The Internet Security and Total Protection editions of McAfee impart to your computer a wide range of protection from harmful viruses, spyware and malware. The antivirus software blocks pop-ups and spam, and shields your computer from network threats. McAfee also has a parental control system to keep children away from certain websites, but sometimes the software's settings can inadvertently block content on the Web.
A common content blocking problem with McAfee antivirus software is not being able to see websites correctly because the software blocks images. When you enable the program's content blocking feature, some image files on websites will not completely load or the McAfee program blocks the images. The McAfee logo will appear on the page in place of images and website logos. This common error can occur even if you log in as an administrator and type in your password for approval.
Pop-ups can be annoying and malicious software such as adware and spyware use pop-ups. However, you may have times when you need to enable pop-up windows while accessing certain websites. This also can include online games, chat rooms and live chat support from online customer service representatives. To disable pop-up blocking, launch McAfee and click "Options" at the top of the program. Click on "Block Ads" and deselect "Block Pop-Ups on this computer."
Blocking Legitimate Emails
McAfee prevents you from downloading attachments or providing sensitive information so that you and your computer are not susceptible to viruses, phishing scams, spam and other online threats. The McAfee spam blocker feature can sometimes place legitimate e-mail messages into the spam folder instead of your inbox. You can usually add trusted senders to your contacts list to resolve this content filtering problem.
Limited or No Internet Access
McAfee may limit Internet connectivity or completely block your access to the Internet. You will see a LAN icon with an exclamation mark on the taskbar. The McAfee firewall settings may block your connection to the Web. Double-click the McAfee icon in your taskbar and click on "Web and Email Protection." Click on "Firewall" and click "Restore Defaults." This error can also happen if you have another antivirus installed on your computer and both programs run simultaneously. If this is the case, you need to uninstall one of these antivirus programs.
