Infected with Rootkit.Win32.Zbot.sapu? – How to Remove It?

Is your computer infected with Rootkit.Win32.Zbot.sapu? Does your computer perform weirdly due to this threat? Do your installed antivirus programs fail to remove it and it keeps coming back over and over again? Take it easy. Follow the guide in this post and you will successfully get rid of the infection from PC.

Description of Rootkit.Win32.Zbot.sapu

Rootkit.Win32.Zbot.sapu is a variation of the banking Trojan ZeuS that is generated to install a rootkit. Usually, it spreads over the networks via the bogus Starbucks ‘Gift from a Friend’ email messages. The bogus Starbucks email messages contain the infected files attached which declare that a friend has sent computer users a gift. If your PC gets the malicious email, you will find the Starbucks email messages are entitled ‘Starbucks Coffee Company gift from your friend’ and the following messages may be found in the email:

“Your friend just made an order at Starbucks Coffee Company a few hours ago. He pointed he is planning to make a special gift for you and he have a special occasion for that. We’ve arranged an awesome menu for that case that can really surprise you with our new flavors.

In the attachment you can view the whole menu and the address and the exact time you can come and celebrate this day with your friend. He asked to stay anonymous in order to make some mystery and desire to come and enjoy this atmosphere. Have an awesome evening!”

As a matter of fact, Starbucks permits customers to gift friends on various occasions. However, these bogus email messages have nothing to do with the coffee company. This can be specified by the way it is written that it is not an authentic email message of Starbucks. If you are careful enough, you will notice the sender’s email address. The vicious emails are sent out from Yahoo and Gmail accounts with ‘high importance.’ The file that is attached to the unsolicited email messages is not a menu, but a malicious executable file, detected as Rootkit.Win32.Zbot.sapu. If you are taken in and click on the attachment, the infected files can be downloaded and installed on your computer.
