I got a phone call from people impersonating some kind of tech support company. I was redirected to http://www.ammyy.com where I downloaded an .exe file which granted them remote control of my computer, and they then proceeded to use said program to run a scan for viruses, spyware and corrupt files. it was only when they started asking for money that I realised it was a scam. After a brief exchange of insults the phone call ended.
If the scanning software (which was removed by the scammers) is to be believed, my computer contains a large number of corrupted files.
I would like to know A) what is a good way to deal with these files and B) if there is a risk my system has been infiltrated on a more permanent level by these scammers and if so what can be done to combat this problem.
Your help in this matter is greatly appreciated.
