A virus can cause a laptop to be slow, but many things can cause your laptop to be slow and sluggish. Viruses will usually cause things like programs to just disappear, or applications stating that you don't have privaleges to run that application. Viruses can stop application from running, It sounds like your laptop needs a cleanup, or your hard-drive could be going bad. You may also have trouble with Registry and memory. I would look for a program that cleans your registry and defrags your files and memory. Maybe a clean install of your operating system and reload all your programs can have your laptop running like new again!
