Antivirus NEVER finds anything

[Whitebeard1]

I have had Qihoo 360 Antivirus on my other old computer for about 2 years. But it had never find anything at all. Why is this? I thought there must be at least one virus or problem in two years. But it never found anything, except false alarms(on programs and files that are obviously not a virus or problem)

If you are sensible you'll never really have a problem with viruses - I myself have also not received a warning about a genuine virus in years!

That said, I have never heard of 'Qihoo 360 Antivirus' and as a result I can't imagine it being of the best quality.  You may want to consider replacing it with something more well known such as "Microsoft Security Essentials" or "Avast"

Qihoo was actually meant to be pretty good and did well in tests, but I heard they sold out not long ago so not sure if that's still the case.
As camerongray says, there's no reason to be concerned that your antivirus hasn't picked up anything, unless of course your computer is acting strange.  I haven't had a warning for years either, barring scanning HDDs which I already knew were infected in order to clean them.

There is very little viruses around these days. Most of the stuff I clean is malware and spyware.

Hey, thanks for the replies. I just did a scan with another virus tool from Kaspersky, and it detected 8 items.
Also, I have been getting some things like ads and pop ups on my PC.
Qihoo 360 have done well on the tests, and it also done well on my other PC...but never detected anything on this one.
I'm thinking of getting MSE instead.
Thanks.
