'Calculator Tab' Can be a Devious Application That Hijacks Web Browser Functions

Calculator Tab is a browser extension that claims to offer a handy calculator widget. However, beneath its benign appearance lies a browser hijacker that manipulates browser settings to promote the fake search engine, searchfst.com.

How Calculator Tab Hijacks Your Browser

Calculator Tab alters your browser’s default search engine, homepage, and new tab settings to redirect you to searchfst.com. When users input a search query or open a new tab, they are led to this fake search engine, which doesn't generate its own search results. Instead, it redirects users to legitimate search engines like Bing, although this could change based on factors such as user location.

Persistence and Data Tracking

Browser hijackers like Calculator Tab often employ persistence techniques to prevent their removal. This includes blocking access to settings and reversing any changes made by the user. Additionally, these hijackers typically have data-tracking capabilities, collecting information such as visited URLs, search queries, internet cookies, personal identifiers, and even financial data. This sensitive information can be sold to third parties or exploited for profit, posing significant privacy and security risks.

Risks and Implications

The presence of software like Calculator Tab can lead to severe consequences, including system infections, privacy breaches, financial losses, and identity theft. Despite appearing legitimate and offering seemingly useful features, such extensions rarely function as promised, if at all. Even if they do work as advertised, it does not guarantee their safety or legitimacy.

How Does Calculator Tab Install on Your Computer?

Calculator Tab can be acquired from its official promotional webpage, but it’s also distributed through scam sites, intrusive advertisements, and bundled with other software. Common sources include freeware websites, P2P networks, and rogue advertising networks. Often, users inadvertently install such hijackers by using “Easy/Express” installation settings, which automatically include bundled content.

Intrusive Advertisements

Intrusive ads can execute scripts to download and install unwanted software without user consent. These ads often appear legitimate, but clicking on them can lead to the installation of browser hijackers like Calculator Tab.

Research and Caution

To avoid browser hijackers, always download software from official and verified sources. During installation, use the “Custom/Advanced” settings to review and opt out of any additional unwanted applications or extensions.

Careful Browsing

Be cautious while browsing the internet, as fake and harmful content often masquerades as legitimate. Intrusive advertisements, despite their harmless appearance, can redirect to malicious sites.

If you encounter persistent redirects or suspicious ads, inspect your system and remove any dubious apps and extensions immediately. If already infected with Calculator Tab, run a scan with an anti-malware tool to automatically eliminate the browser hijacker.

By staying vigilant and taking proactive measures, you can protect your browser and personal information from malicious extensions like Calculator Tab.
