When is the best time of year to buy a computer?

Still

On another note

Why not try a couple of things first -
Uninstall AVG (That was a bad idea)

Download MALWAREBYTES (Make sure you click 'DOWNLOAD LATEST VERSION')
http://www.filehippo.com/download_malwarebytes_anti_malware/
Open malwarebytes and goto UPDATE and click 'check for updates'. After its updated goto SCANNER and click PERFORM QUICK SCAN then click SCAN
Remove everything thats found (needs to be ticked)
Post the COMPLETE log here AFTER youve deleted everything it finds
If anything was found then do the exact same but run a FULL scan


reboot

Download HIJACK THIS (Make sure you click 'DOWNLOAD LATEST VERSION')
http://www.filehippo.com/download_hijackthis/
Click MAIN MENU then DO A SYSTEM SCAN AND SAVE A LOGFILE(Takes seconds) then post the log so we can see whats running
(do NOT do anything else with Hijack but scan and post the FULL log)
If you get a message that you cant write to the hosts file then Press the SHIFT key, and whilst holding it RIGHT CLICK and select RUN AS (admin)
