Microsoft, Lenovo and other software makers have been working 
overtime in an effort to eradicate the Superfish adware.
The good news is that since the Redmond-based company first got involved, the number of Lenovo machines detecting the vulnerable version of Superfish have dropped dramatically.
As per recent reports, Microsoft’s malware detection data says Superfish has been successfully removed from 250,000 Windows PCs. On 21 February, as per Microsoft’s observation, number of infected PCs were 60,000, whereas now the number has been reduced to 3,000.
Microsoft has assisted extensively in cleaning up Lenovo PCs and the process underwent from 20 February to 4 March. The Malicious Software Removal Tool (MSRT) has been used for the cleaning process. This tool includes a set of fingerprints which can detect as well as delete malware.
Along with Microsoft, Lenovo and McAfee also released tools to clean up Superfish. Lenovo also published a step-by-step guide for common users to help fix the adware manually. The Superfish adware could install a fake root certificate into the Windows certificate store which seems to be real. The browser starts trusting the fake certificates and hackers find it easy to crack it.
