I do not notice a malware called Great Find in the system until the computer begins to slow down. Internet Explorer, Chrome and Safari get rather small ads on the right top corner. Key words are underlined at times. My friend helped me with steps in Chrome Help Forum and this article. But Safari is still performaning weirdly. kaspersky scans a file and delete it already. Any good idea? Thanks in advance!
