I've had bad experience with my Windows Vista OS, because hackers usually get viruses on my computer. I don't want to pay a lot for a program like Norton, so I'm wondering if there's an antivirus program that's free that can:
Detect webpages/downloads that will get a virus on my computer, so it can warn me when visiting a site that installs harmful malware
Protect against hackers when they try to hack and invade my computer through server requests, etc. (I don't know how they do it, so whatever)
Sometimes hackers can be sneaky, so I don't always know when there's malware on my computer when hackers don't make it obvious that there's malware that reads when you type bank passwords, etc.
