Currently I'm using OA free and Avira free as real time guard. First,I noticed OA free does not provide keylogger protection.Secondly,I'm not sure if OA free's HIPS is as good as Comodo D+. I use SAS and MBAM free to do on demand scans. I want to add another real time protection(free).If I add another HIPS,would it be an overkill or cause some conflicts with OA's HIPS? What's your opinions plz?
