Hosted Ip Telephony

so I am getting Internet Explorer 8 to run faster. I have my computer running very good, but IE is a pain. I have an HP dv6000. is a little 32. Windows Vista. I was about 35% free space on my hard drive, so I went to buy an external drive, 500 GB hard drive and put my music and photos and other crap out there. and I defraged. ran disk cleanup, conducted an audit of the registry, scanned for questions on the C drive, I am now about 62% free space. I hoped everything would help to IE, but it did not. I have no antivirus software so I know if I have one or not, but sometimes play random music in the background even when not all open programs. so I think I may have a virus? so now I'm looking on the programs running in the background, I read about using elses question ... http://www.sysinfo.org/startuplist.php?f this site to spend for programs running, but I'm still confused, so I'm looking for someone who can actually tell me
- Yes, keep it "
- No, it's a virus or something useless "
"Maybe - depends on whether or not you want"
? - I do not know "
