I have been using both NOD32 2.5 Beta and Dr. Web (not at the same time) to determine which one I will purchase. I like them both...they both seem to be fairly easy on system resources and both seem to be well regarded here at Wilders. Is there any strong reason to go with one over the other? Price is insignificant as both are under $50. (I have set $50 as my limit for this particular purcase) I haven't been able to get Dr. Web's spiderguard and spider mail modules to show themselves on my window task bar...and I have checked the appropriate boxes and rebooted a few times. Perhaps the load on startup features are disabled in the demo version? Other than that...the program seems to run fine. The NOD32 Beta has been a pleasure to use as well. No problems so far and it seems to be a favorite of many here at Wilders. The other choice I had considered was BitDefender. I have been hesitant with BD after reading something about an "injection" type process it does that apparently can slow some systems down. I have no clue what that means...perhaps someone can fill me in and let me know if it deserves as much consideration as Dr. Web and NOD32. I do a fair amount of online gaming (World of Warcraft), but other than that, just fairly basic web surfing and such. I am currently running the following: XP Home with SP2 1.8 Ghz AMD 512 Ram BoClean 4.12 (licensed) Ad-Aware SE Plus (licensed) Sygate Personal Firewall (free version) Ewido Security Suite (free version for on demand scanning) Pest Patrol (licensed...but I don't use it anymore since getting Ad-Aware) RegProtect (free version) Thanks much for your help.
