A Windows 7 Pro 64 computer suddenly is running slowly re: opening programs AND will not open any page using any browser.
Have scanned for malware using a very good set of tools - nothing found. This seems like a very clean computer and there is every reason to believe it would be.
Have run various repairs to no avail.
Although I did find the hosts file empty - (does that really matter?)
Can't open the router GUI interface at 192.168.1.1 even!!
DNS seems to be working if one does a ping.
But can't open with a browser www.google.com www.yahoo.com
Also, I see that many programs don't open nearly as quickly as normal. It takes a long time for them to open. That's odd.
The HD tests fine with good transfer speeds as well.
Running sfc now....
