denzilla 0 Posted March 19, 2021 Share Posted March 19, 2021 There is quite a bit of a performance hit when cold booting PCs with traditional HDDs due to Startup scan. If the resident real-time scanner is doing its job, isn't the startup scan redundant? Link to comment Share on other sites More sharing options...
Administrators Marcos 5,278 Posted March 20, 2021 Administrators Share Posted March 20, 2021 Yes, it's necessary. Unlike real-time protection startup scans scan also operating memory as well as startup locations, including WMI and registry. However, they should not have a noticeable effect on system performance. What is the hw configuration of the pc in question? Does uninstalling ESET installing it from scratch with default settings (with LiveGrid enabled) make a difference?

My boot drive is a SATA III; i,e. 6 Gb/s, plus my motherboard and CPU are 12 years old. I have no performance impact due to Eset startup scan. Also, it only runs for 10 - 15 secs at most.

denzilla 0 Posted March 21, 2021 Author Share Posted March 21, 2021 (edited) Weird. It goes on for a few minutes on all our machines and the HDD churns. No performance impact on an SSD equipped machine. Admittedly, this could also be a combination of other processes fighting for I/O as the machine finishes boot. My post was more curiosity about the actual need for startup scan though. HW configs vary from 4th gen i5's with 8GB ram and up. Most have spinning rust. All Win10 Pro 64-bit. @Marcos So real-time scanner doesn't actively monitor those locations while the PC is running?

Administrators Solution Marcos 5,278 Posted March 21, 2021 Administrators Solution Share Posted March 21, 2021 Real-time protection scans files. It doesn't scan locations where fileless malware is stored. Link to comment Share on other sites More sharing options...
