I scheduled a Daily scan at 1pm (only takes 3-3.5 minutes)-

When I scheduled- they recommended once a week? 

Changes take several days to take effect?

Should I change it to weekly, and which day is best?

Any scan, especially on-demand scan takes CPU resources. If it takes only a few minutes to scan your PC, it's ok to scan it once a week. However, with further files being created the scan time may increase substantially, especially if you save big archives to the disk. Personally I don't schedule any on-demand scans since files are scanned upon access and execution by real-time protection and HIPS-based protection modules. That said, an on-demand scan may detect threats in archives, however, in this form the threats do not pose any risk since they would be detected by real-time protection upon extraction from the archive.

Thank you for the detailed reply!-

The main reason I do a Daily scan, is for rootkit detection (I was infected before ESA). Are they scanned for, when I open Google Chrome?

You are correct about scan times increasing!

I will stop scan, and let you know?

Rootkits are not common these days. Moreover, ESET leverages Anti-Stealth and scans objects in startup locations to detect malware at an early stage of system startup, including possible active rootkits. If you are concerned about rootkits, you can run a disk scan with ESET SysRescue from time to time.

I removed the Tick from Daily scan yesterday, and my system is Much Faster today...

After two months of Daily scans- I probably have Huge created scans...!"-

How do I permanently Delete them?

If you mean how to delete generated on-demand scan logs, you can keep them unless they are really huge and take up disk space. Logs are deleted after 90 days automatically by default or you can delete them manually after selecting "Computer scan" from the drop-down menu in the Log files window.

I removed the Tick/ got a Win confirm, but the Daily Scan scheduler I created is still there!?

I would assume that it is still being loaded, in case I want to later run it (Not!)-

How do I completely delete/remove it? see snip-
