Caller: Scammer, pretending to be my internet provider

Gave me a name - Dave and then identified himself as my internet provider. Noticing that we had a few drop outs lately, he wanted to test our internet speed. Asked me to go to ultraviewer.med.net which I was googling in the background and found out it was a remote access program. I mentioned this to him and he said he wasn't going to take access of my computer. I told him I wasn't comfortable with this and he should call back later when my husband was home. I phoned my internet provider who confirmed this was a scam. They don't do remote connection and they don't call on mobile numbers. Be careful
