I know that you have Panda AV, but it may pay to try one of these. Theory is that it is possible that your resident AV could be affected by any malware, whereas an online scan will not be. First clean:
==Download this temp file cleaner from
http://www.atribune.org/ccount/click.php?id=1 --click in the download window to run it, and when ATF Cleaner opens go Select all, and then Empty Selected.
Next click Firefox [if you have that browser..] at the top, Select All again, and Empty Selected again. Follow that procedure also if you have Opera.
Close ATF.
Just in case:
==AVG AntiRootkit from
http://free.grisoft.com/doc/5390/lng/us/tpl/v5
One of these two:
==Pandasoftware ActiveScan using IE only from
http://www.pandasoftware.com/products/activescan? - just follow through the pages, supply a "valid" email address... To reduce the number of detections run either CCleaner or ATF cleaner first [to remove cookies].
==Kaspersky Online Scan, from
http://www.kaspersky.com/virusscanner -press the Kaspersky Online Scanner button, follow through....
Sorry I cannot help further.
