Hello friends! I want to know what spywares and adwares are. I am having this problem now. Whenever I log in to yahoomail to check mails after opening the inbox the browser window automatically changes to what it was initially and along with that many small windows open saying that my pc is infected with spywares. If close them and hit the back button in the broser window the same thing keeps recurring. But if i click the yes in the small window and it opens a browser window which has information about all the spyware killers my yahoo mail window works undisturbed. I even downloaded some virus scan called "free spy-ware" scan and it did the scanning and found there are about 40 spywares in my system. To clean them I have to buy their products. When I checked my drives with McAfee scan which has been already installed in the system it doesn't detect any viruses. Throw some light on this.
