Microsoft reveals that the number of infected PCs were around 60,000 on February 21, and have now reduced to around 3,000. The company has reportedly helped clean up a quarter of a million Lenovo PCs from February 20 to March 4 using its Malicious Software Removal Tool (MSRT) that includes a set of ‘fingerprints’ to detect and delete malware. Along with Microsoft, Lenovo and McAfee had also released their tools to cleanse Superfish. Lenovo has also  published its step-by-step guide for users to manually fix the adware. The Superfish adware is capable of installing a fake root certificate into the Windows certificate store that appears to be genuine.  The browser will trust all the fake certificates generated by Superfish, paving way for hackers to easily crack into it.
