Please disregard, sorry. I got through it on my own, eventually. This thread can be closed or deleted (I'd do it, but can't figure out how.)
Windows XP machine, running IE8.
I started noticing when entering a Google search in the search box in the upper right corner of IE8, the window immediately closes. I can search Google by going to www.google.com, but sometimes that results in redirects.
IE8 also closes randomly during other, non-Google activity.
I use Symantec Endpoint Protection for A/V (corporate-installed) and the "green dot" on the shield in the tray icon no longer shows up -- just the shield with no dot. (Presumably SEP is partially disabled.)
I have run Malwarebytes Anti-Rootkit - it removed four items - 1 dll file and 3 registry entries, but I still have the issues described above.
I ran Malwarebyes Anti-Malware - it found no threats.
I ran TDSSKiller.exe - it removed one threat, but yet I still have the issues.
Any advice on what to try next would be greatly appreciated!
