So I'm using Kaspersky Internet Security 2013 and Malwarebytes for virus/malware/adware/etc. detection and removal. According to both of these programs I don't have any viruses/malware/root-kits. So I am wondering why my Internet Explorer and Chrome become very slow after the pc has been on for four hours or more. The actual pc isn't slow, just the internet loading. If I reset the pc the internet runs quick again like it should. Should I reformat my hard drives or try something else? Below are my pc specs.
MB-Asus P8P67 Deluxe
CPU- Intel i7-2600k
Memory-16gb Corsair Vengeance LP
SSD-Sandisk Extreme 240gb
HD-Western Digital Caviar Black 1tb
GPU-EVGA GeForce GTX 680
PSU-Antec True Power Quattro 850w
Thanks for reading and I hope you guys can help me out here.
