OK, sounds like someone has done some tinkering...we'll troubleshoot the "Office" issue later, let's search for malicious code...
Please temporarily disable your on board protective programs as detailed
Here. Carefully read through that entire thread to make certain any and all programs YOU have on board are disabled.
Next:
It is extremely important that you DO NOT close this program until or unless you are directed to do so. Once the program is closed, it will automatically uninstall itself taking with it anything that was removed and the related report.Please read through this instruction thoroughly before you begin. Save these instructions in a notepad file, or print them out if necessary so you can refer to them should something go wrong for you during your attempt to carry out these steps. If you have any questions, please ask first before you attempt anything at all.
Please download the
AVP removal tool to the desktop and double-click the executable to install it. Select your language preference, accept the agreement and click the
Start button. You should see something like this:

...click the settings button...it's the small "Gear" icon just to the right of the large yellow button. Make sure the following boxes are checked:
System memory
Hidden startup objects
Disk boot sectors
Computer...Next, click the
Actions link and click the bullet item labeled "Select action".
Disinfect and
Delete if disinfection fails should already be checked by default...then return to the
Automatic Scan tab and click the
Start scanning button.
If you happen to receive a pop up during the scan which reads "File C:\whatever...is password protected, you can safely ignore them. The program will find it's own password protected files and report these during the scan. If there is a genuine malicious file that is password protected, we will deal with it manually later.The scan will begin and you will see a progress bar and scanned objects counter. When the scan completes, the progress bar will disappear. Click the "Reports" tab icon to the far right, just under the large yellow button. Click on the "Automatic scan report" link, then click the save button. Save the report to your desktop as
Scan 1. The report will be saved as a text file.
That file is going to be very large...too large to post the entire thing. What I need you to do at this point, is to open that log in "Notepad", then click
Edit from the menu at the top and select "Find". Using that
Find search function, use these as search terms:
Disinfected
Cleared of viruses
DetectedNow...you'll need to search for those terms in that log, one at a time. Having selected the "Edit-->Find" function in Notepad, in the
Find what search box, type in the word
Disinfected then click the
Find Next button. The search function will find anything in the text file having the name "Disinfected". Once it presents the findings, copy that individual line item and paste it into another blank notepad, then continue searching by clicking the
Find Next button. Do this in like manner, for each of the search terms identified above. Once you complete the search and copied everything you found into the other blank notepad, save it to your desktop as
Edited_AVP_Log.txt.
Next, please return to the AVP scanning utility and click the
Manual Disinfection tab. Please click the
Start gathering system information button. You'll again see a progress bar while the utility collects the necessary information. When it completes, the progress bar will disappear. Click the "Report sending" tab, then click on the link
avptool sysinfo.zip (open the file manager). Attach that zip file here on your next reply along with the contents of the "notepad" file that you saved from the above "First scan" instruction. Thanks!
