No, it is certainly not affected in any way.
Taking a look at the Global Terrorism Database (arguably the most comprehensive listing of terrorist attacks) for incidents in Eastern Europe from 2011 to 2015, one can see that there have been a total of 1440 deaths from terrorist attacks. However 95% of those are either a part of the war in Donbass (1023 deaths) or part of the Islamic insurgency in the Russian Caucasus (390 deaths). This leaves only 27 deaths for other countries in the region, which is very much negligible as far as risks go.
The only significant terrorist attack (outside of Donbass and Caucasus) in recent times has happened in Bulgaria, where 7 Israeli tourists have been killed and 32 have been injured.
