Some Notes on the Machines

This sometimes Just Plain Works:

"C:\Program Files (x86)\Webroot\WRSA.exe" –uninstall

and sometimes needs the Webroot admin password. If that password is requested but not available, safe mode activity may be the only option.

PSInfo. Does a lot of very helpful things, including repairs and much more. It is located here:

C:\Program Files (x86)\Panda Security\Panda Aether Agent\Additional files

You’ve installed it and removed it, and need to reinstall, the reinstall fails. Here are items:

• If there are files named RAVDG.TMP and/or RAVPA.TMP in %WINDIR%, the uninstall is still running. Reboot and check again.
• Make sure folder Panda Security does not exist under %ProgramData% or %ProgramFiles(x86)%.
• Delete everything in %TEMP%.
• Reinstall.

After a cleared positive from a major tool, this seems like a good suspenders-and-belt second scan:

This tool:

will remove Kaspersky products without too much of a fight.

Try this page:

One recommendable practice, is to use the tool from the above page, and then run Revo Uninstaller to complete the cleanup.

If your machine has ESET antivirus, it has a very powerful command-line antivirus scanner and cleaner. Here’s a command line I’m using:

"C:\Program Files\ESET\ESET Endpoint Antivirus\ECLS.EXE" /memory /boots /unwanted /clean-mode=delete /quarantine C:\

This one appears to work rather well:
