I downloaded a application which was absolutely useless but with that software another program was downloaded due to which the following happens :
Whenever I open a browser (IE or Firefox) an unwanted website named "www.mystartsearch.com" loads and the biggest problem is I can't disable it.
Some programs are always started and I can't stop them or uninstall them no matter what I try (like HpIU.exe, loader32 and iePluginService). I have tried both the methods (manual methods and by using software like SpyHunter) so, for me both the methods were ineffective. For now I am totally helpless.
I tried some random things like deleting the entire SupTab folder in Program files from C drive. I have tried closing HpIU.exe and loader32 from task manager (I can't even close these programs).
Please help me to get rid of this malicious program. My OS is Windows 7 Ultimate. My antivirus is Quick Heal Guardian (ineffective in this case). The software I downloaded was from the website 4shared (I entered the site with the help of a Youtube video and below this video was the link I used. According to my information this is a malicious program that helps other bad programs to enter the computer and the one behind the scene is very frequently updating this and this might be the reason why I was unable to disable it. I doubt that the information provided on other forums was old. I want a method which is effective and free of cost.
