PCGuard is not free unless you are a high end subscriber. I am on 2MB which is the basic one and PCGuard support has been withdrawn. Fees are as under:
Anti Virus £2.00
Anti Spyware £2.00
Parental control £1.00
Whole pakage will cost £5.00 per month( £60.00 a year) which is far too expensive then stand alone pakages in the market. There are some execellent free programs available for download.
PCGuard will have problem using IE7. Which they haven't fixed so for but there is a work arround.
