Symantec Norton is the best and the best engineered but the only problem is with the extra load it puts on the memory. Normal systems are just usually halted by the use of latest versions of symantec antivirus.
Not using IE (replace with Firefox). Not using Limewire (replace with Demonoid & uTorrent). Not downloading the 2kb porn.exe (replace with pornhub). That's about all I can think of, I've been virus free for 3 years.
Kaspersky; using from last 2 years and very satisfied. McAfee also good but uses more resource and less customization
I use use system mechanic on both a desktop and laptop, one license covers both machines, it is a complete suite of tools which includes a fast ram memory cleaner.
I've been using Trend Micro Pro and it has never let me down yet. Lot's of features. Quick scan, full scan, tune-up, just to name a few.
Well, I personally think ESET Nod32 and AVG are the best. There is other ones like AVAST and Norton but they just don't do as good as the other ones! Amir
I've been using Trend Micro Pro. It will do a tune up and scan. It hasn't let me down in over two years. I'm going to stick with what works.
