A Portable Antivirus Software from Microsoft

Is your computer infected with a virus that is preventing you from downloading security updates from the Internet or from running any antivirus program on that machine? Or are your looking for an antivirus software that can be carried on a USB drive to quickly scan any disconnected computer(s) for viruses or malware?

You should check out Microsoft Safety Scanner. This is a free antivirus software, always updated with the latest definitions, and requires no installation - all you need to do is copy the program executable msert.exe to an infected computer and double-click that file. If it detects a problem, the infected files will be quarantined.

You may either do a thorough scan - check every file and folder - or a quick scan that checks a limited number of folders that are most likely to contain viruses, malware or spyware.

Microsoft Safety Scanner is available as a free download for both 32-bit and 64-bit version of Windows. You may use on Windows XP, Vista or Windows 7 machines and, unlike Microsoft’s other antivirus software, Safety Scanner doesn’t perform a check for genuine Windows.

The program expires after 10 days but you can always re-download it with the updated virus definitions. It won’t however scan your Outlook emails or your network drives for any possible infections.

Silently and remotely remove Symantec Antivirus

There is even a line there showing what program it calls to actually uninstall which is (surprise, surprise) MsiExec.exe. Just typing that line in a console starts the removal process just as if you called it from add and remove programs.
The actual line needed with all of the proper arguments is.
"MsiExec.exe /norestart /q/x{BA4B71D1-898E-4306-AE87-8BA7A596F0ED} REMOVE=ALL"Typing msiexec /? will give you a dialog box with what all the arguments
corporate edition of Symantec's antivirus can require a password to be uninstalled.
to fix the password issue, we can start up regedit and from the file menu connect via the network to the remote machines registry. Then navigate to the following key.
 "[HKEY_LOCAL_MACHINE\SOFTWARE\INTEL\LANDesk\ VirusProtect6\CurrentVersion\AdministratorOnly\Security]"
In that key make sure the two following values "LockUnloadServices" and "UseVPUninstallPassword" are zero. That takes care of the password asking problem.
Lo and behold the remote computer dutifully uninstalls that pesky virus program ready for a fresh install.

The account that you do all this work under has to have domain administrator privileges and the remote computer has to be joined to said domain.
