First time ever, I think.
I practice safe computing. I keep my anti-virus software up to date. If my browser warns me that a certain web site is dangerous, I stay away.
But I got a virus anyway, or at least a bad case of adware. Despite backing up gigs and gigs of personal videos, I'm still told that there's 0 MB of free space on my hard drive. Despite my adblocker software, ads from one particular source now show up on just about every web page. Sometimes even new tabs will open in my browser.
Computer's been off all day, I have an appt at Best Buy tomorrow to get it cleaned up. Posting this from the Chromebook right now.
Somehow I'll survive....
