Google recently purged some 200 extensions from 
its Chrome Store inventory. Extensions and add-ons let users add 
functions and features to the Chrome Web browser, but bad extensions can
 expose users to a greater risk of spyware and malware. A major problem 
with many browser add-ons is ad injectors.
The clean-up resulted from an extensive search for embedded code that
 violates Google's policies, triggered by increasing user complaints.Google has been studying add-on security risks with a team at the University of California, Berkeley, and will release a full report of its findings on May 1.
"It is not so much the security of the Chrome browser as the security in having an open store for downloading extensions," noted Martin Zetterlund, founder of ScrapeSentry.
"I am sure Google automatically screens any extension uploaded -- but the bad guys will, of course, do their best to trick automatic screening," he told LinuxInsider.
