Ooops. Something's missing from your post.
For now try a few of the posts about KEY LOGGERS and "SLOW PC" from our forums.
I have a Window Xp home PC not a laptop. It's a few years old, the last few months sometime I will type in a command the PC will not do anything untill 5 to 20 sec. Sometimes what you type want type out on the screen until after that 5 to 20 sec. I have dsl roadrunner lite which is fast usually it is instant as far as reconizing a command. Rebooting does not help. Once I did a extra scan with norton antivirus and everyting was cleared up for a day. Is there a maintinace program I can put through my PC or do I need to try something else.
