antivirus malware

HP Recommended
HP 15t
Microsoft Windows 10 (64-bit)

HP tech support told me that I should not have installed Bitdefender antivirus appl  while he was troubleshooting my notebook known issue of logging in screen blank, cap three long blink with two short blinks....

I see HP store has only McAfee, though McAfee can have a business deal with HP.  

Which antivirus/security protection can I install to my HP notebook?

yes I know windows 10 comes with Window Defender, since Windows Defender has cons, I like to hear opinions?

I use these....


As to those blinking codes...



3-2 suggests a BIOS and/or RAM problem.


"HP tech support" which I hope was a Lo-Cost/No-Cost opinion, preferably FOC.


RAM for your PC.  Either get a scan done by Crucial or Kingston or look at HP's info.


Since HP 15t gives 

Matching products for United Kingdom (133)


so the SKU: or Product number please.


Plonk it in here --

and it may very well list what it was built with.


ELSE plonk it in here -  -  for the Manuals etc.

but the HP technical support who opened a case for my notebook and HP fixed the cap lock blinking 3 long and 2 short, login issues, says don't install Bitdefender for HP computers.

so Kaspersky is better than norton or Mcafee?
