No I didn’t change anything regarding fonts. That’s only how that skin looks like on my system or on any other system that has ADOBE TYPE MANAGER 4.1 installed + LUCIDAGRANDE (spot that it is only one word, there is also Lucida Grande font, but I’m not using that one). LucidaGrande font that I’m using contains two files: PFB and PFM extensions, not standard FON or TTF extensions. If someone doesn’t have Adobe Type Manager installed, he/she can not see that font in Lite-On skin. avast! automatically substitutes that font with some other standard Windows font.

You can read about Adobe Type Manager in here:

That’s why my font in Lite-On looks so smooth.
