Hello there everyone! I recently built a PC, and I have been noticing a command prompt box flashing (for probably just a few tenths of a second) after I log into my account (running on Windows 10). I was just wondering if this is normal, or if this is something I should be concerned about. I've been running tests through Windows Defender and Webroot, and they have not detected any viruses or malware. Is there anything else I should be doing or looking into if this situation warrants it? Thanks in advance!
