Please help me to point out a mistake in this following sentence: The hardware of that computer was infected by some new viruses. I would change "by" into "with". The matter is there's no "by" in choices offered as mistakes.
Top answer
I see no grammatical mistake. Perhaps they want you to change to the singular "by a new virus". I agree that "with" would be better.
