There are many websites that help you test your computer, evaluate its performance and diagnose any potential problems. Some of these websites are really treasures as they will improve the performance and security of your computer, while the rest are just a little bit of a marketing tool.

http://www.trojanscan.com
Trojans are programs that are installed on your computer behind a useful or entertaining application. Once you have resided on your computer, a Trojan can destroy data or help attackers to easily penetrate your computer. In this respect, it is similar to the legendary Trojan horse. Some antivirus programs can detect trojans, while many other programs can not. For your safety, you really need to be very careful when installing new downloadable programs, by checking their backgrounds carefully and by installing a dedicated Trojan scanner.
Trojan Scan does the same job as an online virus scanner, but it only focuses on trojans. When you download the Trojan scanner, you can check which drive you want to scan the Trojan. This may take some time, so if you perform a Trojan scan at a time when you are not using the computer, it is best to do so.

As an online virus scanner, Trojan Scan can not scan for trojans in newly downloaded files, so you can not get protection on a continuous basis. However, many of today's leading commercial antivirus programs also include Trojan scanning. You should consider using one of these programs for continuous protection. This is an updated scanner to kill all Trojan horses in the Trojan Scan database. The scan is relatively slow. The exact time will depend on the size and contents of the hard drive. If you use a dial-up connection with a timed access time, this process will be very expensive.

http://housecall.trendmicro.com/
This site is a product of PC-cillin and is one of the few websites that offer free virus scanning on the Internet. All of these websites will scan your computer for viruses and display the results for you to see and then invite you to purchase their anti-virus program.
While you should not go to the Internet without an anti-virus program running on your computer, HouseCall and similar sites may provide a solution to block the vulnerabilities, if the license is used. Your antivirus software has just expired or if you want a virus scanner to be sure. There will be no conflict if you scan the virus online while you have a virus scanner installed, but you will need to turn off the ongoing protection feature of this existing program.

You have a virus scanner online and you can play a word game while scanning. However, the sales promotion nature of the charade game and the scanning process may make you think it is not a totally free service. Their goal is to make you buy PC-cillin, but the assertion that you can not rely solely on online virus scanning sites like this is absolutely correct. It's very good, but not a replacement for an anti-virus program installed on the machine.

However, it focuses on the performance of hardware and software, provides hints that emphasize the importance of fragmenting your drives and installing enough RAM. The test is pretty thorough but it takes a bit of skepticism to see the results.

Most other antivirus software companies offer a similar online service, for the same reasons. TrojanScan is another variation in this area, although marketing is less obvious.
