Now about one week from the installation, right NOD32 user interface window doesn't have "custom look"any more. It looks like as if NOD32 was installed with "standard Windows" interface option (but left window still with NOD look). Even reinstalling does not solve problem. Not like a big deal, but with AV products, one small malfunction could indicate something bigger. Interesting, I have noticed similar effect with almost any NOD32 version I have tried.
