Hi, I have read through several threads where users have similar issues: a clicking sound in the background, iexplore.exe in the task manager that I can't kill, IE pop-ups (I use Chrome) and random audio ads without pop-ups. I was switching from AVG to Avast and picked up some malware in the few minutes that my computer was unprotected. I've uninstalled Java & Adobe, as I read that those can be vulnerabilities. I'm running XP SP3, and I thought it was fully updated but it is now asking me to download updates that I am pretty sure I already had. I have an installation of Linux on a separate partition of my C drive and a bootloader menu (GRUB) that allows me to select my OS when I boot up. I installed this because I thought it would be interesting to mess with Linux, but I haven't used it in months. The bootloader is still around, though. (not sure if this will show up on the logs, so hopefully this will clear up any confusion.) I've run the six steps, and all logs will be pasted in my next post(s). Thanks in advance for any help you can give me.
