I'm not exactly sure all the information I should include but... I have a Toshiba Satellite T115-S1100 running Windows 7 Home Premium 32-bit. Installed on laptop are AVG Anti-Virus Free Edition 2012, avast! Free Antivirus, and Symantec Endpoint Protection Small Business Edition. Initially, I did not know the potentially harmful effects of having all of these at once. I know now that I should only have one of these, after attempting to search for solutions to my problem. After much searching, I realized that many of the possible solutions did not match my exact situation. There were a few valuable pieces of advice that were bought to my attention. I knew that I should not delete any programs, and that the posted solutions were often meant for only the posters. Both AVG and Symantec had been on my laptop for quite a while now, at least for one year. On July 22, 2012, I installed avast! onto my computer. For almost a week, there had been no problems brought to my attention. But Friday, July 27, 2012 was when the problems began, and continue today. I do not know what I did to cause these problems on my laptop, but they are here now. As a brief side note, AVG did not have similar notifications, or any for that matter. Every time I start up my laptop, a window labeled "Symantec AntiVirus Detection Results" pops up, listing numerous risks that it has found. There are hundreds and possibly thousands of these risks listed. Each entry is nearly the same except for the file name and the date and time they were quarantined. The file names are trz****.tmp, where **** represents a combination of letters and numbers. It tells me that the risk is "Trojan.Gen", that each one is "quarantined" or "pending analysis" (although the vast majority are pending analysis), and that the risk type is "file", that the original location is C:\ProgramData\SYMANTEC\SRTSP\Quarantine\, along with several other pieces of information (computer, user, status, primary and secondary actions, and what it was logged by). In addition to the window from Symantec, I get notifications from avast! telling me every few seconds that a dropper has been blocked. These notifications say that avast! File System Shield has blocked a threat and that no further action is required. The object is C:\PROGRA~2\SYMANTEC\SRTSP\Quarantine\APQ****.tmp, where **** represents a combination of numbers and letters. The infection is MSIL: Dropper-RS [Drp]. The action is not specified, and the process is C:\Program Files\Symantec\Symantec Endpoint Protection\Rtvscan.exe. I have scanned my laptop a couple times from the time I first received the notifications with Malwarebytes Anti-Malware and avast!. Both were updated, and both found risks, but not even close to the number of risks that had been detected. Ever since I began to receive these notifications, my laptop has slowed drastically. Documents, files, etc. take much longer to open than they normally would. Internet connection, too, has been spotty and slow, with some pages, including YouTube videos, unable to be displayed. The CPU runs at 100% constantly. Full systems scans that would usually take around two hours now take over eight hours. I apologize for the length of this initial post, but I wanted to be sure that I included as much information as I could. I will appreciate all help that I receive.
