AB Download Manager is Safe to install of not?


AB Download Manager is 100% safe to install, but to my surprise, when I scanned the downloaded .exe file on VirusTotal.com, one security vendor flagged it as malicious. However, there’s no need to worry—this is what we call a false positive.

The alert came from Bkav Pro, which detected “AI Detect Malware”, making it seem unsafe. But this isn’t a serious security risk. To be sure, I also scanned it with Kaspersky & Internxt, and both confirmed the software is safe.

That said, the developers should fix this issue in their next update. It’s not a hacking bug, just a minor detection glitch.

My Personal Experience Using AB Download Manager

AB Download Manager User Experience

Unlike FDM, when I download a file through my browser, AB Download Manager’s Download Tab opens instead of launching the full application. This makes it feel more integrated and natural, just like IDM.

I really like this because it doesn’t feel like a separate application running in the background—it blends smoothly with my browser. The experience is intrinsic and effortless, making downloads feel like an integral part of the browser itself rather than an external tool all because of Chrome Browser Extension support.

AB Download Manager’s Queue & Scheduler for Systematic Download


One of the standout features of AB Download Manager is its ability to add multiple files to a queue and schedule them for a specific time. This is a feature usually found in paid software like IDM, so I was surprised to see it for free in AB Download Manager!

That’s the power of open-source software—many developers contribute to making premium-level features available to everyone.

It’s super easy to create and manage queues:

  1. Click a download link – The AB Download Manager Download Tab pops up.
  2. Instead of clicking “Download”, choose “Add”.
  3. A popup appears, asking if you want to include it in a queue.
  4. You can select an existing queue or create a new one by clicking the “+” icon.

By default, there’s a “Main Queue”, but I created my own, like “My Favorites” & “Movies”, to keep my downloads organized and in order.

This feature is a game changer, especially for Anime & Web Series lovers like me! I can queue up episodes in the correct order, so they download sequentially without any mix-ups. No more scrambling through files to figure out which episode comes next!

I also love how easy it is to manage downloads—I can rearrange files, control how many download at once, and even set it to stop automatically when done. It’s like having a personal download assistant that works on autopilot while I sit back and relax!

Is AB Download Manager lightweight, or does it slow down my computer?

I tried running AB Download Manager along with Internet Download Manager (IDM) and Free Download Manager (FDM). I am really shocked when i see the result. AB Download Manager consumes more CPU & RAM usage when compared to IDM & FDM.

So the Answer is Big No. AB Download Manager consumes high resources and will might slow down your computer for sure impacting other computer performance.

Speed & Performance of AB Download Manager


AB Download Manager splits files into multiple segments, allowing downloads to run up to 10x faster than a typical browser. This is the same technology used by IDM & FDM, helping to speed up large file downloads efficiently.

High Resource Usage, Slow Speed – AB Download Manager consumes more system resources compared to IDM & FDM, so I expected it to deliver faster download speeds. But to my surprise, it turned out to be the slowest of the three! While IDM & FDM maintained speeds above 1MB/s, AB Download Manager struggled at an average of 200KB/s. This high resource usage simply doesn’t justify its performance, making it a letdown compared to its competitors.

Pro Tip: After testing AB Download Manager alongside Free Download Manager (FDM), I noticed a significant drop in speed with AB. Even when downloading the same file at the same time, FDM was faster. I even tried running them separately, but AB still lagged behind. Plus, it consumes more system resources, which isn’t great for long-term PC health. My advice? Skip AB Download Manager and go for FDM—it’s lighter, faster, and more efficient.

If system performance matters and money isn’t a concern, investing in a paid IDM is the best choice for the long run. It ensures faster downloads while keeping resource usage minimal.

AB Download Manager gives you advanced customization options to fine-tune your downloads. Just head to:
Settings ➜ Download Engine

Here, you’ll find various settings that might help optimize your downloading experience. Take a look and adjust them to suit your needs—you might just find a tweak that enhances speed and efficiency!

Conclusion


AB Download Manager is a decent alternative to the default browser download tab, but from my experience, it doesn’t significantly boost download speed compared to Free Download Manager (FDM). While it does support pause & resume and queue-based downloads (a feature missing in FDM), it comes with a major downside – high CPU & RAM usage.

Most importantly, VirusTotal flagged it as malicious due to one security vendor out of 57 detecting an issue. Given its performance limitations and resource-heavy nature, I’d recommend skipping AB Download Manager and going with FDM instead—it’s lighter, faster, and more reliable!
