I’m currently experiencing a really bad virus.

First, I got a Windows Antivirus Pro, but managed to remove it and run Malwarebyte’s Anti Malware. After that, I thought it was all good, but my search results on google started redirecting to other things. Then, I got a Windows Police Pro. I removed the program files and fixed the registry so I could run programs. But there’s still something on my computer. Whenever i try to run an anti spyware or anti malware program, it halts abruptly and then I can’t open it at all. Also, my registry cleaner had the same problem. They all failed when they got to a cirtain part of the registry. AVG got through the registry without failing. I also have some suspicious processes:

msiexec.exe
mscorsvw.exe
b.exe

Also, when I was playing a game, I noticed a whole bunch of clicking sounds, as if the web browser went to another page. There was no web browser running at the time though.

Can anyone help?
Some more details:

I’ve tried SuperAntiSpyware and it won’t work. It always stops and crashes, even in safe mode.

For some reason, All my system restore points are gone.

I use:
Ad Adware SE Personal
avast!
Spybot Search and Destroy
SUPERAntiSpyware
Spyware Blaster

And to clean my registries:
CCLeaner
Abexo

What do you use and what do you think are the best?

In the past I have tried AntiVir, MacAffe and Norton and did not like too much also AVG which is crap

I need some good programs to speed up my computers performance because it is very slow.

I need programs like anti-spyware programs (or will AVG internet security paid) do it, it has anti-spyware) and malwarebytes (does AVG internet security paid have that?).

Also just normal cleaning programs to make my computer faster.

After the scan with avg it listed 200+ registry issues but stated it sould only clean like five. Is having 2 different scanners harmful to a computer (just having them on there)

What is this "About Blank" page that pops up every time I close my internet explorer?..How can I get rid of it for FREE?? I do not know what it is and it is really bugging me…I have SUPER SPYBOT, SPYWARE DOCTOR, AVG, AND WEBROOT (window cleaner)….I run them often and they don’t seem to fix the problem…Is it a virus of some sort?? Please help me to get rid of it…THANK YOU!!
