How do we get rid of lots of Adware and is it a possible Trojan virus?

I have some programs on my computer which i use to try to find stuff…

Ad-Aware SE Scan Results = NOTHING.
Symantec AntiVirus Full Scan = NOTHING
SUPERAntiSpyware Full Scan = Adware.Vundo Variant [5 items]/Rel and Rogue.Component/Trace [1 item]

I have quarantined, deleted, rebooted and repeated these steps many times but every time I scan, there is always more.. :(

A friend recommended I download AVG which is like free.avg.com. I downloaded this and am currently running scans with it as well.

Also, is it bad to have AVG and Symantec Norton Antivirus at the same time??

Lastly, another rrecomended software is Malwarebyte’s Anti-Malware (MBAM) which is supposedly good for getting rid of these problems. Can this run with other antivirus software?
