Some things to do, in this order....
==Download this temp file cleaner from http://www.atribune.org/ccount/click.php?id=1 --click in the download window to run it, and when ATF Cleaner opens go Select all, and then Empty Selected.
Next click Firefox [if you have that browser..] at the top, Select All again, and Empty Selected again. Follow that procedure also if you have Opera.
Close ATF. Run it in all other profiles, except for that new one...don't think of touching that one!
==Please use IE or Firefox to do an online scan at panda:- http://www.pandasecurity.com/homeusers/solutions/activescan/?
-for the free online virus scan select the link Scan your PC, then Register [otherwise there will be no disinfection, merely detection] with a valid email and follow through.
Please ATTACH to your post the log it produces.
==Download this file to your desktop: http://download.bleepingcomputer.com/sUBs/ComboFix.exe
- to run it dclick combofix.exe and follow the prompts to start it. When finished, it will produce a log, C:\Combofix.txt - post that log in your next reply.
A word of caution - do not touch your mouse/keyboard until the scan has completed. The scan will temporarily disable your desktop, and if interrupted may leave your desktop disabled. If this occurs reboot to restore the desktop.
==download hijackthis: http://www.majorgeeks.com/download5554.html
-copy it to a new FOLDER placed either alongside your program files or on your desktop and then... rename hijackthis.exe to imabunny.exe
-in that folder start HijackThis by dclicking the .exe; now close ALL other applications and any open windows including the explorer window containing HijackThis.
-click the Scan and Save a Logfile button. Post the log here.
..we can go from there.
