Virus Tutorial: Detecting viruses through Windows Task Manager (Part II)

2010-03-14T23:32:00.000-07:00

Once, my computer became slow after I plugged a flash disk without scanning it first. I assumed it was usual if a computer became slow, but I finally detect that there was something wrong. Finally, I searched the information and found out that it was because local viruses. They duplicated folders so the harddisk became full.

I tried checking through Windows Task Manager by pushing Ctrl+Alt+Del in one time. There I found applications with weird names running by consuming huge memory. Sometimes the processes can not be deleted (End Process), but don’t panic. There are several ways to stop those unwanted processes.

1. Try to show Windows Task Manager, if it is disabled by the viruses try to use softwares there are in internet. Googling with the keyword “cprocess, Autoruns, iKnowProcess and ProcessExplorerNt.

2. If it doesn’t work, try safemode. Generally, most viruses aren’t active in safe mode. We can enter into safe mode by pushing F8 botton when Windows restart after bios screen showes up dan before the sign on Windows appears.

If it still doesn’t work, there are several ways such as using MSconfig. We’ll talk about it in some other time…

May this writing is useful for you…

Virus Tutorial: General Guidline to Eliminate Virus (Part I)

2010-03-14T23:12:00.001-07:00

Recently, viruses have rised in a lot numbers of variant. Appearing in a new form and ability, however a virus is still a virus. It leaves the identity as a virus. For Windows 98/2000/XP we can recognize the existence of the viruses at several places. Those places are:

Windows Task Manager. This could be an early detection of the viruses. Pushing the Ctrl+Alt+Del we are having Windows Task Manager >> Processes. And then, find files with akward name (you surely have to be familiar with general aplication that exist in Windows to avoid mis-clicking). When the viruses have been found, right-click on the mouse and End Processes. There are several cases when the aplications cannot be executed. But we can handle it through the save mode using little free software from our uncle google.com.

Msconfig. Some viruses using this area to load themselves when windows restart. Therefore, when we have terminated those viruses (uncompletely), it won’t delete the tick mark of startup items in Msconfig>>startup. So, those viruses will create the missing parts when restart. We can delete the tick mark of startup items in Msconfig>>startup with typing Regedit at START>>RUN.

Regedit. The place where viruses put the identity in. By typing Regedit in START>>RUN then click Edit>>Find, type the keyword or the virus name. When we have found one/s, we can directly delete it/them.

Goodluck………
