You may have noticed Microsoft's Malicious Software Removal Tool in your list of available Windows Updates. Heck, you may even have seen it in your Add/Remove Programs and wondered where it came from. The MSRT can actually be quite useful, and it's a fast, simple way to remove a number of common malware infections.
In an update pushed yesterday, Microsoft added Cycobot to the list of malware that MSRT can remove. It's a nasty little backdoor Trojan, and one I've seen on plenty of the systems I spend my days repairing. The full list of malware (more than 120 types) which the tool can remove is available on this page.
MSRT is a good little tool to add to your security arsenal, but a multi-app attack is always best. Make sure you've got a good antivirus program installed, and keep Malwarebytes handy just in case.
