If you are using more anti-virus products on your computer and experience issues with malware detection or system performance, we recommend uninstalling the conflicting product.
It is generally not recommended to use more than one security solution on a single system. They will compete for resources, which may result in slowdowns, crashes or in no protection at all. Please see FAQ 5180 - "How to uninstall conflicting anti-virus products" for a remover application.
