Thread: suspicious folder that has appeared by itself

I noticed a folder called Main_files in D: drive(dated july 18,2010),which I have not created.Could my system be under virus or hacking attack?
Please reply soon.

More details needed.
Virus may not create a folder in C: or D:
Check Properties of the folder. Total size?
Number of files and extensions: exe files etc.
if you run VIRUS/ anti spyware applications
this folder will be listed if infected
Presume your OS and Program files are in C:/.
May be an automatic back up of files in C:? ?

Well for me i have two suspicious folders with the name of katrina kaif. Help pls.

I deleted the folder so dont know about the size.
Now,I have changed the settings to show hidden files also.And in almost every folder containing pictures there`s a DAT file called zb4.INFO or with similar names..each with different sizes.What could they be?

Which antivirus do you use ? Run a full system scan or scan those folders individually. Report the result here.

I use Kaspersky Internet Security 9.0.0.736

Here are the full system scan results:

Please reply soon.

No, that's not a virus. It might be just a system file or a temp file created by a program. Use a good AV and do a full scan. by a good AV, I mean Norton Internet Security, kaspersky Internet Security, or Eset Nod32.

All of these have a fully functional 30 day free trial. Download any one and do a full scan. And, NEVER use 2 AV's together. Hope that helps. Tc.
