How to eliminate the TopADSBlockSearch browser hijacker?
Written by Tomas Meskauskas on
What is TopADSBlockSearch?
TopADSBlockSearch is a rogue browser extension. It modifies browsers and promotes the topadsblock.com fake search engine; due to this - it is categorized as a browser hijacker. Furthermore, the questionable methods used to distribute browser hijackers also classify them as PUAs (Potentially Unwanted Applications).
TopADSBlockSearch browser hijacker in detail
Browser hijackers reassign browsers' tab/window, default search engine, and homepage URLs - to fake web searcher addresses (e.g., topadsblock.com). Hence, in the case of TopADSBlockSearch: new browser tabs/windows opened and search queries typed into the URL bar - redirect to topadsblock.com.
Illegitimate search engines usually cannot generate search results, so they redirect to genuine ones. Topadsblock.com is not an exception; it redirects either to the legitimate Yahoo (search.yahoo.com) or the fake searchlee.com search engines (possibly others). While searchlee.com can provide search results, they are inaccurate and may push untrustworthy/malicious sites and content.
Browser hijackers can revert user-made changes or restrict access to the browser settings outright. Therefore, recovering a browser is impossible without removing the software hijacking it.
TopADSBlockSearch likely spies on users' browsing activity. Most browser hijackers collect visited URLs, viewed pages, searched queries, IP addresses, personally identifiable details, etc. The gathered data is then shared with and/or sold to third-parties.
In summary, the presence of data-tracking software on devices can lead to serious privacy issues, financial losses, and even identity theft.

Browser hijackers in general
GameSearchTech, IncognitoSearchWeb, GetStreamSearch - are a couple examples of browser hijackers. They appear ordinary and offer functionalities, which they seldom have. In fact, the sole goal of PUAs is to generate revenue; hence, functionality and user safety are irrelevant. Unwanted apps are designed to hijack browsers, cause redirects, run intrusive ad campaigns (adware), and collect sensitive data.
How did TopADSBlockSearch install on my computer?
PUAs are proliferated using the "bundling" marketing method - packing programs with various additions. Rushed downloads/installations increase the risk of allowing bundled content into the device. Intrusive advertisements are employed to spread PUAs as well. Once clicked on, the ads can execute scripts to make stealthy downloads/installations. Some PUAs also have "official" download webpages.
How to avoid installation of potentially unwanted applications?
It is recommended to always research software and download it from official/verified sources. Untrustworthy download channels, e.g., unofficial and freeware sites, Peer-to-Peer sharing networks, etc. - often offer bundled and dangerous content.
When downloading/installing, it is advised to read terms, explore available options, use the "Custom/Advanced" settings, and opt-out from all supplements. Intrusive adverts appear legitimate, yet they redirect to highly questionable websites (e.g., gambling, pornography, adult-dating, and so forth).
In case of encounters with such ads and/or redirects, the system must be checked and all dubious applications and browser extensions/plug-ins detected - immediately removed from it. If your computer is already infected with TopADSBlockSearch, we recommend running a scan with Combo Cleaner Antivirus for Windows to automatically eliminate this browser hijacker.
