Blah, blah, BLAH! AV is generally useless. You need to be proactive not reactive. Oh Em Gee! How!? Simple. Dont use Java, Flash, Silverlight, ActiveX, etc. Use a browser other than MSIE. Tech kiddies will parrot out Firefox is da bestest evar! Fine, just avoid IE. Opera is good. I prefer Chrome. Don't try & get free stuff / downloads. Careful with email images, links, & downloads. Same with major social media sites. Avast, AVG, Avira, Norton, etc etc ETC... Suck. They are reactive, barely effective, & give a false sense of security. Most are bloated & just slow down your system for little gain/protection. We could go on & on but to sum it up. Leaver Defender on there, use a better browser. School is out. The End.
