Hello ford66 and welcome to RSF,

I'm not sure how much we can accomplish if you are unable to install programs or get HijackThis to run a scan.

This batch file will start HJT from the runonce key, so that is starts before lots of malware, let's see if we can get a scan.

Copy the bolded below into a new notepad document (not wordpad).
Click file> save as...> call it Hijackthis.bat > file types *all files*> and save it to desktop.

@echo off
cd\
echo REGEDIT4>Temp.reg
echo.>>Temp.reg
echo [HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\Curr entVersion\RunOnceEx]>>Temp.reg
echo "Flags"=dword:00000008>>Temp.reg
echo [HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\Curr entVersion\RunOnceEx\000]>>Temp.reg
echo "runonce"="\"\\!HJT.bat\"">>Temp.reg
echo.@echo off>!HJT.BAT
Echo.echo Hijackthis will open before the windows desktop>>!HJT.BAT
echo.echo Scan and Fix only what your forum adviser suggested>>!HJT.BAT
echo pause>>!HJT.BAT
echo.start hijackthis.exe>>!HJT.BAT
echo.echo ONLY when finished with hijackthis close it and,..>>!HJT.BAT
echo pause>>!HJT.BAT
echo.del Temp.reg>>!HJT.BAT
echo.CLS>>!HJT.BAT
echo.exit>>!HJT.BAT
regedit.exe /s Temp.reg
echo Please restart your PC now
Echo Just before the desktop loads Hijackthis will open,
echo Scan and Fix only what your forum adviser suggested
pause
CLS
exit

Run Hijackthis.bat then restart your PC.
Hijackthis will open before the desktop loads. Run a scan with HijackThis and save the log to post here.

Also, please do provide the results of the Avast log, it may prove useful.
