I got this Sweetpacks malware apparently while downloading another program and ultimately it changed my browsers homesite to SweetIM site and the default search to SweetIM search. Avast was able to remove the browser add-on but it kept coming back. Avast Pro Antivirus didn't recognize stijj.exe, that apparently caused the problem, on my computer in a scan even though PUP was set on. I was finally able to remove the malware with AdwCleaner. I find it weird that my avast didn't find it or remove it since when I googled stijj.exe and sweetIM I found out that a lot of people were suffering from this malware.
