I think my computer has been infected with a virus through a pen drive. When I open task manager, it opens up for a second and then disappears. My VLC media player also stopped working and the computer's been running really slow lately. What do I do?

SO run an Anti-virus scan. Or have you already? If so what did you use? I recommend MALWAREBYTES...

Always use licensed version anti virus,
quick heel is best anti virus now first scan your computer with quick heel after that restart it.

All sorts of free & sharware software can be found at filehippo. If you don't have a decent antivirus program, I recommend either AVG Free or Avast!. Both Norton & McAfee are over-bloated resource hogs & should be avoided.

You should also install a cleaner such as CCleaner-Slim & run it regularly. Get the last one on this list:

And use MSCONFIG to disable useless programs from loading at startup:

Thanks to all you guys, specially ace_omega. I ran malwarebytes and the task manager problem has been resolved. It found 14 infected objects. Although my system is still slow, the speed has significantly increased.

You suggested ccleaner; do you think I should mess with the registry?

And which antivirus to go for; one of you recommended AVG and the other quick heel? I've also heard about Kaspersky.

jojee, a 'maybe'. A common ailment is a file called 'index.dat'. It gets read every time and can take quite a while if it’s too bloated. It's like a log file and keeps a record of every site you visit on the web. Empty, it's 32K, but it can grow HUGE. It's a protected file and can't be deleted by normal methods. CCleaner can get rid of it when it’s ticked (not to worry, it gets rebuilt EMPTY on the next boot.). May not be your deal at all, but won’t cause any harm to try. I run it often (daily as I mess with LOTS of DLs). Since you already have CCleaner, seems to me you just need to configure it.

re' which virus util?

I favour avast.... ( free for home use. avg is also popular but I have had some issues with in the past with '9x/ME and one XP installation...; none to date with avast.

Any virus scan is best done in safe-mode; and also with system restore disabled. Once a given system is clean... reboot and then re-enable system restore; but before rebooting... delete "anything" that is quarantined, and then empty the recycle-bin; "then" reboot etc.

Disabling system restore prevents that item re-installing/restoring the (now missing...) pests that will also have been be "registered/recorded" etc. in the registry and elsewhere...

Before you run any "cleaner" - especially registry cleaners... FIRST back up the registry; and be sure you know to restore that back up if needs-be - following the mess some clean-up utils can leave behind...

I have had not at all happy experiences with ccleaner; and have read of others similar too. And likewise with other similar "cleaners". (Had to rebiils an XP-Pro system after the predations of ccleaner and also one '98SE...) But in fairness many have found ccleaner OK... But again back up the registry first...

IE has the option to dump all cookies, temp internet files etc... and also to clear out the history... And you can manually run disk-cleaner (part of XP) to clear out junk files...

Also defrag the drive...; and if using the XP defrag util... run it a couple of times; as one pass often doesn't do all it might..
