On re-starting, which it did itself, it was extremely slow, and stayed that way for 2 or 3 hours. During that time I was informed my firewall was off (I hadn't turned it off, and it came back on by itself), and I noticed a few unusual processes running (cpu constantly between 70%-100%). These were:
drwatson - which told me a couple of times it was encountering a problem.
I also noticed various avg-related things, as if it was doing an automatic update, and the windows update icon on my system tray a couple of times. About an hour into all this (maybe a litle earlier) avg told me it had detected exploit.PDF, which it couldn't heal, and is currently in the virus vault.
I'm wondering if the windows update icon and slowness may explain why since this started I've lost over 1.5 gigs of hard drive space which I can't explain (clearing temporary files does nothing). I haven't been able to identify any new files to account for the memory.
The only particularly noticable symptom right now is IE misbehaving. About half the time I try to open a new tab it just says blank page, which it then doesn't let me close, and I have to close IE using task manager (also goes slow during this, and any IE activity with any waiting involved, including logging in here).
I ran mbam and it found no problems.
Thanks in advance for reading this.
