BSOD only when I use uTorrent

I used to use utorrent without trouble until all of a sudden I started getting the BSOD every time I used utorrent. I have read aa lot of the post's here and it appears to me each ones BSOD problem is unique. I'm using a dell N5040 laptop: win 7 home premium,SP1, i3. I have zipped and attached the minidump files. I'm no tech expert and hence require your help....thanx

Looks like your network driver doesn't like the torrent downloading... You may try updating the network driver. What antivirus/antimalware programs are you using? They may be affecting the network driver

I'm using avast (free version). I'll update the network drivers and see how it responds...will keep you posted Tmagic650, but why did this problem begin all of a sudden?

Remove avast and download and install free Microsoft Security Essentials:
