How to eliminate JsTimer from a web browser
Written by Tomas Meskauskas on (updated)
What kind of extension is JsTimer?
JsTimer is presented as a simple timer extension for Chrome browsers. However, we found that it is distributed alongside other dubious extensions and apps. Also, it can read certain information. Therefore, we classified JsTimer as an unwanted extension. If this or any associated extension (like Funny Tool) is already present, users should remove it.
JsTimer in detail
We learned that JsTimer can read browsing history. By accessing browsing activity, JsTimer can track users' website visits, gather data about their online behavior, and potentially share this information with third parties. In addition to harvesting browsing history, JsTimer may collect other potentially sensitive data that might be misused for malicious purposes.
Moreover, this extension might redirect users to unwanted or malicious websites (e.g., phishing websites), which could be designed to steal more data, extract money, or infect devices with malware. Also, JsTimer may alter browser's settings, such as the homepage and default search engine, without user consent.
It is worth noting that once JsTimer is installed, it activates the "Managed by your organization" feature in Chrome browsers. Typically, this feature is used by companies and organizations to enforce specific policies. However, when misused by extensions like JsTimer, it can be exploited for harmful purposes.
Furthermore, JsTimer extension might degrade the web browser's performance, causing it to run slower or crash frequently. As we mentioned in the introduction, JsTimer is distributed alongside other unwanted extensions, including browser hijackers (e.g., QuickSearch). Those apps can also include adware and even more malicious software.
Therefore, having JsTimer added to a web browser can expose users to malicious content, privacy and security issues, and other problems. Users should avoid adding this extension to browsers and remove it if it is already present. Our removal guide for unwanted extensions can be found below.

How did unwanted software install on my computer?
It is common for untrustworthy extensions to be added via unofficial app stores or deceptive websites. P2P networks, third-party downloaders, misleading pop-ups and advertisements, and similar channels can also be used to distribute unwanted extensions and trick users into downloading them.
Another method to distribute unwanted apps and extensions is to bundle them with dubious and free software. During installations, users might not notice the included offers and agree to add/install unwanted apps or extensions. Usually, these offers are hidden in "Advanced", "Custom", or similar settings.
How to avoid installation of unwanted applications?
Always get extensions, apps, and software from official websites or reputable app stores. During installation, look for "Custom" or "Advanced" or similar settings and deselect any unwanted offers. Avoid clicking on suspicious links, pop-ups, or ads, and make sure your programs and operating system are kept up to date.
Additionally, regularly use a trusted antivirus program to scan your computer for threats. If your computer is already infected with rogue applications, we recommend running a scan with Combo Cleaner Antivirus for Windows to automatically eliminate them.
