After several years of tranquility with AVAST (free), I followed the advice "forums" and bought Kaspersky 2014. From the first installation attempt from the CDROM, I had a monster mess on my PC (Toshiba), which I took several weeks to extricate myself, attempted reinstalled impossible with incomprehensible instructions from Kaspersky support. .. This morning I reinstall AVAST Version 2014 (always free), and all is well: ultra quick scan over etc ... Quiet for a year! I must not be formatted for paid antivirus, but I will survive! The passage of time, it is too late to turn this crap at Amazon, and I am of my 20 Euros! A forgotten. Here I am going to see "The Hunt of the Red October"; history to relax, and to reconcile with "the Russians" !!
