Rollover is deemed as a nasty adware that should be removed quickly:
Rollover is an ad-supported program that was created by the cyber crooks with the purpose of profit. Once your PC is attacked by Rollover, your web browser like Internet Explorer, Google Chrome, Mozilla Firefox or other type of internet browsers will be attached with harmful codes and add-on. After that, whenever you surf the web, you will be harassed with tons of pop-ups created by Rollover and be redirected to some advertising websites or phishing domains against will.
In some circumstances, ads by Rollover are about fake software update, if you download and install the rogue programs, your computer may have a great risk being infected with other PC threats, such as Trojan horse, worms and spyware.
