well, what if a trojan horse / keylogger is passively reporting ur passwords to the big bad h4x0r ??
also, all those security software will hog a lotta sys. resources, may occasionally conflict wid each other (xcept anti-spy). better to hav a single solution which does the job...imho
the question is why would you download that keylogger or trojan horse :cool2: , with a tight setup :no: , your antivirus or antispyware would surely alert you to its presence
. not all trojans try to establish a direct connxn via a port for your firewall to step in(thats why i told its best to have multi-tier protection, i think the worst kind of offenders always hog your browsers cache)
i disagree on single protection, most keyloggers, trojan horse would be piggy banking on some other application, so without a anti-virus and anti-spyware you will be fooled into allowing access, so all applications do there own job, its better to have specialists than a all in wonder
as for system resources, i always have antivirus & firewall enabled, every few days scan my system for spyware, this is a neccesary evil, better safe than sorry.
about download speed, if its coded right they are supposed to do it unobtrusively with a minimum impact on your speed.
vivek, good programs never ask you to disable your firewall, its like asking for a persons locker key
some applications just have to be setup properly like torrents, i use bitcomet with nvidia firewall & its fine.
ok one more thing, try to check how good your firewall is, try this, it was posted before on techenclave.
