BULLGuard int -Viruses?

When I bought my new computer it had Bullguard pre- installed on the computer as an viruses & spyware software, it was on for a 3 months trial, now there is ome month to go and it is asking me to buy it, but at �48 for a year, do you think that is to much to pay, or has any one else got it on and what do they think of it, Thank you all for any help.
