NOD32 for Mac is changing to defaults

I have downloaded trial version of NOD32 for mac...surprisingly, it changes my wallpaper to default after every restart together with adding AppStore icon to the dock...I am running Snow Leopard 10.6.6.

thanks for the answer.

 

Hello,

I suggest that you uninstall ESET Cybersecurity, by clicking the install package in your Downloads folder (or the default folder set by your browser) and double-clicking the Uninstall icon and following the guided uninstall instructions.

Once ESET Cybersecurity is uninstall, reboot your system and see if the issue continues. If not, reinstall ESET Cybersecurity (make sure that you
have downloaded the latest trail version of ESET Cybersecurity), and verify
if the issue continues.

NOTE: Before installing ESET Cybersecurity you must uninstall any existing antivirus solution.
