HTML:URL-inf[susp] is the detection name used by various antivirus engines. Primarily, that detection is often spectated by Avast product users. HTML:URL-inf means that the antivirus program has blocked the connection to the website that looked suspicious for it. However, that is not always the truth – false detections can trigger that alert as well.
What is HTML:URL-inf [Susp]?
It is quite easy to understand some of the details about this detection from its name. HTML:URL-inf states the fact that the detection is related to the Internet connection, and [susp] part means that this connection is suspicious. Avast, AVG, or Avira, which use this detection name, are not sure if the website has some malicious content. However, it decided to block access to the site. You can spectate this error even if the connection is established, nothing goes wrong, and you have opened some legit website, like Yahoo mail or so.
In the cases when the chosen website is legit, but the HTML:URL-inf detection is triggered, you likely see the false detection. This situation is pretty often the case when you use a free antivirus tool from the aforementioned vendors. The free license policy for Avast/Avira/AVG antiviruses states that you may use these programs for free, but it will lack some important elements. Those elements are database updates, updates to the heuristic engine, and minor updates containing bug fixes, for example.
Short description of the HTML:URL-inf detection:
|Appears||While browsing the Web as well as randomly|
|Possible reasons||Outdated anti-malware program, malware presence|
To remove possible virus infections, try to scan your PC
Without the regular updates of the detection database and heuristic engine, it is pretty easy to see that some of the legit programs on your PC are malicious. In fact, they don’t contain any portion of the malicious code, but outdated databases don’t think so. Things are even worse when we are talking about the heuristic engine. It can be triggered on literally everything when it is not set up. And the updates bring these settings to the heuristic module. Without them, you will constantly spectate things like HTML:URL-inf[susp] or IDP.Alexa.53 virus messages.
Is the HTML:URL-inf dangerous?
If you see the HTML:URL-inf message when opening the unknown site, you have likely nothing to worry about. Your anti-malware tool has stopped the potentially malicious stuff. But seeing the HTML:URL-inf and also seeing that nothing changes mean that your security tool has gone mad. To make things clear, and ensure that nothing threatens your computer, it is recommended to scan your computer with another antivirus tool. I can offer you GridinSoft Anti-Malware as one that will show you the accurate results, and stop the hazard in case it is really present.
There is the probability that HTML:URL-inf detection is caused by malware-related changes in your networking settings. A wide range of viruses modifies your HOSTS file or other setups that are responsible for background services work. In this case, the malicious connection is blocked, but the exact virus is not. It can conduct its activity as nothing has happened, so your computer is still in danger. Thus, you must check your PC for the possible presence of malware.
How dangerous are the sites?
Legitimate pages, like Twitter, Facebook, Google or so, are not dangerous at all. You can find some malicious content on these pages, but thanks to the heavy moderation of these things, it is very hard to find something that can harm you and your computer. But the Internet consists not only of legit and well-moderated pages.
The majority of antiviruses block the pages that contain malicious advertisements. Those banners have a malicious link inside, and only the crook who posted it knows where this link leads. Instead of redirecting to a really malicious page, this link may start the downloading of the unknown application, or redirect you to the exploit page. Such tools as RIG exploit kit are used exactly to inject malware through such redirects.
People often ignore the Internet as a source of various viruses. In fact, all malware is spread through the Internet, and it is stupid to deny it. Malware development increased tenfold in the 90s’ when people got easy access to the World-Wide Web. Well-designed anti-malware software usually has a network protection feature that blocks all possible malicious connections. But when your security tool shows you the HTML:URL-inf message after opening Yahoo – it is a pretty bad sign. That usually means that your antivirus tool has problems with correct detection, and possibly cannot detect the malicious pages.
How to get rid of the HTML:URL-inf detection?
Since this detection appears to be a false detection of the malicious site, the best way is to update your antivirus tool. It will likely get a patch that will solve the error that causes the appearance of HTML:URL-inf. But first of all, you must check if this detection is really false, or something has changed your networking settings and attempts to connect to its server.
The problem with Avast or Avira free antiviruses is that they do not have the removal function – they work as just scanners. With GridinSoft Anti-Malware you can either scan and delete the threats from your computer, and also prevent the opening of malicious pages. This anti-malware product has an On-Run Protection feature, as well as Online Protection. The joint action of these two will prevent any hazardous situations that may ever occur.
