I never "run" anything i download. I "save" it then scan it. My system isn't hijacked niether. I recently installed windows 7 to test it out. I has been a few days and i kinda like it but I like xp a little more. I only have 512 MB of memory but it runs well. Windows website says windows 7 needs at least 1 G but i have Windows 7 running along with Avira antivirus, Iobit 360, and i can even run limewire all at the same time without major slowdowns. Thank you for your input though. I appreciate it.
