Good day, I have received a Resident Shield Alert on the following:
File Name: c:\\windows\system32\drivers\ulmxcpqi.sys
Virus identified: win32/patched.ev
I have scanned my laptop and AVG placed the file in my virus vault. I have tried to search for a removal tool for this virus, but cannot find one. Can you please provide me with information how to remove this virus. My computer is also very slow, I am using Windows XP.

Thank you

When an anti-virus or security program quarantines a file and moves it into a virus vault (chest) or a dedicated quarantine folder, that file is essentially disabled and prevented from causing any harm to your system. The quarantined file is usually renamed before moving, safely held there and no longer a threat until you take action to delete it. One reason for doing this is to prevent deletion of a crucial file that may have been flagged as a "false positive" especially if the scanner uses heuristic analysis technology. Heuristics is the ability of a scanning program to detect possible new variants of malware before the vendor can get samples and update the program's definitions for detection. Heuristics uses non-specific detection methods to find new or unknown malware which allows the anti-virus to detect and stop if before doing any harm to your system. The disadvantage to using heuristics is that it is not as reliable as signature-based detection (blacklisting) and can potentially increase the chances that a non-malicious program is flagged as suspicious or infected. If that is the case, then you can restore the file and add it to the exclusion or ignore list. Doing this also allows you to view and investigate the files while keeping them from harming your computer. Quarantine is just an added safety measure. When the quarantined file is known to be malicious, you can delete it at any time by launching the program which removed it, going to the Quarantine tab, and choosing the option to delete.

Important Note: In some cases a Win32.Patched threat detection can be indicative of a dangerous polymorphic file infector such as Virut which typically infects .exe files. I recommend you get another opinion by trying an Online Virus Scan to see what they are detecting.-- Kaspersky and F-Secure requires free Java Runtime Environment (JRE) to be installed before scanning for malware.
-- If malware is detected and you are given a choice, select "Quarantine" instead of Delete.
-- Some online scanners will detect existing anti-virus software and will not work properly. You may have to disable the real-time protection components of your anti-virus in order to complete a scan. If that's the case, please refer to How To Temporarily Disable Your Anti-virus. If you do this, remember to turn it back on after you are finished.
