Recently, I came across this virus on a system running MS Security Essentials. It appears to be a very problematic virus, which exploits a Java vulnerability (what I've read so far).
However, during my search, the only information I could find specific to this virus was information on how to remove it; not how to prevent it using existing products today.
The system ran MS Securty Essentials; current verion, current virus patterns, and the product did not even detect that it was inbound or had been planted (this even though "real time" protection was turned on.)
Why wasn't this virus detected? Why wasn't MS Security Essentials able to remove it? Why wasn't the target web site a known problem site, and access to it blocked either by MS Security Essentials or the MS Firewall?
MS Security Shall remain the product of choice; simply because it appears to be as good as any other product out there, AND it integrates seemlessly with Win 7 (and other verisons.) It operates effectively with a smaller footprint than other products as well, without significant impact to system resources.
Yet, here is a known virus; with a known payload; with a known lockdown of the system preventing further actions; so how was the virus able to penatrate the system?
Thank you for any insight and guidance provided.
