I have been windows 7 version on lenovo machine with out any issues since last two years. two days back I downloaded one update for printer and restarted my machine. All is ok except there is infection of an adware called pricechope and what ever i type or search it keeps on poping up referal sites and its annoying . I reintslled Chrome but no use. Please let me know what best can be done to avoid this and remove it. I used CCleaner and later tried Mbam but did not load so tried to re-install it but while installation i keep on getting runtime error as below ---- and Mbam can not be installed successfully.
