UP is installed when you install AVG antivirus. According to the Chrome Web Store, it has nearly 1. AVGs official description of the extension says it will warn you of unsafe search results. Back in December, Google employed security researcher Tavis Ormandy discovered that the extension adds a large number of new Java. Script APIs to Chrome when its installed and that many of the APIs are broken. Aside from exposing your entire browsing history to any website you visit, the extension offered many security holes for websites to easily execute arbitrary code on any computer with the extension installed. My concern is that your security software is disabling web security for 9 million Chrome users, apparently so that you can hijack search settings and the new tab page, he wrote to AVG. I hope the severity of this issue is clear to you, fixing it should be your highest priority. Four days after it was reported, AVG had a patch. As Ormandy wrote AVG submitted an extension with a fix, but the fix was obviously incorrect. He had to provide instructions for how to fix this flaw, and AVG issued an updated patch a day later. The fix restricts the functions to two specific AVG domains, but, as Ormandy noted, the websites on those domains have their own flaws that opens users up to attack. Not only did AVG ship a browser extension with obviously broken, shoddy, insecure code, but AVGs developers couldnt even fix the problem without having their hands held by a Google security researcher. Hopefully, the browser extensions are being developed by a different team and the real experts are working on the antivirus software itselfbut thats a good example of how those antivirus browser extensions can go from useless to harmful. Example 2 Mc. Afee and Norton Dont Think Microsoft Edge Is Secure Because It Doesnt Support Their Add OnIf youve been following the development of Microsoft Edge for Windows 1. Internet Explorer. It runs in a sandbox and abandons support for old, insecure plug in technologies like Active. X. It has a more streamlined codebase and a variety of other improvements, such as protection against binary injection, where other programs inject code into the Microsoft Edge process. And yet, Mc. Afeewhich is even installed by default on many new Windows 1. PCsreally doesnt want you to use Microsoft Edge. Best Free Internet Radio Broadcasting Software. Instead, Mc. Afee recommends you use Internet Explorer, and will helpfully remove Edge from your taskbar and pin Internet Explorer there if you let it. All so you can keep using the Mc. Afee browser extension. Even if that browser extension helped keep you secure a little bitsomething we dont really believeyoud be much better off with the improved security in Microsoft Edge. Norton does something similar, recommending you use a supported browser like Internet Explorer on Windows 1. Thankfully, Microsoft Edge will soon support Chrome style browser extensions. And when it does, Mc. Afee and Norton can force their browser extensions on Edge users and stop redirecting them to the old and out of date IE. Example 3 Avasts Online Security Extension Once Included Ads and Tracking. Heres one weve covered before Avast installs an Avast Online Security browser extension when you install the main security suite, and they later added a feature named Safe. Price to the extension in an update. This feature was enabled by default, and it displayed online shopping recommendationsin other words, ads that presumably make Avast money when you click themas you browse. To do this, it assigned you a unique tracking ID and sent every single web page you visited to Avasts servers, associated with that unique ID. In other words, Avast tracked all your web browsing and used it to show ads. Ben 10 Alien Swarm Games Pc. Thankfully, Avast eventually removed Safe. Price from its main browser extension. But antivirus companies clearly see their security extensions as an opportunity to dig deep into the browser and show you ads or product recommendations, not just a way to keep you secure. Its Not Just Browser Extensions You Should Disable Other Browser Integrations, Too. Extensions are just part of the problem. Any form of browser integration can create security holes. Antivirus programs often want to monitor all your network traffic and inspect it, but they cant normally see whats happening inside an encrypted connection, like the one you use to access your email, or bank, or Facebook. After all, thats the point of encryptionto keep that traffic private. To get around this limitation, some antivirus programs effectively perform a man in the middle attack so they can monitor whats actually going on over an encrypted connection. These work an awful lot like Superfish, replacing certificates with the antiviruss own. The Malware. Bytes blog explained avasts behavior here. Xbox Gamertag Finder Email. This feature is generally just an option in the antivirus program itself, and not part of a browser extension, but its worth discussing all the same. For example, Avasts SSL interception code contained an easily exploitable security hole that could be used by a malicious server. At least get an intern to skim your code before shipping it, tweeted Ormandy after discovering the problem. Its one of those bugs that Avast, a security company, should have caught before shipping it to users. As he argued in following tweets, this sort of man in the middle code just adds more attack surface to the browser, giving malicious sites another way to attack you. Even if the developers of your security program are more careful, features that tamper with your browser are a lot of risk for not much reward. Your browser already contains anti malware and anti phishing features, and search engines like Google and Bing already attempt to identify dangerous websites and avoid sending you there. You Dont Need These Features, So Disable Them. Heres the thing even barring the above issues, these browser extensions are still unnecessary. Most of these antivirus products promise to make you more secure online by blocking bad websites, and identifying bad search results. But search engines like Google already do this by default, and phishing and malware page filters are built into Google Chrome, Mozilla Firefox, and Microsofts web browsers. Your browser can handle itself. So whatever antivirus program you use, dont install the browser extension. If you already installed it or werent given a choice many install their extensions by default, visit the Extensions, Add ons, or Plug ins page in your web browser and disable any extensions associated with your security suite. If your antivirus program has some sort of browser integration that breaks the way basic SSL encryption is supposed to work, you should probably disable that feature too. Interestingly enough, Ormandywhos found a variety of security holes in many, many different antivirus programsends up recommending Microsofts Windows Defender, stating that its not a complete mess and has a reasonably competent security team. While Windows Defender certainly has its flaws, at least it doesnt attempt to insert itself into the browser with these additional features. Antivirus and Internet Security Solutions.
