This means "no text" to regular forum post readers. So your post may have been missed. You may want to re-post with a note saying your post got messed up. Use a subject like "Vista laptop been hecked??? Bad Lag Symptom".

As to your laptop problem, "Am i being attack by viruses or anything like that?", I would add program/s going update rampage(out of control)to your list of possible problems. What is the last update done or program added? I did a firewall update once that crashed my computer. Try and find out what is eating up the CPU usage, try this post for how to see what is going on, step 4.
