Adware Now Capable Of Hijacking Google Results

How Adware Alters Your Browser View of Search Results

When you type a query into Google and hit Enter, you expect the list of links that Google actually delivers from its servers. In reality, a small, stealthy piece of code that lives on your machine can rearrange those links right before they hit your screen. The result? The same query may show a handful of unfamiliar sites that look like regular search results, only they are paid placements that your browser is tricked into showing.

Unlike traditional spyware that records keystrokes or captures credentials, this adware doesn’t reach back into Google’s servers. It intercepts the data stream locally, rewrites the HTML, and inserts its own advertisements. The user still receives the original search data from Google, but the page’s visual layout is hijacked. The user is unaware that the browser has been tampered with, and the change can persist across multiple sessions and even after a reboot, because the malicious script is set to run on every startup.

Early reports from SERoundtable highlighted a variant that was first spotted on the site webthiswebthat.com. The malware would load during the initial page render and replace a portion of the result list with sponsored links. Users reported that these new links appeared indistinguishable from legitimate Google results - same font, same spacing, identical result boxes - making it difficult to detect the intrusion at a glance.

One user, who identified himself as “Nick W,” explained the phenomenon on the SEW forums. He said the malware does not alter the server-side data but modifies what the browser displays. “They don’t actually manipulate the Google results, just what your browser shows you on the page,” he wrote. This subtlety is what makes detection challenging: the network traffic to Google remains normal, while the visual output is altered.

Another common scenario involves adware that redirects you to a separate search engine - such as MySearch - once you land on the first Google results page. That type of hijack rewrites the browser’s homepage or default search provider. The newer variant, however, preserves the Google domain but injects its own adverts into the result list. The injected links often lead to affiliate sites or malicious landing pages that attempt to harvest credentials or serve malware.

Adware that tampers with search results is especially dangerous because it exploits a user’s trust in search engines. Search engines are the primary gateway to information on the web. By piggybacking on this trust, the adware can profit from every click that users think they are making on legitimate results. Even if a user notices a few suspicious links, the overall experience feels normal enough that many will ignore the anomaly.

For security researchers, the challenge is twofold: first, to identify the signature of the injected code; second, to understand how the adware survives removal attempts. Several reports indicate that once a system is cleaned, the malware may re‑install itself through an infected startup script or a browser extension that persists after a full uninstall. This persistence mechanism is what turns a one‑off infection into an ongoing nuisance.

Overall, the rise of adware that hijacks search results signals a new frontier in digital advertising fraud. Traditional ad blocking tools that focus on blocking external scripts may miss these local manipulations. Users and IT professionals alike must stay vigilant for subtle changes in their search experience, as the threat continues to evolve.

Cleaning Your System and Preventing Future Hijacks

When a user suspects that their search results have been tampered with, the first step is to confirm the infection. A quick way is to open a new private or incognito window and perform the same query. If the results appear normal, the problem is likely local to the main browser profile. If the same altered list appears in private mode, the issue might be network‑level, such as a compromised router or DNS hijack.

Assuming the infection is local, the next move is to run a reputable anti‑malware scanner. While many users rely on a single tool, combining two or more scanners increases the chance of catching all remnants. The following utilities have a strong track record against adware:

• Spybot – Search & Destroy – offers comprehensive scans for adware, spyware, and keyloggers.
• BHOdemon – specializes in removing malicious Browser Helper Objects in Internet Explorer and similar extensions.
• Spyware Blaster 3.1 – performs deep system scans and cleans up hidden threats.
• AdAware – effective at detecting and eliminating adware that modifies web pages.
• Spy Sweeper – claims to remove a wide range of malware in a single pass.

  Begin with a full system scan using Spybot, then run a second scan with Spyware Blaster to verify that no threats were missed. After each scan, review the list of detected items and manually delete any that remain. Do not rely solely on the scanner’s automatic removal if it flags an item as “unknown” or “safe.” Always double‑check before deletion.

  After removing the identified threats, reset your browser to its default state. In most browsers, this involves deleting or disabling extensions, clearing the cache, and resetting settings to default. For Chrome, navigate to chrome://settings/resetProfileSettings. For Firefox, use about:preferences#privacy to clear data. Resetting eliminates any hidden scripts that may have been installed as extensions or add‑ons.

  Next, examine the startup items that run when Windows boots. Open the Task Manager (Ctrl+Shift+Esc) and look under the Startup tab. Disable any unfamiliar entries. On Windows 10 and newer, the Services console (services.msc) also hosts many malware components. Search for services with names that contain “ad,” “search,” or “tool.” Stop and set them to “Manual” or “Disabled.”

  It is also wise to check the system’s hosts file located at C:\Windows\System32\drivers\etc\hosts. Malware sometimes redirects DNS queries by inserting entries that point search terms to malicious IPs. The file should normally contain only a few lines, primarily the loopback address. If you see additional entries, delete them carefully.

  While these steps address the immediate infection, prevention requires ongoing vigilance. Keep your operating system, browser, and all extensions updated to close known vulnerabilities. Install a reputable firewall or security suite that monitors outgoing traffic. Consider using an ad blocker that also blocks local scripts, such as uBlock Origin with the “Local Resource Blocking” feature enabled. Finally, be cautious about downloading software from unofficial sources or clicking on suspicious emails; many adware variants are bundled with free downloads.

  In the event that the adware re‑appears after a reboot, revisit the startup items and registry keys. Some variants embed themselves in the registry under HKLM\Software\Microsoft\Windows\CurrentVersion\Run or HKCU\Software\Microsoft\Windows\CurrentVersion\Run. Remove any keys that reference the known adware executables.

  For those who need to ensure the integrity of their search results on a larger scale - such as in a corporate environment - implementing a content filtering solution that checks web page integrity can be beneficial. Such systems can flag pages that deviate from the expected layout or include unexpected scripts, alerting administrators before users are impacted.
