I ran the MalwareBytes Free version 2 today on one of our laptops. I do this every week or so. The laptop had 43 files related to the Cartwheelshopping PUP. In the past, I've just quarantined the PUP's & malware found and not thought a thing about it. However, I recently did that with my sister's laptop and completely hosed the computer. She had a large number of PUPs which I quarantined. After that she had errors on boot up, lost function in some of her applications, and was generally real unhappy. I was able to eventually to restore functionality, but am now really leery of just quarantining malware. I can see on some other sites that they think the removal of CartwheelShopping A is a lenthy process with many steps including uninstalling the program, resetting browsers, running multiple scans with multiple applications. Much of it sounds like applications I see you advising people to use. My question is - is it safe, generally, to quarantine PUPs or other malware or should I stop using Malwarebyes to remove scanned items and go to using the more multi-step processess after Malwarebytes finds the problems? Thanks for the help with this.
