OperationReview adware in detail

OperationReview can show advertisements designed to open various pages that promote shady applications, phishing pages used to extract sensitive information, technical support scam sites, and even malicious sites. Moreover, OperationReview may show ads designed to run certain scripts and download or even install unwanted software.

It is strongly recommended not to click on ads shown by OperationReview. Another issue with apps like OperationReview is that they can be capable of accessing sensitive data. We found that some of these apps can read credit card details, passwords, and other personal information.

Adware in general

Advertising-supported applications generate annoying advertisements. In addition to showing ads, they can change the settings of web browsers (promote fake search engines by hijacking web browsers) and gather information. It is uncommon for adware like OperationReview to be downloaded and installed intentionally.

More adware examples are AnalyzerSystem, ComputingInvolve, and BridgePro.

How did OperationReview install on my computer?

Typically, users install adware by clicking deceptive advertisements or through fake installers downloaded from deceptive pages. Also, adware often gets installed via software bundles. Advertisements can download or install adware when designed to run certain scripts.

Downloaders/installers used to distribute adware have "Advanced", "Custom", or similar settings (or ticked checkboxes). Unwanted downloads/installations happen after downloading/installing programs without changing those settings.

How to avoid installation of unwanted applications?

Do not download software (or files) from unofficial pages, third-party downloaders, P2P networks, or other questionable sources. Use legitimate/official web pages and stores to download apps. Also, do not click on advertisements appearing on questionable pages (e.g., torrent sites, adult pages).

Deselect unwanted downloads and installations (by changing the available settings) before downloading and installing software. Never agree to receive notifications from suspicious websites. If your computer is already infected with OperationReview, we recommend running a scan with Combo Cleaner Antivirus for macOS to automatically eliminate this adware.
