Tip & How-To about Computers & Internet

How can I tell if my computer has a virus?

  1. A common symptom of a virus is much slower than normal computer performance. However, there can be other reasons for slow performance, that needs defragmenting, a computer that needs more memory (RAM)

  2. Are you getting unexpected messages, or are programs starting automatically? Some viruses can cause damage to Windows or some of your programs. The results of this damage might include messages appearing unexpectedly, programs starting or closing automatically, or Windows shutting down suddenly.

  3. Is your modem or hard disk working overtime? An e‑mail virus works by sending many copies of itself by e‑mail. One indicator of this is that the activity light on your broadband or external modem is constantly lit; another is the sound of your computer's hard disk continually working. These are not always symptoms of a computer virus, but when combined with other problems, can indicate a virus infection.

6910p really slow


what operating system are you running? How long has it been installed? Do you use antivirus? Did you just install the ram, if so was it faster or slower before? How old is your pc? Common reasons for a slow computer are a failing hard drive, Bad RAM modules, Viruses, Or the hardware is just plain worn out.

Ram is sold in differnet sizes which is the most realized factor of ram. but Ram is also sold at different speeds.

If you have 4gb of ram at 800mhz each then 2gb of ram at 1333mhz would still outperform the slower 4 gb. Make sure this is not the problem (would only be if you changed the ram and encountered problems)

Run a memory testing program, there are thousands of free ram test programs for free.

Try different ram sticks.

Backup important files and reinstall windows (this will fix 90% of slow computers)

Try a different hard drive: you will need to install fresh or take an image of drive and put it on new drive. (if you image your drive make a partition on the new drive that is as close to the same size as you can to avoid problems.

Outside factors that affect connection speeds Unfortunately, there are events and conditions that are outside your control. Even with a fast connection, external factors, such as busy websites or spreading computer viruses, can slow the entire web. Popular websites can become overwhelmed with users. For example, when a television commercial mentions a website, many people might try to visit the site at the same time. If the website isn't prepared to handle the traffic, you might encounter delays. During times of heavy computer virus outbreaks, the Internet can slow down. Many viruses spread by causing computers to send out hundreds or thousands of copies of the virus. This can slow the Internet by sheer volume. You can see what major outbreaks are currently happening by visiting your antivirus vendor's website, or the Security at Home website. Local Internet congestion can also result in slower-than-normal connection speeds. These slowdowns occur when many people try to connect to the Internet at the same time, and they occur most often at peak activity times, such as after school hours when students get home and connect to the web. If you're on a corporate network, general network and proxy server use can affect your Internet performance. Most network administrators monitor Internet use, and will try to keep people from doing things like downloading large files during peak hours. If you find that your Internet access is slow at times, you might discuss it with your network administrator.

my gx270 PC runs very slow after installing anti virus. what might be the problem?hat might be the reason?


Some anti virus software can use up a lot of system resources and noticeably slow down a computer. The newer and faster computers don't suffer from this problem as much, but on an older computer like your's it can be a problem. I've used Avira (free) on older computers without a problem:
http://www.avira.com/en/support-download-free-antivirus

I don't usually recommend Microsoft products, but Microsoft Security Essentials is not only a very good product and free, but it runs well on older, slower computers:
http://www.microsoft.com/security_essentials/?WT.srch=1

AVG is a good free anti virus also, but it sometimes can slow down a computer a bit. I'm running it on some Netbooks with an Atom 1.6GHz. processor and it does OK. Only way to find out is to try it:
http://free.avg.com/us-en/homepage

Remember that you should only run _one_ anti virus software at a time, so don't forget to un-install the existing anti virus first.

If you purchased an anti virus product and you're stuck with it, this tip may help you speed up your computer:

Also, your may be able to increase your performance with a memory upgrade. If your not sure how much or what kind of memory that you have, download and run this:

Scroll down to the SIW Without Installer (English-Only) version. After it's running click on "memory" in the left margin.

computer gets very slow by downloading anti virus....plz help me


The anti virus is needed for computer to protect from the viruses .
The anti virus consumes certain amount of cpu and memory usage.There are anti viruses that consume large amount of memory and CPU .
If your system have higher memory and CPU performance you can use any anti virus so that the performance is not downgraded to very much.

If you not having more memory and higher CPU in that case you can use anti virus that can consume less memory and also you can stop services in antivirals which are not necessary
