Hi everyone...i have this problem and i hope you can help me out.
The size of the files stored on my hard drive spreads and occupies about dbl its original size....
for example...a folder size is 464 Mb...occupies 929 Mb????
i hope you can help me with this...and thanks in advance...

Sounds normal to me. Are the files Blue in color, as in compressed?

From a Purdue University newsletter on viruses:

"There are several warning signs associated with the downloading and execution of viruses. Files increasing in size randomly, the appearance of unknown files, losing files, the inability to save files, corrupted files, sudden lack of hard drive space, the inability to access programs, your system not starting or closing correctly, or strange messages appearing on your screen are all telltale signs that you might have a virus on a disk or on your hard drive."

If you're not sure about your anti-virus program, or don't have one, it may be worth giving the free scan listed above under Virus Info a run.
