I did a scan using GRC shields up at www.grc.com .The result are as follows :GRC Port Authority Report created on UTC: 2020-08-12 at 02:23:47Results from scan of ports: 0-1055    0 Ports Open 1050 Ports Closed    6 Ports Stealth--------------------- 1056 Ports TestedNO PORTS were found to be OPEN.Ports found to be STEALTH were: 135, 137, 138, 139, 445, 646Other than what is listed above, all ports are CLOSED.TruStealth: FAILED - NOT all tested ports were STEALTH,                   - NO unsolicited packets were received,                   - NO Ping reply (ICMP Echo) was received.

I am using latest kaspersky internet security 21.1.15.500

This question is a relic from a bygone era. Because of how Kaspersky operates, the GRC results are meaningless and useless. You can ignore GRC results.

ok thanks for the answer.
