The web browser, be it Chrome, Firefox or Safari, is the most virus-exposed program found on your computer. Every time you browse a site, the browser downloads data from the internet and brings it to the computer used.
Just click the wrong link and the browser will load a virus onto your PC, which will be ready to infect your computer without the antivirus having time to stop it.
It then becomes very easy, for malware creators, to hide scripts and viruses inside web pages and then make sure that the link spreads, via email, via Facebook and Twitter or even in forums and blogs.
These dangerous links are mostly present in torrent, piracy and adult content sites, where it's really easy to click on a malicious link or button, thinking it's the good one.
Those who have experience in the web and can surf carefully, should be able to recognize strange links and clicks to sites with viruses by eye.
Most people, on the other hand, are not prepared to find out where the trap is hiding and should really install an extension that protects the browser .
Personally, I'm not a fan of antivirus extensions, but having one that, on command, scans a link to check that it's safe before clicking it, can really come in handy.
In this article we see the best antivirus extensions for Chrome, Firefox, Safari and Internet Explorer browsers .
Some may already have an extension of this type installed if they use antivirus like AVG, Avast, Avira, Kaspersky or others because they include it in their protection package.
In general, it may be fine, in other cases, however, it is only a useless monitoring plugin to be deleted (such as AVG webTuneup to be removed).
1) VirusTotal for Chrome, Firefox and also Internet Explorer is the extension of the most famous online virus check site, virustotal.com.
Once installed, you can right click on each web link to find out what is hidden behind it and, above all, if there are no security risks.
The check is done with 66 different services and is therefore extremely reliable.
1BIS) Similar and with the function of checking the files downloaded with 30 antiviruses together, it is also OPSWAT File Security, for Chrome.
2) Microsoft's Windows Defender for Chrome, which protects against all malicious and dangerous sites by blocking them before loading.
3) WOT is an extension for Chrome, Firefox, Safari and Internet Explorer that marks sites in searches with a symbol, green, yellow or red, based on its reputation.
WOT (web Of trust) which is based on user reviews, may not be 100% accurate because it does not use any automatic scanning system, but it is excellent for knowing the degree of reliability of online shopping sites.
4) Secure Browsing, only for Chrome, is an extension that puts on the contextual menu that appears by pressing the right mouse button on a link so you can check it.
It works in a simple way and is very useful especially for checking file downloads, which are not viruses or malware.
Scanning is done with more than 60 different security services. including VirusTotal, Avira, BitDefender, Comodo Site Inspector and others.
5) Safe Preview to open links in preview is another extension for Chrome and also for Firefox that adds the option to the right mouse button when clicked on a web page.
In this case, a submenu opens with three options, one to check the link with 7 antivirus engines, one to open it and one to open it in incognito mode, without therefore storing data on the browser.
The extension also works to preview Google search results, to know immediately if a site is safe or harmful.
6) Dr.Web for Chrome and Norton Check links in Firefox are similar extensions for checking links on a page.
The antivirus for the browser is installed so you can scan any link by right clicking on it and choosing the Dr.Web option.
After checking, Dr.Web will open a page on his site with a green indication if the link is clean or red if he has found something wrong.
The only drawback is that Dr.WEB blocks a lot of website content by default, so some sites may not work or display properly.
7) BitDefender TrafficLight is an extension (Chrome, Firefox and Safari) to protect the browser from malware viruses and phishing attempts.
The extension is a bit heavy, but if you are afraid of using the internet for online purchases or checking your bank account, then it can be a strong and certainly reliable solution.
Who does not want to install anything, can certainly do it because all browsers still have an internal security system that, most of the time, preventively stops browsing on a dangerous site (for example we have seen how Chrome blocks dangerous download sites) .
