False Positives

Hi Forum members,

I am new to this (all) Forums, hopefully this question is in the right place, although there might be several questions contained in it.

Can anyone help me.

I have recently been on holiday so my computer was not in use for a month. When I returned several of my programs required updates (System Mechanic, Norton, Chrome). Since doing these updates my Chrome Browser has been very slow at loading pages and I have been receiving a large number of security warnings from Norton of bit4d, bita9.tmp files/ Suspicious Cloud threats. Looking at the file name of these file they looks suspicious (are very long, see attached pdf)  but as they included the words chrome_updater I am wondering if these are what is causing the pages to be so slow at loading, Is my Chome infected. Or is it because these files have been quarantined that it is not working correctly?

I have looked up the "False positive" section on the forum and started filling in the reporting page till I got to the section where it asked for me to upload the source file (?) what source file? (Chrome? or the infected file) . I cannot find the infected file in Quarantine (Cannot even find the "Quarantine" files on my computer.)

Should I use the Norton Power eraser to see if it clears the problem My browser is not being hijack to any unnamed sites it is just very slow at loading or I get the Goggle message that it failed to load ("Kill page")

 

Any suggestions
