No! It shouldn't be. Plants Vs. Zombies should be clean, playable and safe. If you have a minor lag after playing it, then it must have a Malware. Be sure that the copy of Plants vs. Zombies you have is 100% original. Some crackers just cracked the game using bots and other files. This can leave an imprint to one of the game files. Sometimes, the virus will hangout in the "bass.dll" file in the main directory of Plants Vs. Zombies. You must download and install a clean copy of the game to resolve this.
