My website was injected with the script <strong>avg_ls_dom.js<\/strong> and I was very worried that my site could have been hacked. However, when I viewed source of some other sites, I also saw the script appear. There is no way this is a mass attack because I checked very popular websites and all of them are injected with the script also. I started to think that this is my computer&#8217;s problem and I was right.<!--more--><\/p>\n<p>This is actually a serious bug of the popular anti-virus program AVG 2011. In many cases, websites are flood with HTTP requests and they couldn&#8217;t be loaded properly, sometimes I even couldn&#8217;t access my website. The script is added to the header of all web pages and it look like this:<\/p>\n<p>[html]&lt;script type=&quot;text\/javascript&quot; src=&quot;\/A2EB891D63C8\/avg_ls_dom.js&quot;&gt;[\/html]<\/p>\n<p><strong>AVG<\/strong> is a great anti-virus software that I often recommend to my friends as it has both free and paid version. It has kept my computer safe and free from virus for years. I checked all of AVG components and it appears that the bug originates from the option <strong>Surf-Shield<\/strong> in the <strong>LinkScanner<\/strong> component. The Surf-Shield checks web pages in real time to identify malicious websites before you visit them, it would protect you completely by adding the script <em>avg_ls_dom.js<\/em>. The script then will report back to AVG to check links for you. It sounds like a good way to protect users when surfing, however, it could also affect users&#8217; experience seriously. Sometimes when a lot of users with AVG access a particular site, you could see its loading time take very long.<\/p>\n<p>If you can protect yourself from malicious links, you can fix the problem simply by disable the option <strong>Surf-Shield<\/strong>.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/www.techwalls.com\/wp-content\/uploads\/2011\/08\/linkscanner-avg-component.png\" alt=\"linkscanner-avg-component\" title=\"linkscanner-avg-component\" width=\"594\" height=\"432\" class=\"aligncenter size-full wp-image-337\" srcset=\"https:\/\/www.techwalls.com\/wp-content\/uploads\/2011\/08\/linkscanner-avg-component.png 594w, https:\/\/www.techwalls.com\/wp-content\/uploads\/2011\/08\/linkscanner-avg-component-300x218.png 300w\" sizes=\"auto, (max-width: 594px) 100vw, 594px\" \/><\/p>\n<p>If you had the same issue with AVG, do you have another solution to fix it?<\/p>\n","protected":false},"excerpt":{"rendered":"<p>A few days ago, I checked my blog&#8217;s HTML code and found out a serious issue.
