What's the latest best security/program (McAfee/Symantec/Norton/other) for PCs with Windows XP. Prefer Mozilla Firefox as browser, AND Internet Explorer.
What is the best security/protection program (McAfee/Symantec/Norton/other) for my Dell PC which has Windows XP. I prefer Mozilla Firefox as my browser, but also use Internet Explorer. I just want to know if Mozilla Firefox has identified an ideal product to detect and destroy spam, worms, add-ons -- eliminate security threats of all kinds... AND is tolerated by BOTH Mozilla Firefox AND Internet Explorer.
