Avast very, very slow at startup!!

OK, the final thing to check, HDD

www.hdtune.com

see whether your HDD drive status is OK...

Compare Current and Worst Values
normally, the values should be the same or have only slight differences such as 1~10

and you can also scan your HDD speed (Benchmark)
the average read speed should be

~30 MBps for 5400rpm drive
~60 MBps for 7200rpm drive

If your drive show any abnormal behaviour, there's no point formatting and reinstalling Windows

Well, no the HD either.
All healthy and average speed is 31,0 MB/sec - it`s a 5400 rpm.
Thanks anyway, seems like a ghost problem...

Well I think your only way out is install a fresh Windows

of course, after installing Windows, you can immediately disable the unwanted services and startup to boost perfomance

I suggest you run Windows with the 'default' list of services for some (or long) time.
If the user changes the settings and he/she is not an advanced user, more trouble he/she will have... messing...

VERY GOOD NEWS!!!
Finally I did figure out what was messing up my startup!!!
Not Avast, not services, not HD, not programs at startup!!
Turns out that the Intel internal wireless connection card enabled was the culprit!
Disabling it did the trick. Now after hitting On button, everything`s fully operational in 40 secs!! Just a question of enabling it afterwards when that`s the case....
I do thank all of you who tried to help, I did learn quite a bit here!!!
