How to Remove Antivirus Protection Trial (Uninstall Guide)

Tell your friends:
Antivirus Protection Trial is a rogue anti-virus application that reports non-existent infections on your computer. This scareware pretends to scan your computer and find files that are infected, but of course, it's all a lie. It also gives you loads of fake security alerts. The rogue application blocks you from running malware removal tools. Antivirus Protection hijacks web browsers and changes LAN settings and configures your computer to use a proxy server that displays a fake security warning instead of requested website. The rogue program may also randomly open web pages containing explicit/adult content. You are only allowed to go to the Antivirus Protection website to buy their software to remove the threats which do not even exist. Those websites are protection-soft24.com and aviraprotect.com but there might be more.



Antivirus Protection Trial will hijack your web browsers and display fake security warnings. Here's a screenshot of what the fake Internet Explorer warning looks like:



It will also display fake security warnings and alerts every one minute or so. Just like this one which states that your computer is being attacked from a remote machine:



Other fake security alerts:




Here's a screenshot of what the protection-soft24.com (payment page) looks like:
