I have a fairly new laptop with Win 7; I also have Microsoft Security Essentials which seems to be doing it's job. Therefore do I need Ad-Aware? I've downloaded and installed it but immediately Windows Live mail couldnt connect but then it was ok a few minutes later. Not sure if the 2 are connected. Is MSE enough?
I guess you are finding Ad-Aware a bit of a pain as I did. It used to be good but when it was updated it started causing me problems.
To answer your question. There are other options which you could install which will provide additional security and which may cover the bits of malware which may otherwise get through. To my knowledge there is no single package which will cover all possible loopholes.
I would suggest you consider something like SpywareBlaster (free) click here which blocks various nasties and is active. You could also use Spybot S&D (free) click here, SuperAntiSpyware (free) click here or Malwarebytes (free) click here all of which you can run to scan your system for anything that may have got through.
