Delete Fake “Microsoft Office Activation Wizard” Warning Virus

Fake Microsoft Office Activation Wizard is a tech support scam designed to extort money from Windows users. The malware locks your computer and asks for Microsoft Office software activation. It pretends to be a legitimate warning and looks like a component of the operating system. In reality it is just a malware limiting the access to your computer. Sometimes it appears even if you do not have Microsoft Office installed on your computer at all.

The scammers provide a fake Toll-Free phone support line. You are required to call the line in order to receive an activation code. The criminals will ask for a payment before providing the code. The line might charge high rates for calling as well since it is not a legitimate Windows support center. You should never follow the instructions provided by the scammers. Instead, read below on how to remove this fake “Microsoft Office Activation Wizard”.

The required product key has already been discovered by virus researchers and it is possible to remove this fake warning quite easily. However, after unlocking you should remove the malware from your computer completely. Therefore, we have an automatic tool which will scan your PC and remove the threats. It will also protect it in the future. We also have a manual removal guide if you feel comfortable editing important Windows system files and settings.

What is Microsoft Office Home and Student Activation Wizard scam?

This fake warning targets unsuspecting Windows users and tries to persuade them that their Microsoft Office license needs activation. A limited number of days is given before “the product becomes unlicensed”. In reality the warning is unrelated to legitimate Microsoft Office software. The popup will still appear if you have an activated copy of the software installed or even if you do not have Microsoft Office at all.

The design is made to resemble legitimate Windows warning so even an experienced user might find it hard to distinguish between this and a real system popup. It even includes Help and Privacy Statement buttons and an option to activate the product over the internet (although not working and forcing you to call the support line). The only giveaway is that it usually limits other computer functionality as well by staying on top of other applications: a legitimate Microsoft Office error would only limit access to this software only. Also, you can spot spelling and grammar mistakes (e.g. misspelled word “becames”) although in general it is more professionally made than many other fake lockers.

Here is an example of a warning screen text:

Microsoft Office Home and Student 2016

authenticate this copy of Microsoft Office. This wizard will guide you through the
