What is happening with AOL? I have been having lots of pop ups, slow computer and AOL telling me they are having problems? My computer very slow?


Is you computer slow when using software offline? If so, it is either AOL or your internet. Don't judge the speed strictly by going to AOL. Go to Speakeasy Speed Test and test your internet speed. If that shows your internet is running at the speed you are paying for, it si AOL having trouble. You don't say which browser you are using, but most browsers have an option to block pop-ups. Make sure it is on.
Run a virus scan on your PC to see if it is infected. Also defrag your hard drive to speed it up some.

What is a Virus and how do I know if I have one ?


There are some obvious symptoms that your computer will develop when it gets infected with a virus. But the first thing I have to mention is that if you had a decent antivirus program installed on your computer you would not have a problem. The virus programs now days are fantastic in crushing any chances of a viruses infecting your computer.

What is a virus?
A virus is a small program that gets into your computer undetected in order to cause havoc. This small software program has either been developed because the author enjoys causing disasters for other people or sometimes for monetary gains. Sometimes a virus is packaged in a file that is called a trojan virus. It is disguised as something else, and once it has gained access to your computer it then releases its intent.

How does a virus get onto my computer?
The people that develop these viruses are constantly finding new ways to infiltrate your computer. When one door shuts, another one opens for them. However the most common ways to get a virus on your computer is through the internet. You might download a file that contains a virus, or maybe you might open an email that has one attached to it. Sometimes even visiting a bad website can infect your computer. The worst one of all, however, is when people download illegal cracked software. This software has usually been taken apart and repackaged with a few extras attached. Maybe you download music or videos from the internet. How do you know you are actually downloading the file you intended to. The file may be named to deceive you, and once you open it you will release the virus.

How do I know if I have a virus or not?
If your computer has been infected with a virus you will quickly see odd signs that it exists. Weird things start happening that you cannot explain. Files might move around, odd error messages may appear, programs might start to fail. For example if your virus scanner program stops working then it could have been disabled by a virus. With all this action taking place in the background your computer will also start to run slow and seem like it is busy all the time.
When browsing the internet you might find that you will not able to visits the pages that you choose. You will be redirected to different websites. You computer might also be sending emails to everyone in your contact list without you knowing.

What can a virus do to my computer hardware components?
People think that a virus simply attacks the file systems of your computer, however this is not true. Some viruses are designed to damaged computer hardware components until they are ruined completely.
Many people will argue that a virus only infects software, however all hardware is controlled by various types of software. Infact the entire computer is controlled by BIOS which is software. BIOS controls the temperature of the motherboard. What if a viruses only purpose was to change the temperature control on your motherboard. The motherboard would overheat and fry itself.
In the old days viruses used to be developed to set the read speed of a floppy disk drive to speeds beyond its capability. The Floppy disk drive would overheat and fry from being overworked. Now days Windows Vista has a service called Superfetch that searches your hard drive, finds out what you use the most, and makes it available for you.. If you made a virus to control Superfetch, we could have a serious problem. Most Vista users already have Superfetch disabled on their computer. A virus could enable it, tell it all files are important, keep it searching non stop, and fry your hard drive that way. Now I can here someone saying "yeah right, not with all the security we have around today". Well you should never underestimate these guys who develop viruses. They can work around anything.

What should I do if I get a virus?
If you suspect that your computer has a virus, scan your computer asap with an antivirus program. If you do not have one or yours is not working, download another one, or get a free scan using the free online virus scanners, such as :-
Symantec Security Check :-
http://security.norton.com/sscv6/WelcomePage.asp
or
Kaspersky lab :-
http://www.kaspersky.com/scanforvirus

There is no guarantee that these free scanners will cure your computer but they might just confirm the fact that you actually have a virus.
If you find viruses but cannot remove them you will need to take your computer to a professional before you lose everything. Another option is to format your computer which means you loose all the files on it and re-install a fresh copy of the operating system. You can backup your files first, but please be aware that they might be infected with a virus also.
If you have scanned your computer, found viruses, and successfully deleted them, then now is the time to buy a decent program that will stop this from happening again.
Do not continue to use the computer without taking action because the longer you leave it the further the virus can spread.
What file types commonly contain viruses when you download them?
Lets face it, downloading is a dangerous business, especially when you have important files stored on your computer. Any file you download can contain a virus. My rule for downloading is to ask myself "Do I know and trust this website I am about to download from?"

Here are a few examples of common files that could contain viruses :-
EXE FILE: If you download a program or anything that requires an install file then it will be an .exe file. When you press on it to install to your computer you could be releasing a virus.
ZIP FILE: People download zip files from the internet that contain any other file type and you will not see it's contents until you open it. A zip file might have an exe file in it.
SCR FILE: Free screensavers for your computer. They always have something bad in them. Sometimes adware or viruses.
DOC FILE: A Microsoft word document can contain macros and small scripts that are viruses.

If you haven't got antivirus software installed on your computer, then refer to : http://support.microsoft.com/kb/49500 for Microsoft recommended antivirus softwares.

REMEMBER : PREVENTION IS BETTER THAN CURE

My computer is infected


Well that sounds like you got a virus disguised as an antivirus, those are pretty common, in that case you can erase it, but the slow load on your computer will remain, if you get a virus usually there is a way to delete them but the consequences will remain, in that case you can reinstall windows, that will be better that just removing that virus, Best regards, Luis!

Running slow pop ups all the time


You more than likely have an infection. The problem is, removing an infection is a lot easier said than done. While your computer is running, so is the virus. And it would be like attempting to delete a picture, while you're looking at the picture. The computer will yell at you and tell you the file is in use. There are tons of guides on the internet as to how to easily remove a virus, but I will give you the short of it. If you don't have any antivirus active protection; Microsoft Security Essentials is free and pretty good. Download and install that. MalwareBytes and Spybot S&D (Search and destroy) are both fantastic at virus removal, but don't have active protection.
Download the three of these, install them, then restart your computer. As it is turning on, press F8 and then navigate to Safe Mode. Run all three scanners (not at the same time, and you might have to restart in between) and your computer should be much better off if this was the case. If this doesn't do much for your situation, at least you now have active antivirus protection.
Lastly you need to be VERY careful about the popups. Many of them advertise that your computer is infected and to buy "their" antivirus software. The problem is, that software is a scam and you will lose your money. And remember when you have big issues like running slow with popups all the time, you can always take it to a local tech shop if you're not comfortable with doing the work yourself. However this kind of repair can cost up to about $200.

After use internet my pc,s speed very slow.


Your computer may be infected with a virus. Are you running any anti virus software?

Do a simple scan of your machine using anti virus software - If you have none installed, download and install this.

I have included AVG as its free.
http://www.avg.com/

Log off from the internet and run the scans - if you haven't run one before this may take several hours.

The clean up should remove any old entries and also detect any virus which may be slowing down your machine.
