Windows 7: Freezes, lags and sometimes BSOD when connecting to Internet

Ok, Im having this problem since yesterday, I left my computer on so i can finish my download(i nap a bit) when i woke up, my computer started to lag and freeze to the point that i cant use it(Sometimes it BSOD),,,,This only happens when i connect to internet,,When i reboot normaly without internet,it runs fine...So i assumed this is an internet problem so i restarted in "Safe mode with networking" and it ran fine(No lags,freeze or even BSOD) and now im completey confused if the problem is my internet or one of my application is trying to update and slows down my computer....Any help will be much appreciated Thanks!

No dump files.

Oh, Sorry about that, I did some cleaning before i run the Diagnostc tool,,It should be updated now

Thanks

Dump does not show a probable cause but it crashed on Avast! antivirus.
Its known to cause BSoDs on some systems.
Please uninstall. Download and install MSe and make a full scan once updated.

Microsoft Security Essentials - Free Antivirus for Windows

Let us know if the BSoD persists.

Yeah,,i was running in normal mode with internet while scanning with Avast but even if im not running Avast it still lags and freezes even in Idle,,Ill uninstall Avast and try Mse and see if it works, Thanks ill get back with the result

Sure, take your time

Wow, I just removed Avast and....Its okay now...thank you so much for the help, really appreciate it...I am now installing a new Anti-virus,,,,on a side note, Can you recommend a good AV program ?Is MSe enough for anti-virus?

Sure. Well I and many members on our forum recommend Microsoft security essentials with
a great combination of Malware Bytes.

Microsoft Security Essentials - Free Antivirus for Windows
Malwarebytes - The Free version
Good and Free system security combination.
