Windows 7 hangs every time I open any application that connects to internet. Chrome, IE, Outlook, VLC Player all have the same problem. This problem started appearing only since yesterday.

Its frustrating because these applications go into 2+ minutes of non-responsiveness before opening. Also, at times, McAfee security center automatically stops. I tried all the following things, but nothing helped:

  1. Disabled security center completely, restarted the machine & tried - NO LUCK
  2. Checked the Resource Monitor-all CPUs are 100%. Not sure how monitoring wait chain can help
  3. Scanned disk for errors using CHKDSK - No issues
  4. Tried in Safe mode with networking - Same issue

Running out of options and patience. Please help!!

Does it continue to happen if you uninstall McAfee? –  Karan Apr 12 '13 at 19:27

I didn't uninstall McAfee. I have completely stopped all McAfee services. –  Mahesh Apr 12 '13 at 19:42
    
Have you tried System Restore to a date before yesterday? –  CharlieRB Apr 13 '13 at 1:23
    
Have you investigated any driver issues or possible updated drivers for your network adapter? –  Moses Apr 13 '13 at 4:26
