pc running soooo slow

hi
my sisters laptop which im currently using is running soooo slow, is there a method i can follow to help me find any nastys on there or just a general clean up

first check for malware with this

Malwarebytes Anti-Malware 1.51. http://filehippo.com/download_malwarebytes_anti_malware/
make sure the program is updated before you scan
click on the remove selected button to quarantine anything found

post the scan log here

here is the log from mbam

ok nothing found so suggest you post an OTS log and let Essexboy have a look

Follow this guide from our expert malware remover Essexboy

( post the logs here in this topic and not in the guide )

To avoid using multiple post with copy and paste you have to attach the log`s
Lower left corner: Additional Options > Attach ( OTS log ) save OTS log as ANSI

Essexboy will look at the logs when posted…

pls stay with your orginally posted thread as this will create confusion among essexboy and other people on the forum…
