Carolyn thinks she got attacked by a virus. MalwareBytes says there's over 174 viruses on her machine. Leo says there might not be. There may be malware on it, but sometimes Malware Bytes gives a false positive on cookies and calls them viruses. She'll also want to be sure that she got MalwareBytes from the >official MalwareBytes site. Carolyn really should just make a recovery, back up her data, wipe the drive, and then run the recovery utility. It's the only way to be sure that she's free of viruses.
