In Ccleaner>tools>uninstall,i have noticed these three entries:
A10 minimal
Ai0 software
Ai0-scan.
Could anyone tell me what these entries are for?

p.s i am running the latest version of ccleaner.

http://www.sysinfo.org/startuplist.php

try that

All-in-One software, usually for printer/scanner/fax devices (usually HP).

Also, are you sure "A10" isn't really "AIO"?

Also Dell branded Printer/Scanners made by Lexmark may have that.
And Lexmark branded Printer/Scanners.

Edit:
That's the only problem I really see with CCleaner's Uninstall list in that it will list some individually installed components that are actually the parts of a whole parent application.

Thankyou for the info
D.jlizard,you are correct,it is AIO not A10 I do apologise! As for it being possibly related to Lexmark printers/ scanners etc,I have never had Lexmark installed on this particular computer so I wonder where these are from.

so is that PuP or is it useful?

PuP = potentially unwanted program ( for those who didn't know )

for all the nublets

Could possibly be a pup but that's unknown until a HijackThis log is posted. I've personally only seen AIO listed if there's an All-In-One printer/scanner installed on a system, but who's to say it couldn't be malware related, however I won't speculate.

Do you think that it's worthwhile posting an hjt just in case?

don't bother. when i had AiO(and the other useless programs) installed, i used HijackThis and it found nothing.
