How to remove ERR_SPDY_PROTOCOL_ERROR

About this threat

The most probable reason ERR_SPDY_PROTOCOL_ERROR ads are showing up is because of an ad-supported software infection. This is a classic tech-support scam that tries to frighten users into calling certain numbers where they would be fooled into providing remote access to their operating system. If an ad-supported software is behind these ads, they will be interfering with your browsing constantly. An adware commonly installs during the freeware installation. Just to be clear, the adverts are rather harmless by themselves, and if you do not dial the number, no damage will be done. The reason calling them is not a wise idea is because they would try to scam you out of a lot of money, or some malicious software would be installed. You should never call the numbers in these questionable adverts, and you should be cautious about who you give remote access to your PC. And if you’re still concerned about the warning you are getting, it is false, and your system is secure. So as to make the alerts disappear, all you need to do is eliminate  ERR_SPDY_PROTOCOL_ERROR.

How does it behave

Since no one would knowingly install adware, it normally is distributed via free programs. If the software has something added, and you choose Default settings, you will not see it. Instead of Default, pick Advanced (Custom) settings. If you notice any items trying to install, unmark them. And if you feel they might be of use, remember that they didn’t intend to properly disclose their installation, and you would have unknowingly installed them. Pay close attention to what you install onto the system, and how you do it, unless you wish to regularly end up having to uninstall ERR_SPDY_PROTOCOL_ERROR or similar.

All of these kinds of alerts are the same, they all want to trick users into believing that their system is encountering some type of issues. Scammers will think of all kinds schemes, such as malevolent programs, licensing or system issues. It’s also common for the alert to include warnings about data loss or leaks since this makes users panic. A phone number would also be conveniently given, which would allegedly connect you to tech-support people who would repair the problem. Legitimate companies will never ask you to call them, so keep that in mind. For example, if Apple or Microsoft is asking you to call them, it’s definitely a scam attempt. These scammers would try to convince you that there is a lot wrong with your computer, and that they’re the only ones who can solve the issue, which of course, would cost you a lot. Quite a few users fall for these scams because they might be somewhat elaborate, which is why tech-support scams still exist. It isn’t hard to imagine why somebody may fall for these scams because if they’re popping up regularly, they might look pretty legitimate. If us claiming it is a scam not sufficient, you could easily make sure by using a search engine to look into it. Probably, the first few results will confirm that it’s a scam. So don’t pay any attention to the alerts and just deal with the problem. If the warnings are frequent, you will need to delete ERR_SPDY_PROTOCOL_ERROR ad-supported program to make them stop.
