Spam call
I got a call today from 020723083xx purporting to be Virgin Media.
The told me they were getting error message from my P.C. and it was slowing down my internet.
In order to check if they were genuine I asked him my IP address.
His first three digits were incorrect. (go figure..)
I asked him how they got the messages despite me being behind a router and a software firewall.
Funny thing he hung up....
Beware these scammers.
I got these saying my B.T. broadband was doing the same and played along (not having BT broadband)
They ask you to open event viewer and look at all the errors with there... (This is normal as Windows isn't perfect - but most can be resolved by looking up the error on technet and keeping windows up to date).
They will then ask you to connect to a certain website and they will take over your P.C. and demand a ransom.
They will then have your account details and clear you out...
I fear some people will fall for this.
