Antiperspirant deodorant isn’t good for you with the Aluminum. I used Antiperspirant for a while it worked good on me. Then I switched to something more natural. I smelled really bad for a month after the switch, tricks so you don’t smell bad try different brands some work great and some don’t work at all for oder control, I like Shmitts, Hello and Native. Before I took a shower or anytime I had oder I used a Alcohol pad to wipe my armpits and apply deodorant as needed, during shower time when I shampoo my head and shampoo my pits. Over time I use natural deodorant once a day without having a bad smell.

Why would you install a program like that? The name alone sounds like malware. Anyways windows has a default firewall that works good and does the job, and your router is a hardware firewall that blocks all unsolicited packets too your local network.
