To prevent computer attacks, you should have a good virus protection service. Second, you should never open emails from a person you don't know. There can be loads of viruses in there. Third, make sure nobody knows your IP address. If someone has access to your computer, that's dangerous. And finally, you should have your computer set to the mode that warns you that a website is dangerous. If the website that you're on says secure browsing/server is on, then you're good and you don't have to worry about computer attacks from there.

If your computer is infected by a Virus?
If your computer is still working and you have Anti-Virus software installed - update and run the software. If you do not have anti-virus software you should download a free antivirus program (AVG, Avast, and Avira are good choices). If your computer is compromised and you cannot download/install this software - you may need to download/install the software onto a flash drive on a different computer and then put the flash drive in your computer to scan.
If this does not fix the problem you may actually have Malware or Spyware. You will need run or install software to scan your computer - there are many free options and you should try several (Malwarebytes Aniti-malware, Spybot - Search and Destroy, and SuperAntiSpyware are good options). After installing/running these you should take care of almost anything.
If your web browser is redirecting and you cannot search for software - you may need to use another computer to find the software - or use a less common search engine to find them. There are links below as well that you can use to download them.
If after running the anti-virus and anti-malware/spyware programs your computer is still not working properly you may need to have it looked at by a professional computer repair technician.
What are the most common routes a computer system can get infected with malware?

Can a computer become infected via email?
Not normally through a simple text email. However, a virus can enter a pc through a link to an infected site or a malicious attachment. ... Yes an email can have a virus in it, but usually you have to click on a link. The basic rule is if you have been sent an email by someone you do not know, have not asked for that email then treat it with caution. Never respond to an email from someone you don't know and have a process whereby any attachment sent to you by people you know or have asked to send you something is scanned by an updated antivirus software before opening
Databases tend to get split up into a variety of diffrent catagoies based on their application and requirements. All of these diffrent catagories naturally get nifty buzz words to help classify them and make distinctions in features more apparent. The most popular buzz work (well, acronymn anyway) is OLTP or Online Transaction Proccessing. Other classifications include Descision Support Systems (DSS), Data Warehouses, Data Marts, etc.
OLTP databases, as the name implies, handle real time transactions which inherently have some special requirements. If your running a store, for instance, you need to ensure that as people order products they are properly and effiently updating the inventory tables while they are updating the purchases tables, while their updating the customer tables, so on and so forth. OLTP databases must be atomic in nature (an entire transaction either succeeds or fails, there is no middle ground), be consistant (each transaction leaves the affected data in a consistant and correct state), be isolated (no transaction affects the states of other transactions), and be durable (changes resulting from commited transactions are persistant). All of this can be a fairly tall order but is essential to running a successful OLTP database.
Because OLTP databases tend to be the real front line warriors, as far as databases go, they need to be extremely robust and scalable to meet needs as they grow. Whereas an undersized DSS database might force you to go to lunch early an undersized OLTP database will cost you customers. No body is going to order books from an online book store if the OLTP database can't update their shopping cart in less than 15 seconds.
The OLTP feature you tend to hear most often is "row level locking", in which a given record in a table can be locked from updates by any other proccess until the transaction on that record is complete. This is akin to mutex locks in POSIX threading. In fact OLTP shares a number of the same problems programmers do in concurrent programming. Just as you'll find anywhere, when you've got a bunch of diffrent persons or proccesses all grabbing for the same thing at the same time (or at least the potential for that to occur) your going to run into problems and raw performance (getting your hands in and out as quick as possible) is generally one of the solutions.
Several other factors come into place with OLTP databases, and the Oracle10g documentation library even has a whole section dedicated just to OLTP. Find more information in the Oracle10g docs:

The above was probably written by someone from Webfetti. (They always deny any malware) It looks cool but the price is Too high. Avoid it!

What can you do if your computer is running slow?
Are you using xp?
Xp has very cool features, however it demands lot of memory from your PC...try disabling some features to use less memory...like using the classic desktop instead of the colorful one...you can do that on PC settings and task bar menu...
Also go to the settings and hit on System...there go to the advance tab and click on performance settings, there uncheck all option you think won't affect your computer and that will help faster up a little...

To speed up your computer and free up space and memory for free:
Go to the Start Menu> Run
Type in "appwiz.cpl"
Uninstall whatever you don't need.
Next, go to Start> Run and type in "msconfig".
Go to the Startup Tab and uncheck everything you don't want to startup. If you want, you can uncheck everything, and your anti-virus will still restart itself when you log on.
Now go to My Computer> Hard Drive> Documents and Settings> [USER NAME]> Local Settings> and delete everything inside the Temp Folder. (This is a hidden folder so you will need to have "show hidden files and folders" checked in Folder Options) All the files in this folder are just temporary files that your Internet stored that for certain websites.
Then go to My Computer> Hard Drive> Windows> Prefetch and delete everything inside it. This folder is like an cache for programs and should be emptied about once a month.
Next, you should install CCleaner, it will get rid of a lot of temporary files on your computer. It also has a registry repair system, which is easily the best free one available on the Internet:

Another option is to try defragmenting your computer.
Go to the Start Menu and go to All Programs
Go to Accessories and System Tools.
Choose Disk Defragmenter and when it loads click defragment.
Next, go to Device Manger (Start> Right Click My Computer> Properties> Hardware Tab> Device Manager) and update all drivers.
Another thing I would say is to compress your files if you already haven't.
Open My Computer and right click on your hard drive
Check the Compress Drive button and let it do its thing.
Finally, make sure your Hard Drive doesn't have any bad sectors. Go to My Computer> Right Click Hard Drive> Properties> Tools Tab> Check Now> Check both boxes and Start. It will ask you to reboot, so reboot. This will clear out any bad sectors on your Hard Drive.
These are short-term solutions however. The easiest way is to just upgrade the RAM on your system, but at least the ways above are free.
