IE icon changing colour (light>dark blue) and quality, concerned???

Hi I don't know how,why,where but my IE icon changed recently of its own accord. I changed it back via properties but later it changed again (light>dark blue) and of lower image quality. Strangely this icon color is not avail in the standard change icon options. After this occurred twice I have changed it to IE icon on sheet of paper and this seems to have stopped this.

I have conducted antivirus scans with AVG, then disabled and installed NOD32, no viruses (apparently)

Spyware/Adware: spybot, adaware, Windows defender, nothing

Start up monitor: WinPatrol, nothing new

Recent installs: Window defender, ATI catalyst suite v6.2, SIS UVGA v3.72

Has anyone had this happen and should I be concerned???

 

Completed all scans; IE icon was changing colour (light>dark blue) and quality

My IE icon changed recently of its own accord. I changed it back via properties but later it changed again (light>dark blue) and of lower image quality. Strangely this icon color is not avail in the standard change icon options. After this occurred twice I have changed it to IE icon on sheet of paper and this seems to have stopped this.

Bitdefender: 0 threats reported and strangely could not find option to view and save report after >1hr sanning did not want to repeat process, don't mean to be slack).
HijackThis: attached

Summary:

Both NOD32 and Panda found the K-Lite\traffic.core, this was supposed to be a barebones version of K-Lite (no spy/adware) given to me by a friend. If I remove this component will it effect the application as a whole?!?

P.s. conducted on PC1 below
