AVG 7.5 google it then free version and locks virouses in a valt worked on my pc. good luck
yeah try McAfee, Norton, or Kaspersky, those usually have trial programs that'll clean your stuff up. If not you can always reformat your computer again, just save the things you need on an external hard driver preferably atleast 160 gb incase.
try Kapersky(not free)... or

Avira AntiVir (best free antivirus)

use firewall (i recommend Online Armor) and have a spyware scanner back up (i.e. Spybot S%26D)

for junk files try CCleaner

First remove all unneeded programs cause this thing could be hiding in one of them and also just too clear out space on you comp, i use revo uninstaller to do this because it removes all traces that a regular uninstall can leave behind. next ccleaner at www.filehippo.com for junk files
