Some years back, I did a rather exhaustive test to anti-virus software for small to medium business with support for MS Exchange (cleaning and filtering purposes).
After some steps and iteractions with vaious products/vendors, TrendMicro and Symantec reached the point of my choosing.
My decision was meant to TrendMicro because at the time, although my satisfaction with Symantec solution, their product was slower. When I say slower, I mean in terms of client boot up. At that time TrendMicro seemed (ans was) more light booting up and in operation.
Some years passed (5/6) and now it seems to me that year after year, update after update TrendMicro is loosing the speed battle to Symantec.
Right now, TM processes are stalling heavily the boot process all the clients.
Can anyone share their experience regarding this problem? Either if you do not use any of these products, please feel free to leave some feedback.
Thank you all.
Software/Hardware used: TrendMicro WFBSA, Symantec End-Point Security, Windows Servers, Clientes and MS Exchange
