something's up with my PC

hello friends need help from ya..

I think something is up with my computer(windows ultimate x64, virus guard:kaspersky).. The recent scene is when I try to run Windows Defender it shows the window just for a second and disappear.. then I downloaded the Microsoft Windows Malicious Software Removal Tool ,when I double click on it, it shows self extracting but doesn't run.. no error reports and nothing just not running.. I have another symptom that is sometime when I click on a google search it directs me to a whole new page which is not related to any of my search results..(to site: beboo.com or something like that)..
So guys, what should I do now.? I don't know what to do..But I can follow what you guys say and figure out whats wrong with my System.. Sorry for my English.I know it's not very good..

thanks in advanced.

Download & install Malwarebytes Antimalware, update it, then do a full scan.
If it wont install or update, boot to safe mode with networking & do it there.

ok I'll try.. thanks

Do you think these are the reasons for above symptoms ?.. Do I need to do some other things? Any way thank you for helping... :)

Those could have been the source of the problems. Have you tried running the tools that didn't work before, since the MBAM scan?
I recommend that you download SUPERAntiSpyware free, install & update it, then do a full scan.
I have both MalwareBytes & SUPERAntiSpyware installed on my system(in addition to my AV) as on-demand scanners & they haven't failed me yet.
Also scan with your resident AntiVirus, you can never be too careful when it comes to malware.

google redirect problem seems solved.. but I still windows defender fail to start.. just show its interface and disappear.. I'll try SUPERAntiSpyware.. and let you know.. cheers

What is your security set-up..?

You might want to keep both MBAM and SASpy. Add Sandboxie it's >$40 and a keeper.

-- I agree there. Very nice second opinion apps. :)

i am having the exact same problem he described here:

he recent scene is when I try to run Windows Defender it shows the window just for a second and disappear.. then I downloaded the Microsoft Windows Malicious Software Removal Tool ,when I double click on it, it shows self extracting but doesn't run.. no error reports and nothing just not running..

I also had the redirecting problem, but i think i fixed it thanks to tdss killer. Any ideas?
