computer virus?

for first step if you couldn't go to any website.. try another browser like Firefox..

then try antivirus

Download the programs linked below. Install them. Update them. Scan your pc with them, and do so weekly.

If you have System Restore turned on, the Restore files may be infected, and trying to reinfect your pc. I turn off that feature, reboot to delete the files, then turn it on after a full system scan with AVG.

Turning off System Restore.

(right-click My Computer, Properties, System Restore tab, check the box to turn off System Restore on all drives.)

Restart your PC, and hold down the F8 key.

When you see the Boot Menu appear (black screen white letters), choose SAFE MODE.

Run a FULL SYSTEM SCAN with AVG.

You can heal or quarentine anything found.

Run CCleaner to delete all your Temp and Temporary Internet Files.

You can also run Spybot and AdAware while in Safe Mode. I suggest you do a full system scan. Get rid of anything they find.

To exit Safe Mode, just restart your PC normally.

Some REALLY great features of Spybot Search&Destroy: Its ability to help your PC block known spyware/hijacker sites with Immunize feature, a Secure Shredder for truly removing files from your PC, and Startup, which allows you to view the files starting with Windows.

CCleaner is a freeware system optimization and privacy tool. It removes unused files from your system - allowing Windows to run faster and freeing up valuable hard disk space.

Make sure Windows Updates and Java Updates are current.

Google the terms Vundo and Smitfraud infections.

Try Superantispyware.
