Files "ads" sospetti segnalti da Hijackthis

[barocco]

Premetto di non riscontrare alcun problema nel mio pc.
Cercando nelle varie funzioni di Hijackthis ho eseguito una scansione relativa agli "ads", dapprima togliendo la spunta nella voce "Quick scan (windows base folder only)" poi togliendola anche dalla voce "ignore safe system info streams".Ho inserito il log nel sito di hijackthis dove vengono indicati due files come "forse sospetto":

C:\Users\All Users\TEMP : 5C321E34 (125 bytes);C:\Users\All Users\TEMP : 5C321E34 (125 bytes)

.
Potete spiegarmi cosa sono precisamente i files "ads" è qual è la loro funzione? ho cercato di documentarmi in merito ma non sono riuscito chiarirmi di cosa effettivamente si tratti.

Ho seguito il percorso dei files suddetti ma la cartella risulta vuota, perché? Prima di fare cio', ho deselezionato "non visualizzare cartelle nascoste".

Coa comporta l'eventuale eliminazione di questi files?

Allego il log, per un vostro parere su eventuali pulizie da fare. Grazie

Lasciali tranquillamente lì dove sono.

In un altro forum mi è stato scritto che l'aver disabilitato la voce "ignore safe system info streams" comporta seri rischi?
perché e di cosa si tratta?
Grazie.
