A computer, especially one that is not protected by antivirus software, can be an easy target for malware. If you do not want to install a full-fledged firewall on your PC or want to get diagnostics from two different sources, try checking the system online (although in some cases you will have to install a small utility, but it weighs much less). Now we will tell you how to do this and analyze the most effective services.

Kaspersky Security Scan: a powerful online virus scanner
Kaspersky Lab offers its own version of online virus scanning. Previously, it was called “Security Scan”, but this year the project was closed, and its place was taken by Kaspersky Threat Intelligence Portal.
How to check your computer using it:
- Go to the verified website .
- Click “Select File” and find the one that arouses your suspicions.
- When it loads, click “Check”.
You can also scan a questionable web page address:
- Copy the link to it.
- Paste in the line “IP address, domain or web address”.
- Start checking.
As you understand, a deep scan of the entire system cannot be carried out in this way, but it can be used for preventive purposes, for example, to make sure that a downloaded program or document is safe.
Bitdefender Quickscan: Fast online virus scan of your PC
Some time ago, I also offered laptop and PC checking for free and via the Internet. It was carried out here – http://quickscan.bitdefender.com/, but now the service is not available. However, instead of this product, two others appeared (you can find them at the same address), which involve the installation of small utilities:
- Antivirus Free Edition is a super-light antivirus that installs instantly, does not consume PC resources and does not have unnecessary features that are difficult to manage.
- Home Scanner – monitors Wi-Fi, looks for vulnerabilities in the home network, prevents hacker attacks and password cracking, and also prevents other devices that support Smart Home technology from crashing. At the same time, it weighs a little.
Both products have an intuitive interface: all basic functions are guided and have an eye-catching design.
Eset Online Scanner: effective computer scan for viruses
This defender is really capable of scanning and cleaning your computer without downloading any additional software. It is enough to go here and click “Run”.
- Specify disks or storages to process.
- Wait for everything to be checked.
- Perform a virus cleanup.
To work, you do not need to create a profile in the system. Also, you don’t have to disable your main firewall – Eset doesn’t argue with it. At the same time, the product is no less attentive and effective than a full-fledged antivirus: for verification, it uses intelligent databases that are constantly updated with new types of viruses.
Panda Cloud Cleaner: Online Flash Scan for Viruses
A fairly well-known antivirus vendor also did not lag behind in terms of providing services and offers users as many as four types of a lightweight scanner:
- usual (with the installation of a small utility);
- without installation;
- to check USB devices;
- for a computer whose system no longer starts due to a critical infection by viruses.
Choose any ( https://www.pandasecurity.com/en-us/homeusers/cloud-cleaner/ ), run and follow the step by step instructions. First, check which files have fallen out of favor with the firewall because it will remove them. The program will self-destruct after verification, you do not have to look for the remaining elements.
F Secure Online Scanner: Virus Treatment and Spyware Stress
You can find it here . This online scanner offers to install the software, which takes just a few seconds, and after the procedure it disappears without a trace. On the site, you just need to click the Run now button. Firewall can:
- Search, treat and remove viruses, phishing and software, surveillance programs and data theft.
- Get along with an already installed protector from another firm.
- Carry out both scanning of the computer as a whole, and of specific folders, archives, documents.
And, of course, it’s completely free.
Virustotal
Service from Google for checking the computer exclusively online, without any installations. Knows how to identify, treat and remove viruses of any complexity, thanks to extensive databases.
- Check it out here: https://www.virustotal.com/gui/ .
- Select a file or site url.
- Start scanning.
- Wait a few minutes (if you close resource-intensive programs, things will go faster).
Unfortunately, a complete check of the entire system is not provided.
Dr. Web: effective file scanning for viruses
Dr. The Web is a very well-known brand from which one would expect a powerful enough resource to scan a computer. But, unfortunately, it also only works with individual files and addresses.
To use the service Dr. Web:
- Open http://online.drweb.com/ .
- Click Browse.
- Select a document.
- Start scanning.
These are, in fact, all the most popular online antiviruses that you can vouch for. Just go to their official sites, and not to the resources of intermediaries, so as not to become a victim of hunters for other people’s data.
