Well, There is no free spyware removing tool available, but you can get a trial scan before buying any software actually. I’m using XoftspySe which is available here. I know you said that you get a trial scan. Try this, i’m sure it will help you.

Try Sophos …I use it…and hv never come across… any virus problem with it yet!!

Get Spyware Stop
It is the most advanced and comprehensive spyware removal product on the market.
Remove Spyware, Adware, Trojans, Dialers, and Other Dangerous Parasites.

Kaspersky it’ll give you great protection, it’s very reliable, and has some nice sound effects

avira antivir personal - free antivirus and advanced windows care personal

I had the same problem and honestly dude, I had to buy a program but it worked and I have the product forever now so i can use it whenever.

remember those “free” virus removal programs are only there to bait you into buying the real product anyways

I went with the NoAdware program. I tried their free trial and then ended up getting it. you can check it out here.

good luck!

The best spyware and virus protection is ESET NOD32 Antivirus! AVG is good but it is suitable for computer expert, Norton has too many rubbish function so slow down your computer, Malwarebytes is a good tool to scan virus but it is no real time protection.

Lots of personal preference in this category. Starting with free as a major goal, the reviews I’ve read on-line rank Avast (http://www.avast.com/eng/download-avast-home.html) and AVG 8 (http://free.avg.com/) as the best. I use AVG. I’ve recommended both.

I would also commend the previous recommendation on Spybot 1.6 S&D (http://www.spybot.com/en/download/index.html).

All three products are easy to use, easy to maintain, easy to install. And free.

If you want to pay, Spyware Doctor with AntiVirus 6 and Webroot AntiVirus with AntiSpyware 6.0 are pcmag’s Editor’s Choice products, and run under $40. They scored well above the other products mentioned above

One last thing - I still have dozens of clients using Norton without a problem. And I can relate a horror story on every major AV product out there, often more the fault of the operator than the software.

Good Luck.

Avira AntiVir free with superantispyware and spyware terminator; I also reccomend comodo firewall! a great FREE security package! all are good and i have every one on my laptop! also get a safe web browser like firefox and site advisor such as: web of trust (for firefox), or mcafee site advisor. from there you should be super protected since comodo firewall, super anti spyware, and avira are top rated with highest detection rates, also spyware terminator gives real time protection and is great!

Good Luck! vote as best answer! please!
