I've been infected before, but THIS one is a doozy. Help?

Antivirus Soft showed up on my laptop, so I came here to run through all the possible ways to fix.

I can not open or use anything unless in safe mode. I can't access the internet.

I did all the pre-cleaning steps (except couldn't remove Search Assist, because I am forced to be in Safe Mode, and couldn't remove Java update 17).
I tried to run Superantispyware, but it says "The system administrator has set policies to prevent this installation" (I'm the administrator, and didn't set policies.

I tried running malwarebytes anti-malware, it shows 0 infections.

Would a Hijackthis log help?

 

Thanks, anyway, I found a fix.

 

In my case, it was quite simple.

Ran Hijackthis, and fixed 2 entries:

O4 - HKLM\..\Run: [wbjteggo] C:\Documents and Settings\Claire\Local Settings\Application Data\yxtgnr\ihlesftav.exe
O4 - HKCU\..\Run: [wbjteggo] C:\Documents and Settings\Claire\Local Settings\Application Data\yxtgnr\ihlesftav.exe

Then made sure to check 'see hidden files' was checked under folder options, rebooted, then manually removed C:\Documents and Settings\Claire\Local Settings\Application Data\yxtgnr


All is swell so far (knocks particle board).
