I hate to tell you this, but almost no online virus scanner is of any use. Most of them are just trial versions of paid software, many of which can’t help you, and some of them are also phishing sites trying to steal your data or convince you to download malware.
Fortunately, there are some really useful online antivirus scanner free out there that allow you to clean up your computer incredibly quickly.
What is an online antivirus scanner?
It is a tool that allows you to upload files and check if they have viruses inside. This means that you can only check certain files, not the entire computer system.
While such websites can be convenient in certain circumstances, they cannot completely replace the antivirus software on the computer. They cannot protect you from many different types of computer viruses, nor can they fix files when a virus damages them. In addition, these tools can only check for known viruses. An online antivirus program cannot detect any suspicious behavior or any new threats at all.
Therefore, we recommend that you only use these online virus scanners when you need to check for any files that contain viruses or are unable to install antivirus programs on your computer for any of those reasons.
But if the reason you don’t install an antivirus program because of its price, you should consider the free options that world-famous antivirus companies offer. Of course, such programs will have some limited features, but they will give you better protection at no extra cost.
Avira also offers an online virus scanner. It’s based on the Avira virus scanner and works like an antivirus installed on your computer with only one difference – it only checks the files you upload, not the entire system.
You can also upload up to five files and their size should be less than 50MB. If you want to test a website, it also has an option that allows you to submit a suspicious URL.
This tool can detect malicious code, as it uses the Avira virus database, although it sometimes gives some false results.
Like Avira, this is also a tool that allows you to check viruses online for free for all uploaded files and suspicious websites. VirusTotal can check all file types under 256MB in size, even in ZIP and RAR formats. But you can’t do many scans at once, and sometimes it’s a bit inconvenient.
If you own an Android mobile device, you can also use this app to protect programs and check files or URLs that you think are suspicious. This tool is completely free to install and very easy to use.
What’s more, VirusTotal also offers Firefox, Chrome and Internet Explorer browser extensions that scan URLs and files before you proceed to download them. This is a handy tool that gives you some additional online device protection options. Of course, it cannot replace antivirus software installed directly on your computer, but they can work perfectly together.
Kaspersky also has an online virus scanner that supports both files and URLs. One file that you upload to this website may be larger than 50MB.
The interface of this website couldn’t be easier to use. You roll the link and choose the attached icon to upload a file. Press SCAN to start the antivirus process, the results will be displayed right after.
If there is a threat detected, Kaspersky VirusDesk will display “Threats detected in ” and display the file name and other relevant information. If your computer still works fine, you will see a message “No threats detected”.
This tool has a fairly simple interface and is easy to use. Just drag and drop the files you want to check and click “Analyze”. And the result will be displayed: If there is any threat, the user will see a red mark; If it is a clean file, you will see a green checkmark.
MetaDefender Cloud only allows uploading one file at a time and its size does not exceed 140MB. In addition to scanning files, MetaDefender Cloud can also check by IP address. So, if you cannot be sure that the web address you are going to visit is secure or not, MetaDefender Cloud can help you with this.
This tool performs file scanning and virus analysis based on more than 30 different virus databases provided by McAfee, Kaspersky, and AVG. This explains why MetaDefender Cloud can detect most viruses that were known before. In addition, it has a Chrome browser extension that checks downloaded files for viruses and provides users with some additional security features.
F-Secure Online Scanner is the fastest online virus scanner available on this list. It can also find the majority of malware and does not require installation on your computer.
Among the online virus checkers mentioned in this article, F-Secure Online Scanner is the easiest and easiest to use. You don’t need to select any file to scan, it will automatically check your entire computer system at an incredibly fast processing speed.
ESET Online Scanner is one of the free online antivirus tools with good efficiency. It has a fairly simple user interface to get started with. ESET Online Scanner also gives you options like full scan, quick scan or custom scan. Alternatively, you can also choose to delete any malicious files automatically.
With this online virus checker, you can check up to five files at once (each file should be less than 100MB in size). Jotti’s Malware Scan checks files against the databases of different antivirus vendors like Avast, Bitdefender, Eset, and several other well-known vendors.
However, the tool has one significant downside – you have to wait in line for a long time if too many people are looking to check their files – making it slow. In addition, it also has a pretty ugly interface and is not user-friendly.
All of the online virus scanning sites listed in this article are trustworthy and used to check for computer viruses and known malware. It will help you feel safe when extracting archive files or launching .exe file.
But these tools cannot completely help you stop online threats on the Internet. You should install more antivirus software on your computer to be able to handle this problem better.
Yes, you are not mistaken. Google also has an online antivirus program and you can scan your system files and then find an online copy of them from Google Chrome, and it works pretty well. Since this is one of the most popular web browsers, I believe your computer probably already has it installed.
To be able to use the free online virus scanning feature on Google Chrome, copy and paste chrome: // settings / cleanup in the address bar of your Chrome browser (remember it doesn’t work in a browser another web). Once the page has loaded, select Find and wait until the virus scan is completed.
