At first I thought I was just paranoid, but I'm convinced there's a nasty infection on my PC. Running Windows 10, it won't update, nor will Windows Defender. I have tried various virus removal softwares (MBAM, Hitman Pro, AdwCleaner) but I believe there's still something wrong.
Ran FRST and the log is showing Yahoo Spigot link as my Chrome default homepage? Also seeing svchost.exe files attributed to SysWOW64 in the log, but I don't know if that's normal.
I have also previously tried a clean install, but I don't even think that actually removed everything?! Please help me, am I going mad or is there a problem.
I would really appreciate any guidance.
