I cannot currently access IE after experiencing a flood of pop ups from "Win 7 Anti Virus 2011" which warn of ever more serious attempts to hack into my system and give dire warnings of credit card theft, corruption of files, theft of personal data etc, etc. It initiated an unprompted scan of my files and claims to have found 26 corrupted files and strongly advises me to register and purchase $60 worth of anti virus protection.
I ran a full scan on McAfee (pre-installed on my Dell laptop). This revealed no threats or issues and said my computer was secure, protection was active and no further action was required.
So, a) assuming these pop ups are a devise to frighten me into buying anti virus software I don't need, how do I get rid of them and regain access to IE, b) once back online, would I be better advised switching to a different web browser such as Google Chrome, Mozilla or Firefox?
