I recommend creating Spyware/Anti-Virus programs (or a AIO aka All In One). People are usually getting Viruses and Spyware through images with todays technology. Like you could go on YouTube and find a video on how to make a image a Virus.
Hi and welcome,
Comodo is already working in this field. There’s Comodo BOClean, a very effective program designed to complement your antivirus with protection against spyware and much more, and there’s CAVS, Comodo’s antimalware which will be out of beta soon and will include BOClean’s full functionality, it aims at protecting against all kind of nasties.
