Startup And Computer Slowed After Instaling Drivers,Programs,.Dlls etc

Hi all,i recently had an 0xc000007b error with a headset software.I tried everything on the internet to solve problem including uninstalling and installing .net framework, visual c++ (all versions), some .dll s both in system32 and syswow64,reinstalling drivers and some other things that i cannot remember right now.After those countless things my perfectly working fast and sound laptop slowed like an 10 year old pc im having issues both at boot and in normal use.Before this incident my windows was booting apprx 1 min.But now it takes 450 to 500sec to open.Im suspecting a virus or a malware has got into my computer.Meanwhile im posting this im running scans with both bitdefender 2014 and malwarebytes
.My pc specs are
Intel i7-3630QM 2.40
8Gb ddr3 ram
Nvidia GTX670 2Gb
Windows 7 64 bit
And Here is the event log of the latest boot
