Either or both or neither may have a virus. Sometimes it's a friend's computer or a web server that has been hacked and the contact list stolen and used to send out spam.
Eset's free online scan is a good thing to do. Can take several hours but it's very thorough.
Use IE and go to http://eset.com/onlinescan
and click on ESET online Scanner. Accept the terms then press Start (If you get a warning from your browser tell it you want to run it).
# Check Scan Archives
# Push the Start button.
# ESET will then download updates for itself, install itself, and begin scanning your computer. Please be patient as this can take some time.
# When the scan completes, push LIST OF THREATS FOUND
# Push EXPORT TO TEXT FILE , and save the file to your desktop using a unique name, such as ESETScan. Include the contents of this report in your next reply.
# Push the BACK button.
# Push Finish
# Once the scan is completed, you may close the window.
# Use Notepad to open the logfile located at C:\Program Files\EsetOnlineScanner\log.txt
# Copy and paste that log as a reply.
MBAR is another good scan:
Or you can do a frst scan and let us look at your PC to rule out a virus.
Get FRST from http://www.bleepingc...very-scan-tool/You need to download the appropriate tool for your PC. If you don't know if you have a 32 or 64 bit system get them both. Only one will work and that's the right one.
Right click to run as administrator (XP users click run after receipt of Windows Security Warning - Open File). When the tool opens click Yes to disclaimer.
Check the Addition.txt box
Press Scan button.
It will produce a log called FRST.txt in the same directory the tool is run from.
Please copy and paste log back here.
It will generate another log (Addition.txt - also located in the same directory as FRST.exe/FRST64.exe). Please also paste that along with the FRST.txt into your reply.
