Hi, did you update the virus definitions before you ran the scan ?
how much free space do you have ?
what operating system and how much memory do you have ?
A system can run slower if you dont have much memory and its using a page file on disk. This is worsened if your disk is low on space and its fragmented. That should not however slow down the internet to the point that you describe.
