Since you mentioned low memory and speaking in general terms, I think most AV come with extra features other than just a core AV engine. Spybot also offers real time protection components. So does the paid version of MBAM. These features could overlap/conflict in what they are providing. You could disable the similar features in one or the other. May free up system resources. May take some experimentation on your part to see what works best. I am not really familiar with either one.
Panda Cloud AV according to Panda is lighter on system resources. Easiest thing to do is uninstall Avast, reboot and install Panda, you can always switch back or try another AV.
Panda defaults are to install a security toolbar and set default search to google, i would uncheck these during the install process.
Sygate was great in its time but its no longer supported/developed and I think the last version came out 7 or 8 years ago and for this reason I wouldn't use it.
