I like to be proactive. So, i cruise though Blogs and Forums daily to see what is running wild out on the Wild Wild Web.
Some of the places i like to check are:
Bleeping Computer- Great Site with really solid information,Forum, Removal tools and Tutorials.
Bharath's Security Blog -Good site with what going around and helpful removal instructions.
TrendMicro - Good Antivirus program but also good for updates.
I got a bunch more but i gotta go now ...
