I use ad-blockers, ads slow down the load time of the internet on my laptop because I don't use ethernet, but it is configured for exceptions like Sysnative Community.
Unfortunately I'm very curious so if I visit a site for which exceptions are configured I need to be careful with the ads these days.
I use Malwarebytes Anti-Malware, Malwarebytes Anti-Exploit and Bitdefender Total Security.
I only have Windows 10 in VMware, it could be possible that Bitdefender causes a few crashes in the newest version as the newest version is still pretty new (as is Windows 10). BTW, I have Bitdefender only seen causing crashes with 0x4A(IRQL_GT_ZERO_AT_SYSTEM_SERVICE) crashes where, 1 of the BSOD experts has written an excellent explanation why Bitdefender causes this crash if I remember it correct.
