Not sure if there is malware

Your basically clean except for a few stray entries in the registry that Panda is not giving any useful inforamtion on. I suggest running Ewido as in the below link and attaching the Ewido log.

Running Ewido Anti-Malware


Then run HijackThis and fix the below minor items:

R1 - HKLM\Software\Microsoft\Internet Explorer\Main,Search Bar = about:blank
R0 - HKLM\Software\Microsoft\Internet Explorer\Main,Start Page = http://go.microsoft.com/fwlink/?LinkId=56626&homepage=prosearching.com
R0 - HKLM\Software\Microsoft\Internet Explorer\Search,SearchAssistant = about:blank


Now we need to Reset Web Settings:

1. If you have an Internet Explorer icon on your Desktop, goto step 2. If not, skip to step 3.
2. Now right click on your desktop Internet Explorer icon and select Properties. Then click the Programs tab and then click "Reset Web Settings". Now go back to the General tab and set your home page address to something useful like www.majorgeeks.com. Click Apply. Click Delete Cookies, Click Delete Files and select Delete all Offline content too, Click OK. When it finishes Click OK. Then skip step 3.
3. If you do not have an Internet Explorer icon on your Desktop, click Start, Control Panel (for some systems it may be Start, Settings, Control Panel), Internet Options, Programs tab and then click "Reset Web Settings". Now go back to the General tab and set your home page address to something useful like www.majorgeeks.com. Click Apply. Click Delete Cookies, Click Delete Files and select Delete all Offline content too, Click OK. When it finishes Click OK.

How is everything working? If you run Avast again, is it still finding any problems (ignoring Panda stuff which is false).

 

Looks good!
