Is it still safe to use Windows Vista?

Unfortunately, no, Windows Vista is not safe. Microsoft has stopped supporting Windows Vista, which means they are no longer producing software updates that could patch vulnerabilities and stop emerging threats. Because of this, Vista devices are incredibly vulnerable to both new and old malware.

How do I make Windows Vista safe?

Fortunately, it’s very easy to do that: just download powerful Windows Vista antivirus software. For best results, you should look for a Windows Vista antivirus that’s trusted, can remove viruses currently on your system, and is updated regularly, so it can protect you from the latest threats.

Does Avast antivirus work with Windows Vista?

We still support Avast Free Antivirus for Windows Vista to an extent, updating our virus definitions to ensure that our users continue to get protection against the latest malware threats. However, we no longer update our Windows Vista antivirus software with new features, nor do we offer technical support for people who are using our Windows Vista antivirus. This means that while Avast Free Antivirus will keep your Windows Vista device safe, for best results, you should consider updating to a more recent operating system.

What makes Avast one of the best free antivirus apps for Windows Vista?

While Avast may not offer technical support or feature updates to our Vista security anymore, we’re still one of the best free antiviruses for Windows Vista on account of the fact we keep our virus definitions up to date, which means you’ll still enjoy essential protection from zero-day threats. Plus, our virus scanning and removal tools will find and remove any malware currently on your system, which means it works as both a preemptive and a reactive security tool.
