It's free and there is still a download link for v6 on their website.
How is it? Should i go for it(free version of course) over F Secure safe?

Norton:

1) Often fails to completely remove a malware. It leaves 0 KB file of the malware in the directory.
2) Less important problem: Signature & Heuristics somehow collide sometimes. Often while detecting two files of same malware, one will be detected by signature while other by heuristic. If a malware is repairable without deleting the whole file, the one that is detected by signature is repaired but the one detected by heuristic will be deleted. Very few malware is repairable nowadays so it's not a huge deal.

This has been ongoing for a very long time when trying to log into My Norton account:

It's a known issue and ongoing bug!

At first I was just going to leave the topic as it is in the BD 2019 section, but something came up. After encountering an infected webpage earlier today and going to the notification center to investigate further, I found out that the ability to exclude a webpage through the notification center without requiring a password has returned. This had been fixed in 2019 version but made a comeback in 2020 version.

Password vulnerability

I had to use Kaspersky Security Cloud to exclude websites by URL. I could not find this option in the Free Antivirus package.

Avast seems unable to deal with a threat on the desktop.The file is malicious and reported by avast on VT,yet no reaction from avast in real time.
Only when I right click scan with avast does it detect the threat...Is this a known issue or the way avast works!?

which is extension of the file? Avast by default only scans certain extensions in realtime protection, if there is no extension or the extension is not in the list, it will be ignored
On-demand scanner supports all extensions + heuristic level is set to High by default
you can enable avast to support all extension on realtime protection

Thanks!!:)
It's a .js extention.
Okay so I will change the settings you recommend.
Overall avast seems to be very good..What are your thoughts?

I think avast is very good only with proper combination. In my test, I only combine hardened mode aggressive + syshardener exclusively, they will stop almost all malwares in the hub except for some malwares which has the extensions of .com, .bat, .cmd, .ps1
Signatures, cloud and BB are supportive. HM and SH are the main players
for this reason, I disable as many avast's components as possible to make it lighter

.bat, cmd: because we can't disable command prompt. It's crucial to windows => Chineserarypt-like malwares can infect my combo, in theory. However, you can dissociate them and only run cmd script by manual typing
.ps1: we can disable it because not many people use powershell
.com: you can dissociate it so it can't be executed

For all 3rd party AVs except ESET. Stupid leftovers after uninstall that are not removed and keep running in background and uninstall can break components. For example KAV remover can break system restore.
It's always a problem, I use Revo Uninstaller to scrub system, seems to do good job even removing register keys.
