I'm sorry to see my posting about the installation / uninstallation of Avast removed from the forum. Or rather, I'm sorry about a reason I might have given for the removal of the topic. I seems to me an important topic in terms of getting the most out of Avast. The issue is that while programs such as Kaspersky, Norton, Avira, Microsoft Security Essentials and others will automatically refuse to install with remnants of another anti-virus program still lurking in the computer, I have managed to install Avast despite the same remnants. This happened in the past, some time before Avast 7 was released. Some anti-virus programs will actually remove the remnants, on request, in stead of just refusing to install itself until you have removed the remnants yourself, using an uninstaller tool provided by your old anti-virus program provider. Because such remnants impede the installation of a new anti-virus program, my impression was that Avast allows the inadviseable installation so as not to lose the potential customer. What is the answer to this? Getting an informed answer will build confidence in Avast and prevent Avast from being affected by possible alien AV remnants still active in some computers.
