For most people, Malwarebytes is the better fit because it covers Windows, Mac, Android, and iPhone and offers a broader set of security features. Choose Gridinsoft Anti-Malware if your need is specifically a Windows PC scan, cleanup, or a focused companion to Microsoft Defender. Neither is a proven detection-rate winner over the other: the available independent test evidence is not directly comparable.

They are not quite the same kind of product
Malwarebytes is the broader consumer security option. Its paid offering includes active protection and web protection, and its plans cover several major device platforms. Gridinsoft Anti-Malware is specifically a Windows product centered on detecting and removing malware, with real-time protection as well. Gridinsoft describes its detection as using signature, heuristic, and AI-assisted methods; that is a description of its approach, not independent proof that it detects more threats.
Free tools Windows power users keep installed
One-click scans. No signup required.
This distinction matters more than a checklist score. If you need a security product for a Windows laptop, Mac, and phones, Gridinsoft cannot cover the household on its own. If you already have Microsoft Defender and want a Windows-focused second opinion or cleanup tool, Malwarebytes’ broader platform coverage may not be useful to you.

- One-Handed Attachment - Convenient slider allows for quick and easy attachment to the laptop with one hand
Malwarebytes: broader coverage, but free scanning is not full-time protection
Malwarebytes’ free option is useful for on-demand checks, but it should not be mistaken for the paid product running continuous protection. Its current feature documentation lists Quick Scan and Custom Scan as free on Windows and Mac. Threat Scan, scheduled scanning, real-time protection, and web protection are listed as paid features. See the current free-versus-paid feature table for platform-specific details.
For people who want one vendor’s product across computers and mobile devices, Malwarebytes is the more natural candidate. Its pricing page advertises plans for PCs, Macs, Android devices, and iPhones, including individual and family options. The exact plan, device limit, features, and price depend on the offer shown in your region, so confirm those details at checkout rather than relying on an old price quoted elsewhere.
The trade-off is that broader features may be unnecessary if you only want an occasional second-opinion scan. Malwarebytes also cautions that installation alongside another antivirus can cause problems. Consult its guidance on using Malwarebytes with other antivirus software before enabling overlapping protection.

Gridinsoft: focused Windows scanning and a six-day trial
Gridinsoft Anti-Malware offers Windows scanning, cleanup, quarantine, real-time protection, and browser-related cleanup tools. The company advertises a six-day full-featured trial without a credit card; its support page says the trial includes on-demand scanning, cleanup, quarantine, threat-list updates, real-time protection, and technical support. After the trial, premium cleanup and protection require a paid license. It is a trial, not a permanently free full-featured antivirus. See Gridinsoft’s trial details.
Gridinsoft says the product is intended to work with Microsoft Defender and most third-party antivirus products. That is a compatibility claim, not a reason to switch on every security module from two products without checking how they interact. Its coexistence guidance is useful if you plan to keep another antivirus installed.
Gridinsoft advertises Standard coverage for one business PC or two home PCs, Family for up to three home PCs, and Extended for up to five home PCs. Confirm whether the license matches home or business use and review currency, billing term, tax, and renewal conditions on the live purchase page. The retrieved information does not support a reliable like-for-like price comparison.

Its system-requirements page recommends current Windows 10 or Windows 11 installations. Some older versions may technically run the application, but that does not make them secure: Windows 7, 8, and 8.1 no longer receive normal Microsoft security support. Windows XP and Vista are not supported by Gridinsoft. See its system requirements.

- You have a mixed-device household: Choose Malwarebytes if you want a single vendor with plans spanning Windows, Mac, Android, and iPhone. Check that the plan includes the devices and features you actually need.
- You need to scan or clean one Windows PC: Either can be considered as an on-demand cleanup option, but available evidence does not show that one removes more infections. Gridinsoft is the more Windows-specific choice; Malwarebytes Free can provide on-demand scans within its stated limits.
- You want ongoing protection on Windows: Compare the paid features of Malwarebytes and Gridinsoft with Microsoft Defender and current independent tests. Do not infer superior protection from a larger feature list.
- You already use Microsoft Defender and want a companion: Gridinsoft explicitly says it is designed to coexist with Defender. Malwarebytes can also be used in some configurations, but its support documentation warns of potential issues with another antivirus. Prefer one real-time antivirus and use a second product for on-demand scans unless a compatible setup is clearly documented.
- You want to try the full product before deciding: Gridinsoft offers a six-day trial without a credit card. Malwarebytes Free is an ongoing limited scanner, not a full trial of all paid protection features.
- You use a Mac or phone as well as Windows: Gridinsoft is not a cross-platform household solution. Malwarebytes is the broader option, though feature availability varies by operating system and plan.
- This is a work-managed computer: Follow your organization’s security policy and contact its IT administrator before installing another security product. Consumer licenses may not be appropriate for business use.
Running Malwarebytes or Gridinsoft alongside Defender
Having a second scanner available can be useful; running multiple real-time security layers is a different decision. Overlap may cause duplicate web filtering, repeated alerts, slower scans, conflicting quarantine actions, blocked installers, or higher resource use. Gridinsoft’s compatibility statement and Malwarebytes’ caution are not necessarily contradictory: behavior depends on the products, enabled modules, and configuration.
A cautious setup is to keep one primary real-time antivirus, then use a second product for an on-demand scan when needed. Avoid enabling duplicate web-protection modules unless the vendors document that configuration. If you install a product, watch for unexpected warnings or performance changes and review exclusions carefully; do not exclude broad folders such as Downloads or your entire user profile without a specific reason.

If a computer may already be infected
Neither product should be treated as a guaranteed cure. For a normal Windows session, use this recovery sequence:
- Protect sensitive accounts. If compromise is suspected, avoid signing in to banking, email, or other sensitive services on the affected PC. Change important passwords from a known-clean device and enable multifactor authentication.
- Use an official download and update it. Get the installer from the vendor’s official site and update its threat information before scanning when possible.
- Run an on-demand scan and quarantine detections. Follow the scanner’s prompts and restart if it asks. Quarantine is generally safer than manually deleting files because it preserves a route to review or restore a detection.
- Scan again after restarting. If the detection returns, investigate persistence or reinfection rather than repeatedly deleting the same file.
- Check likely re-entry points. Review unfamiliar browser extensions, changed browser settings, startup items, scheduled tasks, and suspicious downloads. Be cautious about removing system items you cannot identify.
- Escalate if normal scanning is blocked or symptoms persist. Microsoft Defender Offline or another reputable rescue environment may help when malware prevents installation or scanning. If system integrity cannot be trusted, restore from a clean backup or reinstall Windows.
Different scanners may report different detections because they use different signatures, reputation systems, heuristics, scan locations, and policies for potentially unwanted software. Compare the file path, publisher, hash, behavior, and quarantine status—not just the number of results. A clean scan also does not prove that stolen passwords, browser sessions, altered DNS settings, or a compromised router have been fixed.

Malwarebytes appears in retrieved AV-Comparatives 2026 materials, including Malwarebytes Premium 5.5 in the Malware Protection Test material. Gridinsoft did not appear in the retrieved participant list. This gives Malwarebytes more visibility in the cited independent testing, but Gridinsoft’s absence is not evidence that it performs poorly.
Best Value
- Protect laptops from theft. Designed for laptops with no dedicated lock slot. Alternative to Kensington Locks.
- Works with Macbooks, Surface, Dell, Lenevo and all other major laptops, tablets and notebooks that have a 3.5mm audio port (headphone / AUX port)
- Extremely durable cut resistant steel cable to tether to to desks, tables, or any fixed structure
- 1.7 metre cable length providing both flexibility and convenience in cable management
- Resettable 4-digit combination lock with 10,000 possible combinations. Easy flick switch to lock and unlock for fast setup.
Most importantly, the available material is not a direct, same-conditions Malwarebytes-versus-Gridinsoft comparison. It cannot establish that either product detects or removes more malware than the other. For context, see the AV-Comparatives 2026 Malware Protection Test material and its 2026 Real-World Protection Test material. Test results are one factor alongside compatibility, usability, support, and cost.
Verdict
Pick Malwarebytes if you want broader device coverage and a fuller consumer security offering, and are willing to pay for features such as real-time and web protection. Pick Gridinsoft Anti-Malware if your need is specifically Windows malware scanning and cleanup, you value its short full-featured trial, or you want a Windows-focused companion to Defender. If you need a detection-rate winner, the available evidence does not justify naming one.
Whichever you choose, keep Windows and applications supported and updated, maintain backups, and secure accounts with unique passwords and multifactor authentication. Antivirus software is only one part of a secure setup.
