my computer suddenly has become very slow when starting any kind of "explorer" program.
if accesses the drive as shown by the hard drive light, then just "sits" for about 15 seconds
before doing anything else. When moving to another web page, it also takes about 15 seconds

I have scanned for spyware and removed everything found.
There is a program called "popupadzero" which I removed from the machine but still appears o
the bottom right tray. I have removed all occurances that I could find from the registry and searche
the entire drive for it but it still appears. I don't know if this is the problem or not

Any ideas would be appreciated, thank

Run an adware program such as Lavasoft. You can download it off the internet. The popupadzero is a problem so run a program like this and try to get rid of it.
