I changed my antivirus from McAfee to AVG about 2 weeks ago. Yesterday I started getting constant pop ups alerting me of spyware installed on my computer and to activate Antivirus System Pro.
I upgraded from AVG Free Trial version to payverions and scannned my computer but nothing was found.
Even after disconnecting my desktop from the internet I still get the popups alerting me of spyware infections. A browser keeps opening with a subscription screen to purchase Antivirus System Pro.
Upon googling Antivirus System Pro I found several links on how to remove this spyware from my computer. However, I'm not sure who to trust.
Does anyone know a trustyworthy method of removing this spyware?
Also, how complete is this removal process? Part of me just wants to reformat my computer if that is the best and safest choice.
