Hello all. Basically, i've been getting pop-ups that my popup blockers doesn't block, so they are coming from within my computer. Some of the popups are the notorious winfixer, along with other things more recently. Also, sometimes my taskbar (the small bar at the bottom of the screen) disappears for about 10 seconds, and then comes back, which is quite strange. Also, sometimes when switching between windows on the internet, they become inactive, and no amount of clicking on a window does anything for 20-30 seconds. I have run Ad-Aware, the latest version, Spybot, and even Spyware Blaster, and all have detected nothing on my system. I can't seem to find where the problems are originating. I am running on Windows XP, with SP 2, on quite a competant computer. Can anyone help me in solving my strange problems, either by pointing me to a comprehensive guide, or by posting an answer. I have no problem posting a HijackThis log, if necessary.
