I run windoz 7. Awhile back, during a windows update, bit defender flagged an update of svchost.exe. I mistakenly clicked avoid... and not sure what bit defender did with it. Since then, my wireless internet connection fails after about 1 minute into boot up, rendering my PC absolutely worthless. I see lot of register repair offers, they do nothing and most want money; which of course one does not know if it would even fix the problem. Letters to companies are lame and unresponsive. I suspect a crupped svchost.exe service app for my 64 bit windos 7 system.
What is the best way to fix this problem? Need specific cookbook instruction because I am a computer virgin.
