Nope, that's probably a spyware or something else. There isn't any magical function in your computer that calls for an antivirus when it's infected. If anything, it might also simply be internet advertising.
Avast! Trust me on this one guys, just google for it. Its free and it does an excellent job, much better than AVG. It has an onaccess scanner as well and can even help prevent you from going onto harmful sites. It also updates automatically on a daily basis. Overall its been really good to me and has kept my computer clean for a long time. =)
Also another good spyware program is Spybot Search and Destroy. This has an immunization program which also blocks even more harmful sites.
A final porgram i wanna mention thats also good is CCleaner. Its not really an antivirus program, but it does a wonderful job of removing all the junk files that build up on your computer, which overall can help in prevent some viruses even though thats not really its main purpose.
All three of those can be found via google and are all WONDERFULLY FREE!!! So just give em a shot, and with em your computer's should be running smoothly.

Post above has it spot on, everyone who asks me for an anti-virus program, I always say avast! I've practically made it my life mission to install it in everyone's houses.
According to me, AVG Antivirus is the best because it detects mostly all the Virus and delete that virus.
AVG AntiVirus is really a nice antivirus i using it from last 2 years and because of that my PC run speedily....
hmm really with a lot of antivirus,trojans,malware... we need antivirus. But I get dizzy every time I would change to a new one. Some would recommend this and that.. but recently the one I had was ok, it was AVG. It's good. I got Kaspersky now, it stops my computer sometime...
Well honestly how many of you have actually caught a virus that often? I haven't caught one in years. Spywares are the new thing, viruses are really only much of a threat to the user who clicks on stuff he/she doesn't know. Very rare are the cases where a virus literally infects your system without you actually initiating something(downloading something, opening an email etc).
I honestly wonder how people can claim an antivirus is better than another unless you've caught THAT many viruses to compare lol
But how do you know Avast! doesn't detect one when another one will? Honestly the only way to truly compare is to have 3-4 different ones running and then see.
I can say this because my friend is a programmer and he's developed viruses and spywares before. There are sites where you can test to see against which firewalls & antiviruses your "creation" is effective or not. It's not a question of "which is better" so much as sometimes they just operate or behave differently. I mean, I know he made one that wasn't detected by some free and paying antiviruses yet the damn Windows antivirus got it. Problem much? or did Windows suddenly get a really good antivirus embedded into it and I wasn't aware?
Some antiviruses use signatures, others registry entries, others use behavioral patterns and some even use input/output filtering t determine if something is a virus. It's just a question of mechanics in terms of the antivirus vs a particular virus that's all.
Like I said, viruses aren't that much of a common trend anymore ANYWAYS.
Oh I'm not arguing that. Avast is a good antivirus, but IMO they're close to the same thing in general. A few slips here and there will mostly be because of the mechanics of a certain virus when pitted against a given antivirus' methods rather than the strength of each.
Btw Avast doesn't load behavioral patterns I can confirm this much. Only 2 antiviruses I know actually do that. It's a new technology and it's quite annoying and somewhat long to implement correctly, but offers some of the best protection.
For the record Trojans and Worms are both types of viruses. Spywares are another type of issue and the most common ones these days.
As I've said before, the best protection against viruses is knowing what you're doing. Probably around 80-90% of viral infections happen because you as the user did something to initiate it(open an unknown email attachment, clicked a link, downloaded something etc). Rare are the cases where someone voluntarily goes to forcefully implant a virus into your system.
The antivirus only serves once the infection happens, but prevention is better than treatment.
O I know knowing what your doing helps, and prevention is that best. And thats a reason why I likve Avast! as well because of the On Access Scanner that will actually alert you if you are entering a harmful site. Another program I use is Spybot Search and Destroy which has an Immunization tool in which it protects your computer from harmful sites before hand by building up a database for your browser of these certain sites. As well the key to a great program is one the has updates often which means the people who make the program are staying on top of new types of threats on the internet. I know that during that Conflicker virus scare in April, Avast! updated itself 3 times in one day just to stay on top of this. So you are right, prevention is the key. The matter is getting rid of problems and keeping your computers from having problems, which is what I've been saying all along.
Have tried almost every available anitvirus suite. The lists contains Avast, AVG, Norton, Symantec, Avira, Mcafee, so on. Gave each AV few weeks before I passed my judgment. I went through various problems like virus messing up my system to AV slowing down my PC. After almost months of experimentation, I was finally able to find the best one for me and its none other than Kaspersky. I have been using Kaspersky Internet Security (KIS) for more than year and I think its the best out there. Takes reasonable system resources and the protection is excellent. I am person who downloads various stuff, a lot, and even after several months I never had one virus infection on my PC. Nothing gets passed it. Even IT section at my organization switched to Kaspersky few months back. Our network in office was a mess but now it didn't have a single case of virus messing up the system. So I have my faith in KIS. Do try it.
Does anyone have a good suggestion for a free firewall? I had Zone Alarm until it had a panic attack, couldn't connect to the internet, kept trying, and ground my computer to a halt. Something that doesn't direct me here before I can download would be best :3
