I am running Windows 7 64 bit on a Toshiba Satellite L655. I consider myself somewhat computer literate, and have dealt with about 4-6 serious malware problems in the past on other machines. I am truly stumped on this one however.
About a week ago I noticed small things happening to my computer. My homepage and other preferences were cancelled out in Chrome and the volume control on the toolbar disappeared. I've seen that before in other issues. A few days ago, my wireless card stopped working while I was browsing. It was as if my computer couldn't find it or recognize it. I could connect with an ethernet cable.The computer became pretty slow at times at this point. The computer would sometimes freeze up for a second and the sound would get strange. I ran Malwarebytes, CCleaner, and Hitman Pro; they tossed a few cookies and that's all. I did a disk defrag and did a hard reset(I think). The volume control returned but Chrome preferences were still missing and the computer still ran slowly.
Just now, the computer completely crashed and showed me a blue screen with a serious sounding message I can't recall. zI rebooted with no problem and the wireless card is currently working.
This may be unrelated, but I downloaded utorrent a few days before all this but did not use it and uninstalled it. I also suffered check card fraud last week.
Sorry to be so long winded. I would appreciate any help.
