Option isnt there but...Symantec Anti-Virus - from the company who own Norton, but without all the resource hogging, fancy buttons and crapness of Norton Anti-Virus.
Where you get it from is upto you of course
Also, not trying to derail the thread or anything
, but looking at your sig...
New computer at Xmas:
Intel Pentium 4 3.4GHz, Nvidia GeForce 7900GT 256MB,
2GB DDR2 RAM, nForce 4 SLI Motherboard,
400GB SATA 7200RPM Hard Drive, Total Cost: $1440.00 CDN
Drop the Pentium 4, get an Intel Core 2 Duo. Far better processors, Dual Core!, sure they have lower clock speeds but they are far far more powerful, and their performance over P4's is immense. Ok Core2Duos are more expensive, but its well worth it!
Also that would mean, a new motherboard as well. Not sure if there are any SLI boards for Core 2 Duo out yet, but I'd look out for nForce5 boards for Core 2 Duo, rather than any nForce4 boards kicking about out there.
E6600 is the sweet spot for price v. performance IMO, so have a look into them! And dont be put off by them having slower clock speeds, Ghz arent everything!
