McAfee Internet Security 2013 ($40 for one year of protection on up to 3 computers, as of 12/19/12) didn't manage top marks in our security suite tests, but it's still a fairly proficient antimalware program that will keep you relatively well-protected. This security suite, which boasts a simple user interface and a super quick installation process, scans your system quickly and efficiently.
However, McAfee's uninspired design and average performance makes it a less attractive choice compared to its competition.
In our real-world attack test, McAfee was able to completely block 94.4 percent of attacks. Unfortunately, this means that it did let through 5.6 percent of attacks, allowing our test system to get infected. This test indicates how well a product will be able to block brand new malware attacks as it encounters them in the wild--and of the nine security suites we tested, only two let such a largepercentage through.
