They don’t stop trying do they? I’ve just had a report about another new rogue that goes by the name of MalwareCrush.
MalwareCrush is a rogue anti-spyware program that uses aggressive advertising and is installed onto your computer through the use of Trojans and other malware. This software is typically installed on your computer when you download programs masquerading as a video codecs required to view a video on a web page. In reality, though, when you install these Trojans, they will instead show fake security alerts in your Windows taskbar and install MalwareCrush onto your computer without your consent.
Once MalwareCrush is installed, it will automatically start and scan your computer. When the scan is finished it will have found the malware that actually installed it in the first place, but will require you to purchase the software before you can attempt to remove it. This is obviously a scam and you should not purchase the software under any circumstances.
