Sometimes, official site of a certain app is hacked, and the download is laced with malware. (This usually happens when the site is not HTTPS.) So always check before install...
Download and install subinacl.msi from this site:
Then copy and paste the following into notepad and save as acl.bat :
Run the batch file as admin and the accounts should be reset to their defaults.@echo off
title Resetting ACLs...
cd /d "%ProgramFiles(x86)%\Windows Resource Kits\Tools"
echo Resetting ACLs...
echo (this may take several minutes to complete)
echo System Drive...
subinacl /subdirectories %SystemDrive% /grant=administrators=f /grant=system=f
echo Windows Directory...
subinacl /subdirectories %windir%\*.* /grant=administrators=f /grant=system=f
echo Press any key to exit . . .

1 VT is "the place" where you can check any file that exists, and see if one or more of 54 participating antivirus engines considers it malicious. If only 1 or 2 flags it as bad, then it is probably a FP (false positive), or maybe it is a very, very fresh malware sample. But usually, such a low score means it is clean.
2 Downloading apps from websites: that is my personal paranoia. Sometimes, the FTP of a known and trusted site gets hacked, and criminals replace the regular download with a malicious one that looks and smells the same as the genuine one.
So even if you download from a site that you know and trust, it is still a good idea to check out the file on VT before running it.
