I'm using Windows 7 and on top of it I have installed Visual Studio 2010 and SQL server.
For some time now I have been experiencing a laggy behavior. Explorer windows minimize and maximize with a lag; the mouse pointer also moves slowly.
The question is: How can I detect if it's a malware or some corrupt registry setting that is causing the lag? It's a 3 GHz processor with 4GB RAM and a 500GB HDD.
here is a screen shot of my windows experience index
It almost feels like somebody has accessed my PC for monitoring. I'm on an office Domain, so this could be expected from the boss – though it's not officially told and I highly doubt that it is the case because I've been working here for 1 year now.
