websites are not visited, etc. However, even if Cyber Shield does not deliver ads - its presence on a system threatens device/user safety.

Furthermore, this browser extension spies on users' browsing activity. Data of interest may include: visited URLs, viewed webpages, searched queries, usernames/passwords, personally identifiable details, finance-related data, etc. The collected information can be monetized via sale to third-parties or otherwise abused for profit.

To summarize, the presence of software like Cyber Shield on devices - can lead to system infections, severe privacy issues, financial losses, and identity theft.

Adware examples

We have inspected thousands of adware samples; Ads Blocker ProWatch MoviesWebsites DrawerFiles Converter Free Online - are merely some of our newest finds.

Advertising-supported software typically appears legitimate and offers "useful" functionalities. However, these features seldom work as promised, and in most cases - they are utterly nonoperational. Therefore, not only is this software useless, but it also endangers device integrity and user privacy.

How did Cyber Shield install on my computer?

We acquired Cyber Shield from a scam website. In addition to deceptive sites, adware can also have "official" promotional pages. Most users enter webpages of this kind via redirects caused by misspelled URLs, sites using rogue advertising networks, spam browser notifications, intrusive ads, or installed adware (with browser force-opening abilities).

Furthermore, intrusive advertisements proliferate advertising-supported software. When clicked on, some of the adverts can execute scripts to perform downloads/installations without user consent.

"Bundling" - packing regular program installers with unwanted/malicious supplements - is used to distribute adware. Downloading from dubious sources (e.g., freeware and third-party websites, P2P sharing networks, etc.) and rushing installation (e.g., using "Easy/Quick" settings, etc.) - increase the risk of allowing bundled content into the device.

How to avoid installation of adware?

We strongly recommend researching software and downloading it from official/trustworthy channels. When installing, it is crucial to read terms, study possible options, use the "Custom/Advanced" settings, and opt-out of additional apps, extensions, tools, etc.

We advise being careful while browsing since fraudulent and malicious online content usually appears legitimate. For example, intrusive ads may look harmless yet redirect to highly questionable websites (e.g., gambling, pornography, adult-dating, etc.).

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