After years of my AV never finding anything, i've suddenly started getting Java exploits, Java trojan downloaders, etc. A scan a week ago picked up 2 files and just now a scan picked up 5. Has their been an increase in this activity, i'm using firefox with Security Essentials. (The weird thing is I posted a while ago that my AV never finds anything and I wish sometimes it picked up something just so I knew it was working, be careful what you wish for).
didn't firefox recently have an exploit with the java deployment toolkit 6.0.180.7.. here's a list of plugins to look out for https://www.mozilla.com/en-US/blocklist/
