I have been criticized for believing in invisible malware even though I have posted links supporting this as far back as 12/12. Even 2old will probably get it if he takes time to read the link that I know he will. No offence 2old I just like to stir the pot too and you have taken enough cheap shots at me. I apologize in advance. Below is the best article I have read so far on 'invisible malware' or unscannable malware. The video at the bottom is a must. You see code, you see a function scrambel the code then you see several scrambles more scrables each scramble looks nothing like the others then the garbage is executed and it works fine. Traditional AV scanners have no hope of detecting this new plague. server-side-polymorphism-malware by sophos This is why most malware infections are all done from web servers. The attacks are mainly in the form of links. If you click on the link you are infected. Infected adds and infected legit web pages also will infect you using hidden injection frames/ports. There has been a massive increase into website getting hacked through a varity of processes. Sorry I cut and pasted the link. I was at work and the only allowed browser would not allow me to use the link button and it also 'truncated' some of the url in the middle of the url not at the end and I didn't catch it.
