Hello, I have been running 'Trend Micro PC Cillin' since I've bought my computer last year and the yearly subscription is about to expire. I was wandering if I just downloaded the free anti-virus programs that Howard suggests under his "Viruses/Spyware/Malware, preliminary removal instructions" thread, if these would be effective replacements instead of paying another $50 for the renewal subscription??? I thought I would go with an AVG Antvirus/AVG Antispyware/Comodo Firewall combination and was wandering if these would be sufficient in replacing my old PC Cillin? If so, should I try to install the others first or completely take off PC Cillin and then install the others? Thanks in advance for any insight!!
