I have just had some amazing help from Satchfan on the malware forum which has determined that i definitely have no malware on my system. However my problem remains and i have been directed to this forum.
My web browsing has become very very slow when I switch or reload pages. When i open task manager CPU is running at 100% which slowly reduces but still remains over 70%. Desktop windows manager seems to be running at 50% of CPU but the other tasks do not seem to add up to 100% of even 70%. A simlar picture is true when i open resource manager with CPU at 100% but with DWM running at around 25 of CPU. Can anyone help!
