This is a great forum, I should have seen this earlier.
The sequence of events leading to BSoD:
(i) I visit a site
(ii) I get a Windows prompt asking for permissions to download some file
(iii) The Antivirus (Symantec) kicks in, before I could respond to the prompt.
(iv) I get a BSoD
Repeated attempts to reboot the machine in various modes caused the BSoD and the system doesn't boot up to Windows. Finally I could get past the BSoD in the "Debugging Mode" where I followed the steps specified in "Malware and Spyware Cleaning Guide".
I have attached the three files from :
MBAM
RootRepeal
OLT
I suspect one of two things causing BSoD:
(i) Some malware
(ii) The Symantec Antivirus while attempting to clear some malware while I visited the site.
Should I suspect some malware?
Thanks in advance.
