Blocks Ransomware Sources: With the newest types of ransomware now being created to bypass traditional digital security, it’s more important than ever to have next-generation antivirus protection. That’s why Heimdal filters every website you visit for the latest ransomware sources and blocks them before they can take your device hostage.

You need a layer of protection between your computer and the infected content floating around on the Internet. Heimdal Antivirus acts like an iron curtain, blocking malware from any source before it can infect your device and infiltrate your valuable data.

Protects Your Bank Accounts: Online banking scammers are everywhere, just waiting for a crack in your computer’s defenses to swoop in and wipe out your accounts. Heimdal Antivirus is like a virtual security guard that stands watch as you shop online or log into your credit card or bank accounts.

The Good

Automatic Closing of Security Holes

It’s been shown that up-to-date software closes over 80% of security holes that allow hackers to access your device. Thor Foresight helps protect you from cyber-criminals by automatically updating your downloaded apps to prevent security breaches on your Windows computer. And it’s all done without any interruptions or restarting of your device.

Smart Sandbox Inspections

Worried about what dangers could be lurking in your computer’s files? Heimdal Antivirus uses sandbox inspection to stop malicious content before it can infect your device. If any dangerous files are found during a security scan, Heimdal Antivirus quarantines them to keep your PC safe and adds that info to their threat database to prevent future infections.

The Bad

While Heimdal Antivirus products seem a bit pricier than other options on the market, we were impressed by the unique and proactive protection they provide. And it was refreshing to see that each of the annual subscriptions cover multiple Windows devices.

When testing Heimdal antivirus products, we also noticed that they lack phone or live chat support for users. But when we submitted questions via an online support ticket, they were answered quickly and thoroughly.

The Bottom Line

Heimdal Antivirus is on the pricey side and lacks instant support, but the AI-powered and proactive protection it provides for PCs make it well worth the few extra dollars. Plus, we didn’t notice any performance slowdown and really liked the clean user interface.

Windows users should absolutely give one of Heimdal’s antivirus products a shot, especially if they do a lot of online banking or shopping. To be honest, with next-generation threat detection and the added security that comes with automatic app updates, it’s pretty much a no-brainer.
