Set Up the Firewall

Learn to set your firewall settings in Windows.


Click Start, then choose Control Panel from the list.

If the All Programs list displays and gets in the way, move your cursor off the area, then try again. It's best to go straight up from the Start button then over to Control Panel to avoid this.


For Windows 7:

In the search box, enter firewall, then click Windows Firewall. Click Turn on Windows Firewall.

For Windows Vista and XP:

Find the Windows Firewall icon and click it. Under the General tab, click On (Recommended) or Off.

Do not turn off the firewall unless you have a firewall installed from another program. Turning off the firewall could make your computer or network more vulnerable to computer viruses and information thieves.


Click OK.

Scan For Viruses Using Windows Defender in Windows 7

Learn to scan for viruses in Windows 7.

Click the Start button at the bottom left of your PC screen, then click Windows Defender.

Click the arrow next to the Scan button, then click Full Scan. You can also choose Custom Scan to check only certain folders or drives on your PC.
