Came home from work to a phone call from a "Kevin Davis" who said that my computer was full of viruses and would crash in a couple of weeks if his company were not able to fix it for me. He declined to write to me with details of the problems but did give phone number and name of company - in Brent....
"windows security service centre"....AIBU to think that it would be foolish of me to just give his company access to my computer to "fix" it? He also said he had my computer license number????
