Now, almost all AVs program are memory suckers! Among Norton, McAfee and other AVs, Pc-cillin is least sucker! So, think twice before you upgrade your AV or try something else instead of purchasing a update if you are running a old pc like me.
I guess, all AVs developers are running new PCs like Intel P4 3Gz on Windows XP, and expecting everyone to upgrade your pc sooner or later.
In general, pc-cillin is easy-to-use in interface, with free phone support. McAfee has only internet support while norton charges for phone support.
I was using McAfee since 2000, and never satisfied with their product. I was forced to switch to Pc-cillin when I purchased McAfee 2005 upgrade because it sucked all my RAMs. Also, because of my out-of-dated McAfee firewall, hacker penetrated my McAfee 2005 upgrade and stole my password, blocked me from receiving any further update from McAfee server. McAfee has the worst update mechanism, and I must set internet explorer to accept ActiveX and cookies(which let the hacker to control my machine easily),then login first to their McAfee server in order to receive upgrade. So, the hacker got my McAfee password, free update right for a year, and I was left unprotected at all. No wonder, I heard lots of people can get free McAfee AV updates year after year even though they need to login first to McAfee server.
Pc-cillin do updates like Norton simple and direct!!!
The only thing I would like pc-cillin to add on is something like McAfee Visual Trace so that I can easily identify the intruders instead of a IP address.
Antispy is also weak, neither do Norton, McAfee and other AVs.
It is so far an excellent AV product in the market.
