We here at PC Doctor use many types of anti-virus protection software, our recommended virus software that we prefer is AVG virus software. They offer free and paid versions. The free version offers limited protection only - no malware or spyware protection. The paid version does offer malware, spyware, firewall and other protection for your system.
Other scanners we use for specific malware/adware, for non virus related, are Spybot Search and Destroy, and Adaware which offers a free and a paid version. The paid version includes active scanning of your pc as it is running. Spybot Search & Destroy is freeware and it does not have a paid version. There is also Spyware Doctor which is paid for only software which is a more intensive adware and spyware removal. That would be all of the scanners we use on each pc that come in to have spyware and adware removal.
We recommend you brining in your machine for more extensive manual removal as we have all the tools here to run on your machine. The average time of extensive virus removal is three to five business days. Even with expedited service, virus removal cannot be speeded up.
Other recommendations: Notron Anti-virus that offer the same utilities as AVG but requires a higher end pc to run it.
