BSOD when running utorrent- recent development

[NoviceM]

I am running Windows 7 Home Premium x 64 Service Pack-1 on a custom PC with i3 processor & 4GB Ram. I started getting BSOD around a week ago- whenever I use utorrent. Sometimes I get the BSOD within minutes of starting the utorrent, sometimes after several hours. I have been using utorrent on this PC for many months now but have never had this problem before. I have a feeling the BSODs started after a Windows Update I did around the middle of last month.

This is the Additional Problem Info on the latest BSOD:
Problem signature:
Problem Event Name: BlueScreen
OS Version: 6.1.7601.2.1.0.768.3
Locale ID: 1033

Additional information about the problem:
BCCode: d1
BCP1: 0000000000000028
BCP2: 0000000000000002
BCP3: 0000000000000000
BCP4: FFFFF880014106FD
OS Version: 6_1_7601

I do not have much knowledge of the working of computers, so I really would appreciate any help in solving this problem.

Attached is my minidump in a zip file. Please do let me know if I need to provide any other information. Thanks

Hi Anshuman. Uninstall Quick Heal. Use Microsoft Security Essentials as your antivirus with windows inbuilt firewall, and free MBAM as the on demand scanner.

Report us for any further BSOD.
