Hello giovi69 and welcome to Geeks To Go.
Personally I wouldn't trust any program to speed up the booting process no matter who it is made by especially when this can be done in the operating system itself to some degree. Although I can use this tool my-self I am not to keen on giving this information out as I don't want to say "do this and do that" and then make your system worse, I prefer to sit there my-self and do it, if any other member is confident with the tool then I would prefer them to guide you through using the tool as your system stability is my main priority.
Just to be on the safe side I reccomend you read the following topic here and then post your problem here.
Please post your problem there if it is not malware related please post back here.
Hi and thanks for your message!
So if I'm not mistaken you suggested me I should first follow the long procedure shown in the first link to make sure my Pc is not infected by any virus and then post my Hijackthis log in the second link, you kindly pointed me out on your yesterday's message, should my PC be affected by some viruses.
If instead, after using the AV TOOLS of the first link, nothing is found I should come back here at once to find out another solution rather than posting the HJT log in the second link.
Is it like that?
What if I post the HJT log now without first scanning the whole system using all the MALWARE REMOVAL TOOLS shown in the first link?
I had already scanned my PC 2 days ago with A SQUARED MALWARE, SPYWARE DOCTOR and Malwarebytes' Anti-Malware but any rogue malware was found!!
So it's likely that the slowness of my PC during REBOOT is not due to any rogue virus but probably to a problem related to the WINDOWS REGISTRY.
But anyway I'll do what you asked me to do...no problem!!
