SpybotSD

Spybot Search and Destroy is absolutely free, they ask for a donation but it is not mandatory.

More information at Wikipedia:

some free antispyware are

SUPERAntiSpyware
Spyware Terminator
Spybot - Search & Destroy

if your looking for another virus scanner try avast or avira.

if you need to remove avg, use the removal tool

Avira Antivir is free and offers both antivirus and antispyware protection

you can also run scans with superantispyware for a second opinion - free too - it doesn’t conflct with avira

Both of these are free Avira AntiVir free edition. quick scan times, low on system resources, updates daily, and has an over 94% detection rate, ad superantispyware free edition to it which is great at finding trojans and other crap with these you should be fairly well protected.,

Malwarebytes and SUPERAntiSpyware are the best anti-spyware applications available (you can have more than one). Other free anti-spyware programs would be Spybot Search & Destroy, Adaware, AVG Anti-spyware (formally Ewido), A-squared, Spyware Terminator and SpywareBlaster.

I strongly recommend using Firefox as your primary Web browser, It is safer and better than Internet Explorer. Get the add-on NoScript for Firefox to prevent click-jacking. The AdBlock Plus extension will allow you to surf virtually ad-free. I also recommend CCleaner which is a free system optimization and privacy tool.
