Microsoft Malicious Software Removal Tool

New Rogue Software Remover

Here it is. I normally don't have use for this stuff but when I do it is nice to have a current version. Eset is the Nod32 antivirus people.

Security Software Downloader (the easy way to find stuff)

SSDownloader or Security Software Downloader is a small, easy to use download manager specially designed for security software.

It is stand alone non-installing software that links to all the good security programs. Great for new installs.

Microsoft Security Sweeper

You have been directed here to download and install the beta version of Microsoft Standalone System Sweeper Beta, a recovery tool that can help you start an infected PC and perform an offline scan to help identify and remove rootkits and other advanced malware.

Here is another Microsoft virus remover. I am uncertain how it differs from "Saftey Scanner" but it is worth a shot. 

Microsoft Malware Scanner (stand alone)

Don't bother to download before needed because it does not update. How good? Don't know but it is one more option when your friend's computer is terminal.

Bitdefender has one also.

Ask Toolbar Removal

Even though Ask is dead (I think) the tool bar installs live on and removal is welcome. Here is a rundown on how to do it.

Virus Scanning Without Installing

Get ready to spreken ze Deutsch but this is an option if you are caught without a virus scanner. Stand alone functionality. On line options and/or download.
Microsoft's removal tool is already on your system, just type "mrt" in the search box.

You might want to start with (and I hate to say it) Norton

KillEmAll kill all unessential processes

Norton Power Eraser

Kaspersky Virus Removal

Kaspersky ISO Drop on Ventoy

HitmanPro
CrowdInspect
Type "mrt" in run command
Dr. Web
Ultra Virus Killer

AntiBotnet

Other possibilities

TDSS Killer
ComboFix
Remove Fake Scan Popup
Remember that removing a virus can destroy the OS ability to run so copy the important stuff off first and be ready to do a fresh format and install. Actually the data can likely be copied later but your choice. I would like a fresh system if my machine had been compromised.

This "rename" trick is one I have not used and will certainly try the next time someone brings an infected computer to my couch for me to "fix". The other hints on the above link are good also.
