Running Superantispyware the problem is resolved.
I do not know what exactly it was as it detected some 488 adware etc but now Chrome runs smoothly and fast.
It is bad that Eset NOD32 could not detect it as I run a thorough in depth scan...
I have found this infection and I have all the symptoms described here:

Nod32 cannot find it. I found it with WiperSoft.
How can I remove it?
