With mixed feelings I ordered some time ago McAfee VirusScan 10 on Amazon. So far I have always used Norton Internet Security, but I was from the latest version (Norton Internet Security 2005) pretty disappointed with the high resource consumption and the lack of support. Norton has prolonged the start times of programs on PC significantly and was partially worse than a virus. Therefore this time I have decided to use the second largest security experts McAfee. Many large companies worldwide rely on McAfee. After the restart at the end of the installation, I was eager to test the new antivirus software. I was absolutely thrilled !!! Even with the latest updates, I could make out only a very small additional resource consumption. When you start programs - almost no difference! My Conclusion: Significant performance benefits and at least equivalent guarantees for competitor Norton make this program in my opinion an absolute Bestseller
