laptor running slow and not letting me in to some sites

That does sound like a virus or similar. Do you have any AV software, and what does a scan show? The virus/trojan may also have corrupted your Hosts file, or changed your networking setup.

Your options are probably:-
1 Take a backup of any documents/photos etc that you want to keep. Reformat the HDD and re-install Windows and all your programs.
or 2 Call in a professional

3) download Spybot & do a check of your system for spyware/adware or other malicious junk that is running.

4) clean the registry. download a program called "regseeker" & run it

5) visit the PC Pitstop website & do a check on your PC.

6) run MSCONFIG (type "MSCONFIG" into the "Run" box) & deselect the programs you don't use or don't want to load in at start-up (such as Winamp or Quicktime updaters), that way they won't load in & run in the background when you bot your PC up. DO NOT DESELECT YOUR FIREWALL, ANTIVIRUS OR EXPLORERE.EXE

The sites that you can't get into: are they 'secure' sites such as online banking etc (ie do their web address start with https?

If so then visit here and follow the instructions.
