Windows 7, Ultimate, x64

Many web sites, if not all, are loaded very slowly. This happens with IE, Firefox and Safari.
Ping www.google.com, timed out.
Ping www.microsoft.com, time out.
A reboot would make web browsing and ping command become normal. But this only last for a few minutes.

In Safe Mode with Network Connection, same problem!

Scanned the PC with Microsoft Essentials, Malwarebytes and Hitman Pro, nothing was found.

Tested the internet speed when browsing was slow, download speed is 100mbps, upload speed is 5mbps. This is what we bought, so the test results are normal.

There is another PC (Win8) behind the same router. It does not have this problem.

Any thoughts??

Thanks
Jack

Did you try http://www.microsoft.com/security/pc-security/malware-removal.aspx

And run the long version, it should take at least 3 to 4 hours or more.

Also try the Microsoft Safety Scanner from safety.live.com
Avast Free, Malwarebytes Antirootkit, and TDSSkiller (Kapsersky)  Make sure you are running full scans on each.
Cannot hurt to defrag and run ccleaner.
If nothing helps, check with HDTune.com free version and check the SMART for reallocated sectors.  Could just be a failing HDD.
