This program is worse than any virus you might get.

I won't take your expression literally (I've seen some pretty nasty malware) but yes, Symantec stuff is known to be troublesome, buggy, extremely hungry on resources, and on top of that there's the annoying fact of having very slow and sometimes poor virus signature releases when compared to the Antiviruses which are generally respected in the security community (such as NOD32, Kaspersky, F-Secure).

Every security suite/product may be troublesome, but I have had much more trouble with Symantec products (and much more infections) than with any other non-free antivirus.

Edit: my personal position on antiviruses is that they are flawed by design. The now late Holy Father, author of one of the best rootkits ever (Hacker Defender), had a similar position. However for those who aren't savvy enough to use a proactive approach (and that is the absolute majority of users) it's a form of necessary evil.

I agree on Norton though. Used to have it, eat resources, was quite annoying too, popping up for no reason at all.
When I call support for my internet, if it doesn't work, first thing they say is: do you have Norton Anti-Virus? If yes, remove that first and get AVG or something.

Basing my judgement on free antivirus comparisons and first-hand experience I'd say "or something".

(Precisely Avira Antivir, which has much better recognition although it has advertising on startup and no mail scanning in the free version. However if you don't turn off resident protection it still greatly outclasses the free AVG's detection rates on malware.)

Now and then I also use ad-aware. But didn't run it for some time now. And I think I'm gonna reformat my PC anyway, it's so sluggish and slow, I just think there's something wrong with it. And I fiddled with a lot of things and stuff starts acting up. Just a fresh install could do the trick!
I bought it from an older man, who wanted a laptop. But he never really looked after the comp. It's been formatted before I got it, but still... It's not how it should be. Lots of commercial stuff on it from the store he sold it to and we bought it back from.
And if I do it, I don't have to experience the difficulty of deleting all the pictures of my ex myself.

HELP, someone sent me a setup and i saved it, but later on they told me it was infected with a virus. What should i do?

Haha.
