I did a rootscan by avast with settings "fix automatically" ie. Repair/move to chest /delete... During it many files in system32 were also detected as adw-gen n so on.. But none of them were repaired but most deleted n se chested,,, after that when i restarted my laptop (hp compaq) it failed to start then i did "last known good configuration" n started but since my eventlog service is not functioning.. My wlanautoconfig, n many other aervices and their dependent services cant run,,, along my system speaker, network adapter , peripheral bth device e.t.c .drivers are missing and cant find by "search automatically"option n in some says the driver is uptodate but is not working peoperly.,, i restored and added exception in those in chest bt no improve.,. What can i do to solve it?? m sorry i hadnt backedup/created reatore point of system.. Is the new windows installation only the solution?
