For over a year we’ve been aware of an emerging security threat that targets (primarily) home PCs. But we’ve seen this security problem jump to corporate PCs as well. This threat is a serious problem as we’ve seen it show up in the field many times.
This threat shows up in the form of ‘Fake’ antivirus software – it’s usually inadvertently downloaded by someone casually browsing the web with Microsoft Internet Explorer – and alerts the user that “Your computer is infected” or “Your computer is not protected with antivirus software.” The graphics are very realistic and are designed to look like legitimate security software. The “software” (it’s actually spyware) can be called ‘Antivirus 2008,’ ‘Antivirus 2010,’ or ‘Antivirus Pro’ or some variant of those names.

Recently, we’ve seen the software become more convincing, and harder to remove. One variant of it literally locks up your operating system – holding it ransom (claiming that the entire OS is infected with viruses or spyware) until you pay to upgrade to a “Premium” version of the software. This “Premium” version “removes” these non-existant viruses.
“Fake Antivirus” software is somewhat difficult to remove, but it can be done — though it’s far easier to prevent it. While we’re finding that many popular antivirus packages won’t block it (because it uses many tricks to get around them) you can do a few things to keep it at bay:
