My AVG Ani-spyware license is about to expire. AVG has proposed my an attractive offer to upgrade to AVG anti-malware. I am tempted to accept it. But I already have a (good) virus scanner on my computer(s). So here is my question: Can I install AVG on a computer which has already an other virus real time scanner and use it (AVG anti-virus part of AVG anti-malware)) as an on demand scanner BUT still use the AVG real time spyware scanner (the other part of the anti-malware scanner) ? Thank you in advance!
