Since the virus is stored at the hard disk when placed,yes
examples are:
-It deletes files needed to run a system
-Tracks down your activity and private information
-It also slows down pcs
and many more......

Did she download any AntiVirus program?
several of these at the same time may be the cause of the sluggishness
especially when they are scanning at the same time

Also,did she got recently infected with a particular virus?
After reformatt of her PC?

that PC had never been infected before.It has now anti virus.
Is it possible that the virus will get stuck in the hard disk even after reformatting?I thought it is the best option to resort to when pc is severely infected?

1, If your hard disk was reformatted after the virus attach, the disk would have been wiped clean and the operating system would have been re-installed. Now if this was the case, the virus would no longer be on the hard drive.
2. The only reason for replacing a hard drive would be the discovery of "bad" sectors that could not be read or written to. You can run Windows Check Disk and configure it to check the physical disk for bad sectors; be advised this will take some time.
3. There can be many causes for sluggishness. I would suggest to follow the checklist below:

Let us know what happens.

Not quite sure but a theory of mine passed on to my mind
Only one thing on my mind struck me the most
Its a bogus AntiVirus (AV) called "SpyFalcon"
It is said it can withstand uninstallation attempts
But im not really sure if it can withstand reformatt attempts
Why not check her PC for malware by using HJT log and post it at the HJT forums?
Just to make sure that malware may not be the cause

Also can you tell us the name of the Anti-Virus program she has?
Because some of these products like Norton which is known as a memory hog
slows down most PCs

If after running windows check disk and viewing the application log at the event viewer and the hd has not been found with any bad sector or no problem at all.Can we bank on that?That the hd does not need to be replaced.Does check disk sometimes fail?I still could not find the name of the antivirus she has.I havent got any answer as yet.Tnx.

Although rare these days (I haven't seen one in a while), a boot sector virus will remain even after a normal format. The "fix" is to use a low-level formatting utility (usually available for free from the manufacturer of the hard drive) and then proceed with the partitioning and formatting of the drive.

LLF will be done from a boot floppy or CD. It needs sole access to your hard drive (so you can't do it from Windows).

You can do a low level format using the HDD Low Level Format Tool from this page.
