Are downloading antivirus systems just as good as the original ones?

I want to get an antivirus system so will downloading the free trials show me a sample or will it further damage my computer? I want to download the Norton Antivirus 2007 one for 90 days. So will it cause errors?

For your anti-virus needs, I would suggest Avira AntiVir庐 PersonalEdition Classic. It has excellent heuristics, a virus detection rate that is better than most "paid-for" anti-virus programs and is light on using your computer's resources. And did I mention that it's free!

Download here:

BTW, Avoid the free version of an anti-virus called AVG, it is wildly popular, but it has horrible virus detection capibilities.

Enjoy!

Just download and install the free AVG antivirus program. It works fine. It can be downloaded at the below link. Good luck.
The downloads like Symantec Antivirus are just fine. The 90-day trial is for the virus definitions; it doesn't mean the antivirus program is crippled until you buy it. However, after that 90 days, you won't get new virus definitions so you won't be protected unless you buy the subscription.

There are several other free antivirus programs such as AVG and Avast, and they have been known to do a great job without putting a choke-hold on your operating system like Symantec.

I haven't heard of the two applications you mentioned, but they shouldn't interfere with the antivirus side of Symantec. However, if you have Symantec's security suite, it comes with a firewall already, so having two of them will more than likely create an issue. Be sure you download just the antivirus.

Good luck!
