I apologize for not being more clear. TechSpot is an excellent place for getting help of all kinds from reading your minidumps in order to help one figure the cause of BSODs, hardware issues, etc. Many, many novices/first time posters go there and a significant number of contributors have as much as 30 years or more tech experience who help them. (And, no, I don't get paid by TechSpot!
But I do read minidumps over there)
Sometimes infectious problems go well beyond a mere scan and extra help is needed. The link I provided was the Virus and Malware forum in case Variol needed further help. The stickies at the top help guide in the process and if he doesn't understand how to go about doing certain steps the contributers are more than willing to help. One example is mflynn has 30 years in the business and he has helped a lot of people.
As for scans a mere googling will easily find ESET's NOD32 scanner as well as BitDefender's scanner. I've used both to help clean out heavily infected machines; a lot of tech people use them. NOD32 is one of the top antiviruses in the world along with Kaspersky (best detection rate in the business), Avast, and Avira Antivir.
Another excellent software that deals with rootkits, Trojans, and other, more malicious, software is SuperAntiSpyware (SAS) and its free version is really good though if you use the free you have to manually update their definitions.
Just my 2 cents worth.
