I have a friend who works at
https://soax.com/buy-bulk-proxy, so I should ask him for advice. Tbh, he knows everything about VPNs and proxies literally. Actually, I've never used any PC security apps. I mean, I don't understand why to use it. I have an iMac, so it has a brilliant security system, that's why it's really difficult to get a virus while downloading something. Anyway, thanks for your advice. Hope it will be very reasonable for somebody here. Wish you all the best, folks.
