Help !
My PC is infected by unknown virus: when I surf on Internet, especially on webmails, it blocks for ever and doesn't send e-mails or even access received e-mails. The "funny" thing is that it starts this behaviour after a short while working properly …
I use Mozilla Firefox. I tried Avast scan and Kaspersky scan, but it doesn't help. Kaspersky seems to find things, but on old outlook archives I don't use any more… Moreover, it cannot fix the problem, but I doubt it is the reason for the problem I have lately, as I don't use those archives since more than two years …

Here is the resut of HijackThis on my computer …

Can someone please help ? Thanks a lot in advance !
