This started with my password box being pre-filled. It took a long time to keep clicking "enter" and trying delete and backspace keys before I would get the "did you forget your password" notice. Then I was able to enter my password. It got progressively worse as even the search boxes on Firefox and IE were filled in by forward slashes. Then my separate e-mail client inherited the problem.
I run Zone Alarm, AVG free edition, Malwarebytes. None showed any viruses or malware. I ran CCCleaner and that didn't cure the problem. After reading the "how tos" on here, I used Spywareblaster which found one registry problem and removed it. I can now type in all input fields (except for password logon) without getting runaway slashes being entered. I also have a "Hijackthis" log file on this.
A couple times when I rebooted, my network connections didn't show up until I rebooted again. Can you help?
