I keep getting a virus warning on my Android phon internet Chrome and regular Google. It tells me to logon on to Samphico.Top or togying.pw to clean the virus. The anti-virus/malware protection I have installed shows no problems. I keep clearing the cache and browser history but the warning sites keep appearing. How do I stop this? I use my Android while I'm at work and it's extremely annoying to have to keep clearing everything and to have it keep appearing.
