At level 101 the start of the level is quite essential, because of the Infection spreading down at three places.
Take Care of the infection in the middle first, otherwise it spreads and becomes unstoppable in a few turns. Then go for the infection to the right and when that is taken care of take down the left side infection. You take down an infection by shooting above the viruses.
