I am very satisfied with MBAM. It updates signatures at least daily & does so faster & better (very stable & reliable) than any other security app I have ever used. It scans fast and gives good explanations when it finds something. I only use MBAM on-demand because I do not feel the need for another security application running in real time. (My real-time security is Avira, Malware Defender, & Sandboxie). Thus, I only need the free version of MBAM. However, MBAM is so good that I would like to be able to donate some $$$ toward their continued success. Is there any way I can donate? (Preferably by credit card -- I detest using PayPal).
