I am currectly trying it remove tons of viruses from a friends laptop. This thing had some of the most crap I have ever seen. This laptop was given to him friend a family member. I have used Corperate addition of Symantec,Trend Micro's House Call and SDFix. Can no longer use Symantec due to system ram. It just takes up to much. Weighs computer down. I have tried some other malware programs. Used SpyDoctor and that helped a little bit but later uninstalled it as it was no longer any use. The computer had a program called Anti MalGuard. Not sure what that was as I simply deleted it. It would not work anyways due to that fact the internet was not working but I got that fixed. I found which virus was causing the net problem and got rid of it, though it did take awhile. I also tried to use Malwarebytes but for some reason that program just hangs on dll files. Tried it like 3 or 4 times and it would start than scan for roughly 10 seconds then just hang on a dll file. I did let it sit there on the dll for like 20 minutes but I figured something was wrong and tried to abort but that would not work. I had to use task manager to close the program. Not sure if it's the viruses causing a problem or the low system ram. The computer does hang from time to time but what is exactly causing it is unknown for now. I would assume the viruses. All of the above have worked and failed. They worked and got rid of most virus/malware and some they did not get rid of. My friends computer only has a 9 gb hard drive and only has 190 mb ram so installing things can be tricky with not alot of space and very low ram. 3 malware/spyware are still left on the computer according to Trend Micro's House Call that I have tried but failed to get rid of. House Call cannot get rid of them nor has any info on them. All I got was mainly to contact their support. These are the 3: Malware: TROJ_DLOADER.HAB TROJ_SCAPUR.C Spyware: ADW_PURITYSCA.ED If anyone knows how to get rid of these 3, I would appreciate it. Been trying for a couple days but so far no luck with these 3.
