Last night,my computer hung up. When I restarted it, window xp doest load and the page goes to black screen and the cursor shows up. I tried running my pc to safe mode with networking. My symantec antivirus doesn't work. I tried running my malwarebytes, it scans halfway, showing 12 infected files and shuts down. The infected files says kriksy/trojan, I think. I tried running eset online scanner and shuts down halfway too. I tried system restore, but it fails. In addition, when I search with google, it automatically redirects the page to another website. When I go directly to a website, it opens a pop up window of another site. Please help!
