Windows Laptops comes a inbuilt antivirus called Windows Defender.
What is Windows Defender?
Well as stated above it is a windows builtin defender, to protect you against viruses , malwares and shitty spywares.
It is not a cool name Antivirus , eeww...
Despite the idiocy that you may think its not cool, it is alone enough to protect you without compromising your performace, especially for a low end pc's.
What to do then?
Just keep the Defender up to date and you will be safe no matter what. If some s*** happened to you then remember , update it.
Scan at least once a month but always keep your defender up to date.
You need to have an antivirus for windows 7 and previous. But yes Win Defender is a good protection
Windows defender is all you need, the problem is a lot of false positive (I didn't download files, I used source codes which got detected as a virus)
I have found that Windows Defender AntiVirus is quite good as a free builtin tool, its not as bad as most reviews claim. Just keep the definitions updated, Its good enough for most people. But if you don't mind the ads popping up, I would suggest the Avira Free AntiVirus. Its a bit better.
If you are tech-savvy and are using the Windows machine for personal use, then you are pretty much fine with just defender. The only time you REALLY need something powerful enough to cost a decent amount of money is if you are being targeted by someone or click onto things without much thought. For those types of people though, all you need is Webroot or something else cheap to make sure they don't install a virus and grant it admin permissions. Servers, however, are another story. Especially high profile, public projects.
Windows defender is might be a good choise but more important ist to install updates to keep you system safe.
With outdated Software you invite the hackers to enter your system easily.
Well, to be honest. I personally HATE windows defender. It's memory consuming, it scans so many files slowly before you can open it. On older PC / Laptop, it'll definitely slow you down.
I Always disable windows defender and install some other free antivirus like Avast . It's better in my opinion. I use it on every PC / Laptop that i have or the one that i repaired. Even if i update the windows defender frequently, i don't feel safe just like when i use any other antivirus.
It's true that it'll be enough for 'basic protection' , but i still recommend you to use something else rather than Windows Defender. Oh, and another thing, sometimes there are local virus that cannot be identified by international antivirus, so you gotta install some local antivirus too!
I don't really like Windows Defender. Mainly because it doesn't tell me what it deletes (having to check event logs each time is annoying), and also keeps flagging the file I added to exclusions list, but at least doesn't delete it.
I used to use avast, but I had problems with it aswell. Mainly it ignoring the exclusions list, scanning my pc in the background without any consent/notification and not responding after switching to the secure desktop/right clicking the icon.
Currently I only have Malwarebytes and that's enough for me, because I'm actually careful and I don't open untrusted exe files without scanning them on virustotal, running them in sandboxie and doing a few other things first. And it really works, because the last time I had any virus was when I was like 9 years old.
