Hi, just continuing the previous posting, how to make everything run faster?. Here is another tip for you. Read it. Hope ths can help.
Scan for malware with online tools
The best way to keep your PC free from viruses and spyware is to run a good antivirus application and keep it updated. But if you've been bad and left your computer exposed to the depredations of the malevolent, you can quickly find and eliminate skulking intruders either by running a portable security program -- one that doesn't have to be installed onto your system -- or by using a Web-based scanner.
Conveniently, Ewido Networks (now part of Grisoft, which produces the AVG antivirus utility) provides excellent tools in each category -- and both of them are free. Try the online Ewido scanner (which works only with Internet Explorer) or the free stand-alone program, which is available for downloading. Both versions update their definitions when you use them. Other good options are ClamWin Portable and Kaspersky Lab's Web scanner.
