4 Free Antivirus With 60 Multi-Engines – Best Antivirus Protection

Home » Computer and Internet Security » Download Free Antivirus [ Windows / macOS ]

Can I install Norton Antivirus and Kaspersky on my laptop? or can I install Norton and AVG on the same desktop? The answer is no. The reason being that having two or more antivirus software installed on a system will cause Microsoft Windows to be sluggish, this is because both anti-virus will try to out-scan each other.

Traditionally, only a single engine can actively scan a system at a given time. Using multiple engines simultaneously can result in conflicts that lead to system freezes and application failures. However, a number of security applications and application suites have optimized multiple engines to work together.

In short, Symantec Norton Antivirus will scan Avast Antivirus’s processes while Avast tries to scan Norton’s processes this will cause an endless loop of scanning as both will continuously scan each other, thus consuming unnecessary resources by out-scanning each other. Running multiple antivirus is not a wise thing to do, not impossible but unwise. Some people feel safer with 2 antiviruses instead of 1, but they are not aware that installing multiple antiviruses will cause the laptop or computer to freeze randomly, if not, Windows will lag badly.

Hundreds of thousands of malware, trojans, and viruses are released to the world wide web on a daily or hourly basis. Even the best antivirus engines available today can only detect so much from the time new threats are released up to a day, a week, or even a month after. This is where a multi engine antivirus becomes popular with the FBI, CIA, and big corporations, they are the best antivirus protection.

5. herdProtect

Free | 68 Antivirus Engines


[ Discontinued ] herdProtect Anti-Malware Scanner is a fast and free Windows desktop program which detects malicious threats, spyware and adware by utilizing 68 industry anti-malware scanners. It has no impact on your system resources and uses the herdProtect cloud-based scanning engine. The scanner is a second line of defense and is designed to work perfectly with your existing anti-virus software (we highly recommend you use another anti-malware product with herdProtect).

The scanner works by taking a snapshot of all the ‘active’ files on a user’s PC. They generally define an active file as one that is currently executing on the system or has the ability to automatically execute by means of an auto-start procedure (such as an extension, task, etc.). This snapshot is stripped of any personally identifiable details to make sure that the report is 100% anonymous and securely sent to the herdProtect servers to be analyzed. Upon arriving, the system quickly sorts the files as known or unknown entities. Known entities are then categorized based on the detections that were discovered when scanned by all 68 anti-malware engines. Engines that Power herdProtect

    All the antiviruses listed here are very good except for one or two. The antivirus that come for free is not up to the mark.

    Useful information mentioned above for the people who are working digitally and need to keep safe their valuable data and systems. But who works as a professional like in offices or they’re for own professional so I suggest them to use a paid antivirus because it has a lot of features like, it protects from malicious software, malware, etc.

    Anti-Malware software is computer software used to prevent, detect and remove malicious software. Antivirus software development is very important because threating is increasing day by day, cybercrime is increasing day by day. Nowadays it becomes almost impossible to keep safe our data without an antivirus. Though an antivirus can not protect us 100% from malware, adware and malicious program instead of that it has become necessary to use the antivirus tool.

    Free antivirus with multiples engines was never a success before. But, now its really time to switch to antivirus with multiple engines. As now we all uses antivirus in our phone or other devices to keep data safely, in general or be in professional sector, so their is a huge need for protection. Thus, this kind of antivirus is really going to work for it.

    Your April 2022 update is still in need of updating.

    1) SecureAPlus recently rebranded/redesigned as CatchPulse with a few engines.

    2) HitmanPro has been owned for years by SurfRight — which has been owned almost as long by Sophos. Per hitmanpro.com (Feb. 2023), “HitmanPro leverages malware databases from four security labs, including SophosLabs…” Title says 3; outdated (2013?) screenshot shows 4; text mentions 2 (conflicting with picture (4-3+1=2), but also accurate about a decade ago); no mention of Sophos anywhere.

    3) VirScan.org is an Asian site offering online file metascans similar to VirusTotal or OPSWAT MetaDefender.

    4) VirusTotal and MetaDefender have browser extensions that can automatically/manually submit downloads for analysis. VT and MD also do URL/Domain/IP reputation checks (as do URLvoid/IPvoid and other sites).

    PS – Thanks for including a real last content update date. Many sites don’t bother or substitute a recent non-original-content change date just to boost SEO.
