One thing I have experienced is that certain Motherboard suppliers infest their users with BCU (Browser Configuration Utility), a parasitic implant that does absolutely nothing for the unfortunate user but hog the memory and generate a huge number of events. It is also said to slow down the computer and dominate browsing freedom. My Firewall logged over 10,000 BCU records in no time at all under "Processes Detected", a massive log of irrelevant events, all due to BCU activity. My Motherboard is supplied by Gigabytes Technology but another Motherboard that infests the poor user with this BCU plague is Asus, there may be others. I uninstalled BCU with Revo Uninstaller, getting rid of all leeching remnants of it and life is now good, not a wisp of operational efficiency detected in being without this BCU parasite and my FW is no longer trying to burst it`s capacity (and my memory) keeping up with those thousands of insignificant and useless BCU event logs. Conclusion :- If you have BCU contaminating your PC, then DUMP IT quick !
