So here's the deal. I was an idiot and clicked on a file to download from an unknown host and let it extract. I didn't do anything so I restarted the computer and after that could not boot into windows at all. I would be able to get to the user log in screen but once I click on the user it say's loading personal settings then automatically goes to saving settings and turns off. Same thing went for safe mode. I tried check dsk and it did not work. I used a bootable avg to scan and it didn't find anything. I ended up doing a recovery from XP sp 3 disk. After doing this I was able to actually log in with safe mode and get access to all my files. In regular mode it lets me choose the user but after that it brings up my background I had set and no icons or anything, just my mouse pointer which I can move around but nothing else.I can hit Windows+ U and it will bring up that voice thing but nothing else will work. I have also run malware bytes in safe mode along with microsoft malicious software removal tool. I cannot run Hijack this because it say's "The system administrator has set policies to prevent this installation".
I just want my machine back without going the route of reformatting. Is there anybody that can help me with this or give me assistance on what I can do???
Please help this is driving me insane.
