Newtab browser hijacker ads: what it is and how to remove it

Newtab is a potentially unwanted application that modifies browser settings without explicit user consent. It redirects users to a fake search engine called fxsmash.xyz and changes the homepage and new tab page to this suspicious domain. The hijacker was discovered in 2021 and reportedly affects Microsoft Edge, though other browsers may also be vulnerable.

When installed, all web searches and new tab navigation are redirected through fxsmash.xyz, which displays search results filled with commercial advertising and redirects to suspicious websites. The developers profit by hijacking traffic and promoting affiliated websites that may contain malware, scams, or other unwanted content.

Newtab typically enters systems bundled with free software downloaded from untrusted sources. Users often install it inadvertently during freeware setup by clicking 'Recommended' or 'Quick' installation options that automatically install additional programs. Deceptive pop-up advertisements, fake Flash Player installers, and software bundles from third-party download websites are common distribution methods.

The hijacker may also be installed through compromised websites offering false security warnings or fake browser update prompts. Users who don't carefully review installation steps or who use custom installation settings to uncheck unwanted programs are more likely to avoid this infection.

Infected users experience constant redirects to fxsmash.xyz and related suspicious websites, potentially exposing them to scams, phishing attacks, tech support scams, gambling sites, and malware. The hijacker collects browsing-related information including search queries, visited websites, location data, and IP addresses, violating user privacy.

Redirects may lead to pages hosting malware that could result in additional infections or data theft. Performance issues including slower browsing, frequent pop-ups, and browser freezing are common complaints. The collected data may be sold to third parties or used for targeted advertising campaigns that exploit user behavior patterns.

While Newtab itself doesn't directly damage system files like ransomware, it significantly compromises computer security and performance. The constant redirects may expose your system to malware-laden websites, potentially resulting in serious infections. Unauthorized collection of personal browsing data creates privacy risks.

Computer performance noticeably degrades due to unwanted background processes, excessive pop-ups, and redirects. System resources are consumed by the hijacker's operations, causing slower speeds and occasional freezes. Additionally, exposure to malicious websites and scam content through redirects increases the likelihood of downloading additional malware or losing money through online fraud schemes.

The easiest and most reliable method is using anti-malware software to scan and remove the infection automatically. Download reputable security software on a clean device if possible, then perform a full system scan on the infected computer. The malware removal tool will identify and delete files associated with Newtab and restore proper system function.

After automatic removal, manually reset your browser settings to defaults by removing unknown extensions, clearing cookies and browsing data, and checking homepage and new tab settings. Verify that fxsmash.xyz no longer appears as your homepage or search engine. A system optimization tool can repair any remaining damage from the hijacker's modifications.

Manual removal is possible but complicated and error-prone for inexperienced users. You would need to uninstall suspicious programs through Control Panel, identify and remove malicious browser extensions and add-ons, modify Windows registry entries, and reset browser settings individually for each browser.

Missing even one file or registry entry allows the hijacker to reinstall itself and continue hijacking your browser. Incorrectly deleting legitimate system files during manual removal can seriously damage your operating system. Professional anti-malware tools are specifically designed to handle this task safely and completely, making automatic removal the strongly recommended approach for most users.

While Newtab primarily collects non-personal browsing data like search queries, visited websites, and IP addresses, the privacy risk is still significant. However, the hijacker itself doesn't directly capture passwords or login credentials like some advanced malware does.

The real danger comes from the redirects to suspicious websites through fxsmash.xyz, which may host phishing pages designed to steal passwords or trick you into entering sensitive information.

If you visit banking or email websites after being redirected through malicious sites, attackers may have manipulated what you see on your screen using remote access tools, potentially capturing your login attempts. Always ensure you're on legitimate website URLs before entering sensitive information.

Download software only from official websites and trusted distributors, never from random third-party download sites or peer-to-peer networks where PUPs are commonly distributed. Always choose Custom or Advanced installation options to review all programs included in software bundles and uncheck unwanted additions.

Be skeptical of software update pop-ups that appear while browsing websites; instead, visit official software websites to check for updates directly. Keep your operating system and all software fully patched to close security vulnerabilities.

Maintain active, updated anti-malware software to detect and block unwanted installations before they occur. Avoid clicking suspicious advertisements and links from untrusted sources, and use ad-blocking extensions in your browser to reduce exposure to deceptive ads.

After removing Newtab with anti-malware software, manually reset each affected browser to factory defaults. In most browsers, this option appears in Settings under Reset or Advanced. Clearing browsing history, cookies, cached files, and site data helps remove any hijacker remnants.

Remove all unfamiliar extensions, add-ons, toolbars, and plug-ins, keeping only those you actively use and trust. Check that your homepage, new tab page, and search engine are set to your preferred choices, not fxsmash.xyz or other suspicious domains.

Import bookmarks from backups if available, or recreate important bookmarks manually. Using a system optimization tool helps repair registry changes and corrupted system files that the hijacker may have modified during installation.

Fortect scans Windows for malware and unwanted programs and repairs the system files and settings they change, and its free scan shows what it finds on your PC before you decide anything.

For Newtab browser hijacker, follow the plan above as well: the browser steps take back permissions and settings that no scanner treats as a threat, and uninstalling the program that brought it removes the source.

Run Microsoft Defender's full scan and, if anything was found, its offline scan as a second opinion. If the symptoms are gone after the plan and both scans are clean, there is nothing more to do.
