hi, you can download "Avast" from www.filehippo.com . its a good safe site. after installing Avast it will ask if you want to do a boot time scan, you can if you wish, it will scan you hard drive 1 time before windows starts up, set Avast to deleat or move all things it finds, when its done you pc will reboot it self.
up date Avast if it needs it, but it will update it self when its online any way, and whan your at www.filehippo.com get SpywareBlaster. all ways run it at windows startup and keep it updated, it will keep your pc off websites with bugs on them. good luck.
