Two days ago I was getting really annoying adware that played ad sounds in the back ground. I did a google search and with the help of a friend I got rid of it with this guide posted on malware tips: http://malwaretips.com/blogs/remove-random-audio-ads-virus/
I have dual start up and with windows 7 and windows 8 (trial). So I ran malware bytes and it would shut off my computer in windows 7, I then downloaded malware bytes in windows 8 and scanned both hard drives and it would stop responding. I went into safe mode windows 7 and ran all those programs (listed in malwaretips), and none of them found anything. Afterwards I downloaded avast in windows 7 and it would crash. I went into safe mode and ran avast went afk, when I came back my computer wasn't in safe mode and the adware was gone. I ran malware bytes quick scan which found some stuff, then I ran malware bytes anti root kit which also found something. Then I ran all the programs again this time not in safe mode to make sure I didn't have any malware, none of them found anything. Just to be safe, I decided to do full scan with malware bytes and my computer crashed. Note, it didn't shut off like before but everything would just stop responding. I was forced to manually shut off my computer, then I tried running a full scan with avast. Avast was finding some things but then my computer crashed again. So I manually shut off my computer and then went into safe mode to run avast and it would freeze up.. Then I went into windows 8 to do full scans and they went fine..
So, i'm not really sure if my computer is still safe since when I run avast quick scans in windows 7 it finds things then my computer crashes. I don't really know what to do. I guess I'm going to try running avast quick scans and all those programs on malware tips again. Thing is, I don't have the adware and my computer runs fine..
