Microsoft veteran Raymond Chen warned that running multiple antivirus programs on Windows 11 causes conflicts, citing a case where two anti‑malware tools quarantined each other’s processes. Chen explained that the programs, unaware of one another, treat each other as intruders, leading to false quarantines, performance degradation, and system instability. He noted that third‑party AVs may use unsupported techniques like detouring system functions, further aggravating issues. Microsoft’s own Defender is deemed sufficient for most users, and the company recently removed a promotional document that had labeled it the “best antivirus software.”
