Hello, I was hoping someone can help me. I purchased a new laptop for my son, and I'm trying to fix his old one to pass on to my youngest son. Over the last few months he's hardly used it and it's been running without antivirus, so I installed Kaspersky pure and it found 19 Trojans! It has deleted and disinfected those but the laptop (a compaq presario cq60 notebook with vista service pack 1) is still running extremely slow. I'm not very upto date with pc's and I'm unsure if I should trust Kaspersky to have fixed the trojens? I have read elsewhere that I should get Hijack this and save a log, which I have done, however when I run the programe it gave me the message-for some reason system denied access to hostfile.- and it saves the log as windigs??. So I can't save and post a log, sorry for the long post :-o I would also be open to restoring the system right back to factory setting but have no idea how to do this. I am willing to follow directions and advice, any help would be greatly appreciated. Thank's in advance. Belinda.
