After installing Kaspersky 2011 Internet Security on three (3) computers there was a noticeable slowdown of the computers. Is this normal, I am thinking the AV is scanning everything incoming & outgoing therefore being slower.
Also depends on how much system memory is installed and what processor it has. Systems with only 512mb to 1gb of memory will slow you down with xp installed. You would need more than 2 gb for Vista and 7.
