I've never had unpredictable results.
For me, the deletion is usually harmless.
The information is reconstructed immediately
as they are running for the first time
programs.
If someone fears a risk, start
windows in safe mode command line,
, as administrator, and run the
removal with the command of MSDOS.
AVAST has its own file. Pf
Attention folder no mistake .!!!!
Is c: \ windows \ prefetch \
Delete only files.
In all cases we are talking about a PC
with severe traffic jams, slow
startup, or erratic behavior of programs
or services. Especially if it happens after Restore
the system.
It is my experience. I hope to serve you.
Although not always the problem is prefecht.

You can clean it out if you wish, it just takes a few boots to repopulate it.

Personally I have the prefetch set to 2 'prefetch only boot files,' not 1 'prefetch application launch files,' not 3 'prefetch everything' and I don't really notice any boot-time issues.
Windows 10 Home 64bit/ Acer Aspire F15/ Intel Core i5 7200U 2.5GHz, 8GB DDR4 memory, 256GB SSD, 1TB HDD/ avast! free 24.5.6116 (build 24.5.9153.762) UI 1.0.808/ Firefox, uBlock Origin, uMatrix/ MailWasher Pro/ Avast! Mobile Security

Please note: this tip does not apply to my conversation:
"Tip of the day: Do not clean out the Prefetch folder
http://www.edbott.com/weblog/2005/04/tip-of-the-day-dont-clean-out-the-prefetch-folder "

It has nothing to do with what I'm saying.
I'm not saying you have to delete prefetch regularly to get better speed or performance, which also is not true, I'm talking about a PC that has problems that may be due to prefetch corruption.

Is this prefetch corruption anything to do with Avast?

The reason for this conversation, again, is that many people
when something goes wrong he blames the antivirus.
And there is a file preftech pf each running progarma
and also boot information.
Avast has at least one file in prefech pf.
The theory I hold is that at some point prefetch
malfunctioning.
I do not speak to optimize anything, just to fix something that is wrong
at a given time. Therefore, I have spent many times that deleting files
who are in prefetch, the problem has been solved and the PC
is back to normal, no faster or optimized, but normally.
And Windows rebuilds prefetch and everything becomes as before
The final summary is that you want to try to prove it.
And no more links to articles about optimization, which is not
this matter
. If prefetch was corrupt or outdated, the deletion
removes the problem.

 And this time it has happened.
I loaded windows updates
for windows7 and everything seemed to go well
Then I saw an optional upgrade
Intel HD graphics adapter and have installed.
When restarting again everything seems to be erratic,
slow and bad. The laptop hangs half ....
I rebooted again and .... nothing.
And behold, I delete the prefetch files
and "e vualá" everything is resolved.
I hate being right.

Whenever you delete the prefetch files (pf, db) for a problem
then restart the PC.
In the next boot these files are recreated as they are running.
both boot and programs, depending on the configuration of prefetch,
In the second boot uses that information to speed up the boot
and programs.
Good luck.

For Vista and WIN 7, only delete .pf files or you run the risk of totally corrupting prefetch processing. As mentioned previously CCleaner has a prefetch option when enabled will safely deleted unused prefetch entries.

I've never had problems with corruption when deleting
prefetch files. I've never detected anything.
On the contrary, I have solved problems.
Ccleaner deletes unused files in prefetch.
But if the problem is some of those used?
For those who fear you have corruption in windows vista
and w7, you can disable the prefecht service previously.
After the deletion, activate it again.
In prefetch xp no service, but I think xp prefetch gives less problems.
And if there is more fear, you can boot the PC command line mode
and delete the files in c: \ windows \ prefetch
And as I do, as it has served me tell you.
There is no guarantee.
Just my experience on that topic.

My experience is on XP-S3 professional, VISTA-SP1 Hpremium and W7 Hpremium-SP1
and I remember that also tested on Windows Server 2003, but
this is not sure.
