Windows 7: What is the pdf.exploit that my scanner keeps talking about

Whatever it is i have been cleaning it of my machine every time i scan my machine.

I did get i virus a month or so ago but i got it of relatively quick.

Should i be concerned about these?

Also according to avg it found it while it was trying to turn on or something.

Is it like tracking cookies always there being a pest but never doing real damage or is it something bad

Thanks for replies also here is a pic

P.s also what are those java things

Hi computergeekguy.

Firstly I would remove AVG and replace it with Microsoft Security Essentials & Malwarebytes. Why? Because Microsoft Security Essentials has better detection, is lighter and doesn't cause BSOD's.

I would then run a Scan using Microsoft Security Essentials and Malwarebytes to see if it can detect and remove it.

Next if none of this helps, I would either Disable or Update Java on every Browser or uninstall it completely until the infection is gone.

If Malwarebytes or MSE finds and removes the infection, run an SFC Scan to repair any files the virus could have corrupted.

PDF exploit is Adobe ... it's in a temporary file location

TFC (Temp File Cleaner) will clear out all temp folders for all user accounts (temp, IE temp, java, FF, Opera, Chrome, Safari), including Administrator, All Users, LocalService, NetworkService, and any other accounts in the user folder. It also cleans out the %systemroot%\temp folder and checks for .tmp files in the %systemdrive% root folder, %systemroot%, and the system32 folder (both 32bit and 64bit on 64bit OSs). It shows the amount removed for each location found (in bytes) and the total removed (in MB). Before running, it will stop Explorer and all other running apps. When finished, if a reboot is required the user must reboot to finish clearing any in-use temp files.
