    What are Yontoo PageRage, Yontoo Layers Client and Yontoo Toolbar?

    Yontoo PageRage, Yontoo Layers Client and Yontoo Toolbar are adware that displays advertisements and hijacks your browsers. Although some adwares are not harmful, they are a nuisance due to constant pop-ups and ads. It is recommended that you remove these programs as some can be malicious.

    Yontoo PageRage, Yontoo Layers Client and Yontoo Toolbar installs itself, without the user's permission. Once installed, it displays various advertisements and tracks the user's surfing activity. It also redirects the user's search results to advertisement sites. In addition, this adware may also install other junk or unwanted programs onto the user's PC without the user's knowledge. The browser interface may also look different, as a result of this adware.

    It is highly recommended that you remove Yontoo PageRage, Yontoo Layers Client and Yontoo Toolbar from your computer.

    How was I infected?

    • Rogues can get on to computers without the user's consent through Drive-by downloads. When a user visits a compromised or infected website, the site immediately checks for any security vulnerabilities on the machine to inject the malicious code.
    • Peer-to-peer (P2P) programs such as utorrent are frequently used by hackers to distribute malware
    • Although the peer-to-peer programs are legitimate, the files shared are extremely dangerous. Hackers often use fake file names to trick users into downloading malware.
    • Hackers can also trick the user into downloading a file, saying it is a legitimate file needed to view a video or pictures.

    How can I prevent these infections?

    Now that your PC is clean, I recommend you to create a new System Restore point then purge the old ones after.

    For XP
    How to create a Restore Point in XP
    Delete all restore points except the most recent one

    For Vista
    Create a restore point
    Delete all but the most recent restore point

    For Windows 7
    Create a restore point
    Delete all but the most recent restore point - Click the Delete all but the most recent restore point link

    Keep your system updated
    • Keeping your programs (especially Adobe and Java products) updated is essential. Update Checker will notify you if any of your programs require an update.
    • Microsoft releases patches for Windows and Office products regularly to patch up Windows and Office product bugs and vulnerabilities.
    • Please ensure you update your system regularly and have automatic updates on. You can learn how to turn Automatic Updates on here

    I also recommend you to switch your antivirus program to a better one. Here are some suggestions:

    In addition to your antivirus, you need additional protection such as a firewall and behavioural blocker.


    Other steps that you may want to do to further protect your system/files:
    • Sandboxie - "Quarantines" your browser so anything that you do in it will be isolated from your system.
    • Backup important files regulary to an external hard-drive or USB

    Here are only a few suggestions that will improve your system security. Should you wish to allow us to make full recommendations and set your PC up with maximum security, please start a thread here. Our community of PC enthusiasts and experts will give you feedback and help you secure your system from future malware infections.

    Should you want to try a product but don't know how it performs, here is a list of current reviews to help you decide.

    Internet Explorer may be the most popular browser but it's definitely not the most secure browser. Consider using other browsers with addition add-ons to safeguard your system while browsing the internet.

    Firefox is a more secure, faster browser than Internet Explorer. Firefox contains less vulnerabilities, reducing the risk of drive-by downloads. In addition, you can add the following add-ons to increase security.
    • KeyScramber - Encrypts your keystrokes to protect you against keyloggers that steals personal & banking information
    • AdBlock - Disable/blocks advertisements on websites so you won't accidentally click on a malicious ad.
    • NoScript - Disables Flash & Java contents to avoid exploits or drive-by attacks
    • Web of Trust - Shows the website rating by other users and blocks dangerous and poor-rated sites

    Google Chrome is another good browser that is faster and more secure than Internet Explorer by having a sandbox feature. Additionally, you can add the following add-on to Chrome to heighten security.

    Lastly, it is important to perform system maintenance on a regular basis. Here are a few tools and on-demand scanners that you should keep & use every 1-2 weeks to keep your system healthy.
