Is having real-time virus protection bound to slow down boot time?

[Amaggard]

Whenever I start up my computer, it takes 5 seconds to boot, but then once I log on, the post boot process takes extraordinarily longer. I disabled almost every startup process, using autoruns and msconfig, and analyzed a few boot ups in windows performance analyzer, and narrowed it down to 1 program; my real time antivirus. The antivirus software I used to use, was AVG, and recently it caused the post boot process to take up to 3 minutes sometimes! My computer would start up quickly, then once I logged on I would just stare at my desktop for minutes until everything would suddenly load, since AVG was slowing down the process. I looked at the event logger, which shows processes and errors, and I went to diagnostic-performance and it showed that AVG was the root of this problem. I uninstalled AVG and rebooted and it took less than a minute for the post boot process to complete. I now use Ad-Aware real time protection, which is much faster, but event logger shows that even Ad-Aware slows my post boot process down, by 30 seconds to a minute.

So I ask, is having real-time virus protection bound to slow down a computer's boot time? Will every real time protection software slow down boot time? Is it just in the nature of having real time protection? I would really like to know.

yes...anti-virus takes time to load...however, how long it will take, depends on how heavy or how light it is...
this article might help u in understanding the durations...

if you know the service it starts, you could set it to delayed start instead of automatic which will let it start up a bit after boot up. windows tends to stagger these delayed starts to make it less of a hit.

win defender in win 10 does this to me and would get my hdd at 100% for a good 5 minutes at each boot up. got old real quick so i disabled that. now i get to my desktop and can do something within 30 seconds or so after booting.
