Tricking Vista's UAC To Hide Malware
Vista's User Account Control, love it or hate it, represents a barrier against unwanted software getting run on users' computers. A Symantec researcher has found a simple way to spoof UAC and says that it shouldn't be completely trusted. The trick is to disguise the UAC warning dialog in the color associated with alerts generated by Windows itself.
Having to click through 3 different prompts in order to delete a file was enough for me to disable UAC. It lasted about 2 days on my computer.
