Check the .jar files in your Maven repository opening them with WinRAR or whatever. It will take a while. You don't need to check all of them, just the ones you downloaded most recently. The repository is usually called "m2" or ".m2" and it's usually in your user profile or home directory depending on the OS you're using.
Some of those jars will have a "com" directory inside them. If inside this "com" directory there's also a "trend" directory, congratulations: you're the latest victim of your stupid corporate firewall/proxy/antivirus.
Trend Micro's antivirus is injecting code in the jars downloaded by Maven through your company's proxy. Open the .jars manually and remove the "trend" directories (also remove the com directory if it's empty after that, it could be infected with AIDS or something).
Documentation for this wonderful feature is here:
Stupid page on Trend Micro's stupid site. F### them.
I feel your pain.
