I am attempting to clean my daughter's laptop. She was running an expired pre-installed version of MacAfee when she clicked on a link for source data, given to her by her professor, to complete an assignment. Shortly after clicking, the PC was full of advertisements and finally locked up. She brought the laptop to me to fix. I run Malwarebytes Premium on my PC, so I attempted to clear the PC using MB. I have tried running Malwarebytes several times and it always gets stuck during the heuristic scan. Originally there was 1300+ PUP detects. I tried running in safe mode with the same results. I downloaded and installed an older version of Malwarebytes it was able to complete a scan and remove most of the PUP detections. I updated to the new version of MBAM and it still hung on the heuristic scan. I have run scans using MS Defender, and Kaspersky and both scan the laptop as clean. I downloaded and attempted to run Malwarebytes Anti-Rootkit but it also hung, even when run in safe mode. I performed the MBAM clean removal process as instructed on the forum, and the scan still hangs. My gut tells me this laptop is infected. The laptop is a Dell Series 5 UltraTouch, running 64bit Windows 8.1. I have attached the FRST.txt and addition.txt files, and the CheckResults.txt Please take a look. I would appreciate any help you can provide. Thanks. Addition.txt FRST.txt CheckResults.txt
