If you want antivirus with network shield and email scanner, I suggest using Avast free:
If you want antivirus without the above stuff, I suggest using AntiVir free:
Both antivirus program is light to use and free for personal use. They are known to have good virus detection.
Note only that if you choose to install Avast, do not allow installation of Google Chrome which is not needed in using Avast antivirus. Allow only the installation of Google Chrome browser, if you want another browser.
Ad-Aware should work along with AVG, Antivir or Avast but you need to ensure that the antivirus engine in Ad-Aware is disabled. It is not recommended to run two antivirus program.
I just bought a new laptop. I need to know what kind of protection I should use... I read about AVG, Adaware, and others.. but not sure which ones complement or create conflict with each other. Any ideas?
