i would also like to thank you for patience and cooperation without which this issue wouldn't have resolved . thank you !!!
first ,
i downloaded norton antivirus then i ran a scan it detected a few risks(virus).
but that wasn't the end of the problem . whenever i ran the internet norton kept popping up and it said 'an intrusion attempt was blocked' . after that still the bluescreen used to appear then i just googled the risk it kept showing it redirected me to a website where it told me to download kaspersky tirdsev trojan detector. it found one risk and told me to re-booted and as a part of the step i had to download malware-bytes anti malwarebytes and it detected some risks after that it re-booted and the problem was gone .
could you please tell me how to close this post and what was my problem???
i just love this site .
thank you .
