I used Mcaffe without any problem, but I heard that NOD32 was the best, so I unistalled it and installed an evaluation version of NOD 32 XP. Since then I can´t use Internet ( I can stablish connection, but I can´t navigate nor download anything nor read my email, nor update my antivirus ). This has happened to me in 2 PCs, first a Pentium 3 XP SP 1 and later in a Pentium 4 XP SP 2. Finally, I unistalled it and returned to Mcafee. Has anybody any solution, please ? Thaks.
