I’m not kidding. It not just sucks network but also sucks your everything inside your lovely computer. 
Here the reasons that make me hate this product 
1. It’s freaking heavy, 
even if your hardware are good, Norton sucks all best of your hardware.
2. Tons of services load at startup 
and run in background mode. It sucks on timing there.
3. After installation, it’s everywhere in your data and documents. However, when you uninstall it, either through Windows Uninstaller or Norton Removal Tools, you’ll never get rid of it. It still remains the leftover somewhere in your computer 
. Therefore, it sucks on management.
4. If you’re on network connection, you will get disconnect very often. Firefox goes on a “Failed to Connect”, IE just keeps on a “Webpage cannot display”, it’s because of 
Norton product. As you see, it sucks your network.
5. Finally, it’s so expensive . That’s it! It sucks your bank account.
That’s why I hate it very very much since it SUCKs your life. My suggestion, don’t burn your money for this product.
Don’t believe me? Well then, go ahead and give it a try. Remember, don’t complain because you’ll suck your own 
afterward.
