Hello sophialin!:-) It depends on the type of virus and threat actually. There are different types of viruses on internet. Most of the time, they are adware. When you visit some sites they get downloaded along with other stuff and get installed. What they do is, they see your browsing habits, the sites you visit and type of things you do on internet. And, as they are constantly retrieving data, your computer gets slower than normal and its performance gets deteriorated. Plus, you would start getting and seeing some unsolicited emails in your email inbox. So, the first sign of such types of viruses, or whatever you call it, is that your computer slows down and you get many number of emails/spam. There are other viruses which are more specific; they try to get your personal information from your system and cash on them in different ways. Then there are those which hackers make just for fun. In these types of viruses you will see your computer malfunctioning or even doing some funny tricks by itself. The best thing is to have some good multi function Anti-virus installed on your system which analyses in real time and also stops further threats. One important thing is to note that many free anti-virus or virus scans themselves try to get information from your system and either deliver it to some companies or they install programs without your consent. So, it is important that you check their TAC numbers before installing them. Best of luck!:-)

I think the obvious thing is your computer will be slowed down. And your computer will crash due to an unknown reason. If you press Ctrl + Alt + Delete and check the process. If you find some unknown and strange programs running, then perhaps your computer is affected by virus.

Hello dear sophialin. I have to say that my computer has been infected for a month and it has not been fixed yet though it has been sent to the computer shop to get the system reinstalled. The viruses are still there. It seems that the viruses attack my computer every now and then. I think that it is mainly because I do not have anti-virus software that they are so crazily attacking my computer. I am going to do something again for this when I have my days off. My IE is frequently changed by those evil viruses. It is so boring. I am really very angry with them.

well since I have virus protection my AVG will let me know at once and it will either clean it, delete it or put it in quarantine in the vault making my machine completely protected from virus. if you find you are getting messages telling you your emails cannot be delivered and you find that you never sent the messages it could be a sign that your machine has picked up a virus. the best thing is to invest in a virus protection program for your computer mine is free AVG

I often wonder the same thing. I know that my computer has been running very slow, but I don't know if it is the result of a virus or not. I do run an antivirus program, but it never finds anything. It may be a matter of too little too late for me. Any suggestions?

running slow is often caused by a number of things like not having enough memory or from having too many programs on at the same time.if your antivirus program shows no virus I would think you are really virus free.

I had actually installed another program that was suggested by someone else in another thread and it found several things that had been installed by the school when they reinstalled the operating system recently. So far, it seems to be running better. Thanks.

Viruses vary depending on the strength they could affect our system. The higher the abilities they handles, the more obvious they seem. Some virus can even shut down immediately your pc. So, the more the unusual performance your pc does, the higher the chance of virus attacks.

1.First and foremost is slow down of your system. 2.Some pop-ups will be keep on displaying. 3.Some websites will be blocked. 4.Every folder will be opening in new window,instead of own window. 5.You cant able to see hidden files. MORE THAN THIS............. Just simply insert any removable media like pendrive or floppy drive search for *.inf or autorun.* removable media If you found anything which is hidden (If you didnt copy it manually) Surely you have virus in the system!!!!!!!!! You cant able to access some system accessories like system restore, regestry editor, task manager,msconfig,grepedit

I like to check every day for a virus! There are so many threats that having a good computer virus program is important! I scan each download and also scan the whole computer on a regular basis! The first sign for me is the computer slowing down, or some other glitch that catches my eye!

the symptoms are that your system is running slow, there are lots of pop ups from other websites u need to install a internet security that has a pop up blocker that. also u should install an anti-virus on your computer and run it everyday to make sure your system stays clean. viruses are easy to get into your system when you visit websites.

usually you will notice the internet not responding as well as it normally does - you might see pop-ups like crazy. Sometimes the computer will be slow, freeze up a lot... the best thing to do is get a software like AVG (free) or Trend Micro - both will help remove viruses and prevent them. You can also type in "msconfig" in the run command and look at what programs are starting up everytime you turn on your computer. I found I had 3-4 viruses my spyware software missed - you just disable them & no more virus - but since you can really screw up your computer doing that, i wouldn't mess around with msconfig until you really do some research on it.

As you know computer will become slow and you can see some extra suspicious processes running in taskmanager. You can also see some new startup entries and also to services. These viruses mostly run from system32. Computer takes longer time to start.
