Browser redirect viruses, like Captchaone.Azurewebsites.net, are a family of viruses responsible for replacing the search results of your browser with their own. Whatever your preferred search engine maybe the Captchaone.Azurewebsites.net redirect virus will replace it. Likewise instead of receiving normal results on your searches you will receive a mixed batch of useless spam and Ads. These replacement search engines are a very poor replacement for Google/Bing/Yahoo. Their sole purpose is to display the Ads you see on your screen and this can make browsing extremely frustrating, not to mention the danger from visiting a dangerous web page through the Ads. We highly recommend that you uninstall the Browser redirect virus from your computer as soon as possible.
Is Captchaone.Azurewebsites.net Safe?
The main reason for the existence of the redirect viruses, like Captchaone.Azurewebsites.net or Pakfn.co.in ,is online traffic and the money it generates. Basically all search engines rate pages that are frequently visited higher then those that are not. Site owners want to be shown on the highest page of the search as possible and so all traffic is helpful to them. A redirect virus will spawn links of affiliated sites on hundreds of thousands infected computers. Even if a few percent of those redirected Ads are clicked on the creator of the virus will get considerable payment for his efforts from the sites that have been accessed via the links.
Google and Bing display Ads too, like the Captchaone.Azurewebsites.net virus, but those Ads are well regulated and immediately taken down if found to contain malware or scams. This also means that Ads shown by redirect viruses, like Captchaone.Azurewebsites.net, are much more dangerous and often used by virus makers to spread their “children”. Sites that display dangerous Ads are quickly blacklisted and you are given a warning if you try to visit one of them if using a normal search engine. With the redirect virus installed you are on your own. Since these types of viruses exist to spam your computer with Ads it makes sense to show you the most relevant Ads to your interests. To do that these viruses will spam your online activity and filter the appropriate Ads based on your interests. This data can also be send to the remote host of the virus creator and sold out to other hackers! This is one example of how your email may get into some kind of spam list.
What is Captchaone.Azurewebsites.net?
Whenever a Captchaone.Azurewebsites.net redirection occurs a new tab will be opened containing the virus featured content. Google redirect viruses are by far the most common ones, but Bing, Yahoo and Ask also have their own variations. Sometimes redirect viruses, like Captchaone.Azurewebsites.net, a specifically tooled to target a particular browser and due to Google Chrome’s popularity it is the most common victim. A Chrome redirect virus is actually contained within the browser itself as an add-on installation. This gives it a large control over the functionality of Chrome. A redirect virus can also change your home page and it will definitely mess with the default search engine. These changes are usually applied via a script and they cannot be removed manually as the virus simply sets them back automatically on every browser restart.
Due to their close interaction with your browser redirect viruses, like Captchaone.Azurewebsites.net Pop-ups are usually viewed as high level threats. A Chrome redirect virus can display all kinds of Ads that may look like system related messages on your screen. These are always fake and they aim to instill some kind of urgency into you. The problems they report are either exaggerated or non-existent, but the software recommended to fix these problems is actually either useless bloatware or rigged with a virus. When you are browsing and see some kind of system error message or Captchaone.Azurewebsites.net Pop-up try to close Chrome/Firefox first. If the problem is not real, but created by a Chrome redirect virus the message should go away when your browser is closed. Don’t attempt to download any software related to that message, but focus your efforts on finding the virus instead. Similarly there are a number of other fake issues that can be caused by the redirect virus:
- Missing plug-ins, video players, codecs and the like. If you’ve had no problem seeing videos online and suddenly you see messages claiming the contrary then the cause is the redirect virus.
- Tab redirects sometimes try to make you download different executable programs directly. Often these will trigger when you attempt to download something from a site yourself. Be very careful as these contain the worst viruses inside.
- Different type of “online scanners” can be used by the redirect virus in order to confuse you. These “scanners” will claim to have searched your computer for free and found problems (viruses, errors etc). This is just a scam – a scanner can never scan your computer without you giving it permission to do so first.
- Fake lotteries, polls and programs updates are also frequently exploited. You’ll get a message that your Java/Flash/other program needs an update. That update will contain the virus. The lotteries and questionnaires will require you to download and install some file to complete installing the virus in much the same way as the update scam.
Captchaone.Azurewebsites.net on Chrome
Like most malicious applications Captchaone.Azurewebsites.net on Chrome come from infected executable files. These can be obtained from a multitude of sources, but we have compiled a short list of the most common ones you are most likely to encounter:
- Software bundle installers. These are actually installers for other programs, but they carry addition programs inside that will also get installed as long as the Default installation option is selected. Because of this we advice all of our readers never to use Default – go for Advanced instead. It takes only a couple of extra seconds and mouse clicks, but while you do them you get to see a detailed list of all the programs and features that will get installed. Remove any additional software from this list even if it looks innocent enough – you can never know for certain if there is a virus inside.
- Email attachments bombs – it’s a very old, but still very effective tricks. The latest hit is to spam emails that look well written and appear to be work related. They will contain some file like Invoice.exe or Report.exe or whatever work related file you can think of. Be wary of the .exe file extension, because .exe is an extension assigned to programs /and viruses/ and office files are never .exe. NEVER download and install .exe files unless you are sure they are safe!
- Torrent and online storage sites are a cesspool of viruses. Any executable file downloaded from a torrent site can carry a virus. Sometimes these also have multiple download buttons spread around the page and only one of these (if any) will be real. Clicking on a fake button will also result in a file download, but this file will be a virus and not the file you want!
Some threats reinstall themselves if you don't delete their core files. We recommend downloading SpyHunter to remove harmful programs for you. This may save you hours and ensure you don't harm your system by deleting the wrong files.
