    Risks

    Privacy Policy:

    http://www.grokster.com/privacy.html

    Stability Issues:

    Known to considerably slow a system down causing many programs to eventually crash. When running Windows 98 and older versions of IE, instability problems can be more severe. In some cases, trying to run Grokster will cause illegal operation errors.

    Risk:

    Older versions of Grokster contain vulnerabilities including a Trojan masquerading as an advertising application. Many users have claimed in online reviews to have received multiple trojan and virus infections while using Grokster.

    Detection and Removal

    Caution!!!:

    Grokster may install CommonName, SAHAgent, and WebHancer, all of which reconfigure your network connection. If the Layered Service Provider is not deregistered properly, your network and Internet connection may be lost. The complexity of doing this properly make manual removal extremely risky.

    Installs with a trickler, and installs other products that have tricklers, ensuring that components are restored after you delete them.

    The Grokster uninstaller does not work at all -- it removes nothing.

    Automatic Removal:

    PestPatrol detects this.

    PestPatrol removes this.
