Explanation
★All three statements about malware are true, so the answer is 1, 2 and 3.
★A Trojan Horse hides malicious code inside apparently legitimate software.
★The user is tricked into running it, and it then acts against the system.
★A virus attaches itself to another program and executes when that program is opened.
★The virus spreads as the infected program is shared and run.
★A worm is self contained and needs no host program to run or spread.
★It replicates and travels across networks on its own, unlike a virus.
